Life as it is...

Right... haven't updated anything on the blog so far, but we've been having a flurry of activities...

First... Keisuke caught on the act of eating too much!!!!
Keisuke caught on the act
(OIII Youre going to get fat real soon if you keep that appetite up!!! xD)

Sadly since my dad took our camera for his business use :( so most of our activities were not captured on film :P

So we have been to 2 trips to Jln Sg Tekali Touge, wicked place for our noob level of skills :P

Sg Tekali Touge
(Hmmm... not sure if you can see it >.< ) Our first trip was merely just scouting the touge, we had passed through the touge once before with our normal daily cars so we just wondered how it will feel like if we were to go with the FC on that slice of road^^ Not to mention just because I just did an alignment check on the FC that day, just wish to feel how it feels on the touge^^ Alignment setting
(This is the previous messed up setting of the FC, obviously the FC has been seeing too many action without us taking a look at what those abuse has done to the alignment setting... :(
Just to share what the monitor shows:
Left front toe : -5.7
Front total toe : -12.8
Right front toe : -7.0

Left front camber : -2.46
Front Cross Camber : 1.27
Right front camber : -4.13

Left wheel caster : 3.03
Cross Caster : -0.12
Right wheel caster : 3.15

Yeah I know the setting is all screwed up :( thats why the FC felt soooooooooo nice after the service xD )


So our first night there was only the 3 of us... me, Keisuke and Cloud. And only with the FC, we went there almost close to midnight... and the touge were far more challenging than we thought.

The Sg. Tekali Touge were higher in altitude compared to most of our usual touge places, and the elevation was rather steep as well... so obviously being thrown left and right at high altitude need some getting use to :P

So the first night ended with all 3 of us getting our share of car sickness xD with Cloud almost to breaking point >.< Our next trip was with Keisuke's buddy, Azhan... he have a beautiful 1.3 M/T Satria, and when we were just about to have fun we found a problem with the FC turbo unit... a leak turbo gasket!!!! :( AWWW dang, there goes the FC into the workshop again :P Anyway, just as of today (28th dec) I went to Shah Alam to help my cousin register into UiTM... and just my lucky day, there is an AutoCross Championship being held at the Shah Alam Stadium!!! :D So here are some pics and vids of the day^^ enjoy!!! (Sorry for the bad quality pics and vids because we had to use our handphone camera :( ) Wicked MR2
(Nice and Wicked MR2 making its run^^)

A minute after midnight....

Gimme a minute after midnight...
(Classic ABBA song^^)

That what was our plan last night.... we had to pick up our mom at midnight, but we were too busy playing with the FC that only half past midnight did we remembered to pick her up!!! :-O

OMG!!!!

Anyway, last night started pretty slow... we just wanted to chill with the FC, not some full blown touge run, so we headed to our normal training ground... the cleared Pasar Malam area....

But when we arrived there, there was a cop waiting silently there... since we don't want any entanglement with the gangsters in white uniform... we decided to head to Putrajaya to 'lepak' at our normal bridge :-P

But that night it seems our 'normal' bridge is quite pretty occupied, with a lot of people passing by making us uncomfortable... so we headed to the PICC brige with is a lot bigger^^

Photobucket
(Keisuke and Zid driving around PutraJaya)

So we stayed there until close to midnight and off to the pasar malam lot again, and now its empty!!! :-D

hehehhe.... so we had a couple of empty water bottles to act as cones and we made a couple of drift attempt...


(Here's a vid of Keisuke trying to drift 90 degress through the cones^^)

Tried to do the big donut but never happened... and as I said before... it was past midnight, and we forgot our mom!!!! :-o

So we sent Zid back home and off we went to pick our mom with the trusty Howling Banshee :p

She was quite disappointed with us but what can we do =.=

The next night, the drift frenzy is still not over... we headed to the pasar malam lot quite early and bought a couple of mineral water as our cones again.... (got to buy a real one =.=)

This time around we were getting better... then a fellow drifter comes by and makes a donut... he was damn cool in his A31 Cefiro.... we chatted for a while then we continued with our tyres burning^^

But suddenly Izam (The Cefiro drifter^^) scoots off, Keisuke and I was wondering why when we noticed a parked cop in the dark alley.... SH**T!!!! We made a run for it (rather coolly actually :P) and went to buy us some drinks first with an old friend^^

Then when we had our fill, we went to the Pasar Malam area again and the Cops were gone... hehee, another round of drifting while the road is still wet^^

So there we go again, and Izam also came back... we were just having a blast of time and then a truck driver came, it turns out he is a drifter too!!! :-o

Goes by the nick name of Pok Nik, he drives an old Datsun as his drift car... he tested the FC to do some donuts and figures of 8 and it was FUN when he's behind the steering wheel!!! :D

Izam had to go back early since him and his friends had to work the next day, so Pok Nik tried the FC a couple of rounds and heads back looking for his container :P

He gave us a few tips to make the FC a better drift car (Thx Pok Nik ;) and off we went our separate ways....

That night was awesome, we went back home at 1 am, dead tired but exhilarated^^

hehehe... it seems I have to quickly acquire those new tire sets for these kind of things^^

Drift and Touge... what a life^^

The Night the earth stood still....

The night was still and the road was clear... the plants was dancing with the breeze and the animals were well asleep... until the tremors of the earth shook everything, the earth is moving with the coming rumble... the REDSUNS are here....^^

Last night was a blast... 3 touge machines dishing it out, uhhh although actually only 2 that is playing cat & mouse while the other.... THE MOTHER OF ALL BODY ROLL.... THE SAGA BLM!!!!!!!!!!! OMG xD

We had a new addition to our family member with the initiation of our best pal... Kona, he bought a Proton Satria Neo 1.6 M/T by trading in a brand new Honda City!!! O.o such commitment and waste xD ahhh... the vanity of the touge >.< He calls his Neo the Hidari Olenge!!!!! which literally means "Left Orange" O.o Yeah weird name, but he have his reason which you can see on his blog here.

We started the trip a little late... a little past midnight because Keisuke and I had an appointment with an old friend... then we went to fetch Cloud and he said he wanted to drive his BLM, cool then...
BLM n FC

But the journey to Mantin was one heck of a long journey, Cloud was driving so slow I almost fell asleep following behind him >.< Kona who started off from PD where he work arrived earlier than us at the touge and waited beside the grave... he seems to have some kind of creepy thoughts and waiting beside a grave doesn't help xD so he move and waited at the main road xD When we arrived we saw nobody there... so we gave him a call then voila! The Hidari Olenge arrives!!!! ^^ Hidari Olenge
Hidari Olenge behind
They let the Flying Circus leads on the sweeping run so off we went, the loyal dog was still loyal at his usual hairpin xD and there was some water running across a dangerous hairpin, besides that the sweeping run ended uneventful as also my leading run, although I was quite impress with Hidari Olenge being able to keep up throughout the touge, although I did not push the FC because it was too dark and I was not familiar with the touge >.< Other than a slight oversteer at one hairpin corner, the mouse and cat game ended as quickly as it began, I was just warming up but Kona said he is running out of fuel so he cannot make a second run T.T So Cloud and Kona went ahead to the Petronas Station just a few km from the touge, and Keisuke and I went ahead for some solo run, I was just too scared to push the car through unfamiliar and dark road... so my run was rather unfulfilling >.< But when it comes to Keisuke, he was literally mad... ever since the Flying Circus changed its suspension and made all those repairs this was literally the first time he drove it on the touge... and he was like a mad dog!! O.o He literally dive into a corner overshot and then power over drift all the way through the exit... almost spun, almost hit a wall you name it... he almost did everything!!!! >.< His run was really exciting, the sensation of power over drift... the jumping of the heart when he immediately press the throttle... it was the like car on fire... and I was just wishing when is it going to end? >.< Hahaha... yeah, its been so long I haven't ride shotgun with anyone on the touge I have become a wimp >.< Anyway, Keisuke and I went for just one solo run each... then we head for the Petronas station rendezvous with Cloud and Kona, then we thought of hitting the Bangi Touge and wrap up our night at PutraJaya at our usual bridge^^ BLM n FC at Bank
So we went to KFC Kajang to stock on our food supply and off we went to Bangi Touge, by the time we were at Bangi it was around 3 am... surprisingly the touge is quite empty.... its just one of those lucky nights^^

After our sweeping run, Keisuke leads while Kona chase with Cloud trying to keep up with the Battle Gears at the back^^

Keisuke was driving like the madman that he is, coupled with the tyre's of the FC heating up and started to slide at almost all the corners... since Bangi consist of only medium and fast speed corners Keisuke immediately made a gap with Kona who is trying hard to keep up with me as shotgun almost half dead T.T

As the first run ended, Keisuke and Kona switch places and off we go again... with Cloud in the background again >.< This time I was riding shotgun with Keisuke, and the car was literally at its grip edge... with Keisuke shoving his nose up Kona's behind it was an exhilarating experience ;-) It was damn fun!!!! With more tyre screeches and lots of steering correction the 2nd run ended in fire!!!!^^ Next was my turn... hehehehe, Bangi is my home ground^^ I remember every hook and nook of this course like the back of my hand, I can push the limit even with limited visibility^^ and literally I did... At the first run, I dive into the MINT corner in the 3rd gear and was way faster than normal speed... the car started to oversteer midway through, I just thought instead of making a steering correction to override the slide... lets try to make a drift through the corner... so I let the car slide some more, next thing I know was that my counter-steer was too slow, the car was inevitable going into a spin xD OMG!!! I spun again at the same corner!!! xD luckily Kona was able to predict that my entry speed was too fast and he avoided hitting me^^ With Cloud arriving after the smoke has settled down^^ I quickly make a 180 to correct the car's direction and off we went again, this time I control the slide, and I was on fire... the car was twitching left and right and I was literally muscling the car through the corner with what grip I have^^ It was damn fun.... and I never did any run as fast as that, apparently Kona got hold up by Cloud's BLM so he immediately disappeared from my rear view mirror, word was Cloud was using the full racing line preventing Kona from making any overtaking maneuver :-p I decided to wait for them at the new traffic light right in the middle of the touge :-O then during the long straight Kona overtook Cloud and off we went again, but I was still on fire mood so after a few corners I lost Kona again but heck we were almost at the end anyway^^ We waited for Cloud to reach the end point and then off we went again for our 2nd run with Kona and me switching place^^ This time I'm the cat with Kona being the mouse^^ it was exiting to be chasing someone on the touge^^ we overtook a couple of civilian cars and ended the 2nd run on blazing hot trail^^ HO and FC

By the time we finished all those high adrenaline action, it was already 4 am... it was getting far too late, and Kona decided to head back home, skipping our usual 'lepak' at the bridge.... so we decided to finish the KFC at Kona's home but when we arrived at the Petronas station Bukit Mahkota, it was close... and Cloud was running low on fuel... so he said he does not want to take any risk and headed back home early T.T

Kona, Keisuke and I finished up the KFC at his home and then we headed back home as well.... since the FC is too loud around the neighborhood I decided to head to the mosque and sleep the night there so that I don't wake up any neighbors ^^
So Keisuke agreed to follow suit and we slept at UPM mosque at 4:50 am O.o
After 1 hour of sleep, I was sweating in the car xD and then we prayed and head back home in the morning^^

That was an exhilarating night, unforgettable... and almost full RedSuns crew... minus Turbo Jr who was on a date >.<

Hopefully with the FC back at full health and my holiday is still long way from over, we might be making these kind of touge frenzies more often until the end of the year^^

But until next time^^ peace....

The Flying Circus is back in town!!!!

After a week of absence finally the Flying Circus is back...
(By the way, the Shirui Suisei now has a second official nickname... the FLYING CIRCUS!!!! xD due to its new colour theme^^ based on the Air Division of the German Ace Baron Von Ritchtofen who is also known as the Red Baron during World War 1 ;-)

Apparently last week we were having some "FUN" time with the car, donuts and 180!!!^^
But after that we notice there was a leak from the engine bay, at first it look like water and we thought the car was spitting water from the radiator again... and I thought, oh boy... there goes the engine's water seals >.< Then after some few more rounds of fun I checked the liquid that is leaking under the car and it was OIL!!!! O.o OMG!!!!! The engine oil is leaking... and fast!!!! That quickly cut our fun time short xD I quickly took the car back to our house and halfway through the oil level warning pops up O.o When we reached our house and I checked the oil level it was near to Low level T.T I thought we blew a gasket or something because there were some few moments during the fun time that we accidentally over rev the engine T.T Then I had to go back to Kemaman for some official work for a week, all throughout the week I was just having my thoughts on the Flying Circus.... I thought I had blew the car T.T Then when I came back, had to draw some cash from the Petrol Rebate xD and then towed the FC to the workshop.... luckily the tow truck man still remembers me and my home ^^ hahahhhahaha he seem to have gotten use to towing the Flying Circus xD At the workshop I explained what had happen and they check the oil level was completely dry.... so Hau (our trusted mechaninc^^) gave a thorough check of the engine and found the leak to be at the oil cooler hose.... fuh, that was a relief^^ Photobucket

After changing the hose and top up with some oil treatment and of course engine oil the Flying Circus is back to life^^

Hahahahahahha... finally the nights of fire is calling us again... Touge here we come!!!^^

And here's a cool pic of a beautiful FD parked at the workshop...

And a track car FC, looks like a killer^^ wonder when it will finish^^

Karting in Rain is fun!!! ^^

YEAH!!! Finally my course here in France is over.... and everytime its over that means only one thing.... Go-Karting!!!! ^^

Hehehehe.... and it was a great time to Go-Kart as well, Autumn always brings freezing rain... and today was no exception...

I mentioned in the previous post about my previous Go-Kart experience here in the dry, and the Go-Kart grip level was not very much desirable... good for drifting, but hard for time attack...

And now in the rain.... the day before one of my friend played the Go-Kart in the rain and he warn how low the grip level can be... he was literally spinning all around the circuit, and they make us wear funny Pentium like clothes xD

So I was cautious... the day was freezing and when the Go-Kart officials started our Karts I noticed that they tune up the instructors Kart... probably to make sure he wins... or probably just my negative suspicion xD

Anyway, during the familiarization of the track... I was the only one to spun since everyone was driving slowly while I was just trying to assess the grip limit of the Kart... and its low... very low :(

And when they released us for the qualifying laps I was trying to push and assess the limits of the Kart... experimenting on lines and braking & throttle techniques... and I found that the Kart understeer badly at the entry and oversteer happy at the exits....

The tyres locks too easily and spin out of grip too fast... the grip level was really bad... I even spun at straightaways after a hard braking... a 360 spin but was able to recover without running off track...

Before the end of the qualifying times I was able to make a clean lap and scored myself a pole position... 3 seconds faster than my instructor who is 2nd^^
Photobucket

hehehe... in the rain it's more about skills xD

I found out that I need to be gentle on the brake at the entry and progressively braking hard until the entry where I let the back end locks for a moment to make a quick turn and initiate a drift... and stabbing the throttle to control my grip level and make sure my drift angle is small and neutral counter steer for maximum exit speed....

I need to constantly stab the throttle because the Go-Kart Throttle paddle setting is to put power immediately or none at all... it was hard to progressively control the throttle like Micheal Schumacher xD

Anyway, when the race started I got off to a clean start and slowly building up a healthy lead... until the last series of corners where I notice everyone behind me spun at the corners because before it was a long straightaway and everyone seem to have misjudge the braking point and miss the late apex xD

After that it was safe cruising for me... I was a healthy 30 seconds ahead even up to the point I almost lost concentration and accidentally drift the Kart... luckily I was able to catch it and it was the wake up call for me...

I started to push hard and started to catch up to the back enders^^ hehehehe.... with some fancy overtaking maneuver and avoiding spinning Karters xD I was able to lap everyone on the track up to the no.3rd guy^^

There was this one moment where I was about to lap 2 back enders battling for position.... I was able to exit the corner faster and caught up to them on the straights.... as I positioned myself on the outside to take the next corner I noticed I have just miss the braking point.... SHIT!!! I started to brake while trying to maneuver to the inside.... I had to avoid the apex to avoid hitting the guy in front of me... and ended up understeering into the corner... I started to lock the brakes to make the car turn and catch the back before I spun... a couple of locks and catches and I was able to make through the corner and pass the 2 back enders^^

Photobucket
In the end I ended the race with my 2 instructors 2nd and 3rd respectively^^ Although it was quite a haphazard to race in the rain with almost everyone spinning in the circuit but all in all it was entertaining and it thought me a lot about adapting to the grip limit of the Kart^^ lalalalala~~~~

Below is the time result of our race^^ I was number 25 ;)

Shiro Suisei updated

This is for Ryosuke who's at Kemaman working his butt off.. X-D here's the new pics of shiro suisei bro.. :-) with all the new added accessories.. :-p



The front left side-molding... :-p notice the colour contrast.. X-p





The left skirting... Notice the skirting at the front fender is also different than the skirting's colour.. :-p i didn't took any pictures, but there are some decals on the front fender, endless and yokohama.. X-p



The left rear side-molding...


The rear view.. those lights are finally ours :-p we're not borrowing it from Hau anymore... notice that the number plate is a little bit different... Hau had placed a Mark 5 plate housing replacing the previous one... if you don't like it, we can always change it back.. :-p




The missing right rear side-molding..



The front right side-molding..



The right skirting and side molding...




The new "old" bucket seat... :-p





The interior...




The cockpit with the new meters... I placed a chamois cloth at the foot area to absorb all the water contained there... X-p



The new meters...



This is the top right corner of the engine bay (passenger side), the arrows shows the water flow..



The water flows into the engine bay...



Into the hole...




This is where the water drips into the cabin... that is the wire to the meter...



The engine bay..



Notice the sensor wire for the meter... :-)

Well, that's it for the shiro suisei... i'll probably be bringing it to hau next week to get that leaking problem fixed.. i'll try to get the roadtax renewed this week :-p

Managing understeers...

Ok, this is an interesting discussion i found while browsing through touge king's vast archive... :-p here's what they have to say about managing understeers... (copied it from the comments at touge king's blog at http://tougeking.blogspot.com/2008/05/lessons-for-us-touge-crash-for-others.html)

Anonymous said...

"Its not the fault of "understeer".

Undesteer is the product of the issue of the driver misjudging thier entry speed and the traction they have.Yanking the handbrake will NOT help if you already have too much speed. You will just throw the car into a 4 wheel slide and off the road.

In fact, i do not recommend it. If you understeer, usually you'd be better off just to hit the amco barrier. putting the car into a 4 wheel slide might cause it to flip... and not mentioning trying to correct for the e-brake induced oversteer might result in an even more dangerous snap oversteer.

Imagine this, you have no front grip. locking the rear will cause the rear to not have grip as well. If you do not have enough lateral force when you pull the ebrake, you are not going to be able to rotate.

So it depends, but from experience, usually it wont work. Handbrake induced oversteer only works very late into the turn, which means you are already generating significant lateral force for it to rotate.

In order for that to happen in the first place, you need to have enough front end grip to get there. As for camber settings, tail happy FWDs are fine if you are quick enough to correct for snap oversteer or oversteer on braking. Bottom line, you'd still be stuck in a craphole if you go in too fast.

Try this the next time you understeer. turn your wheel back to centre and trail brake in (to transfer weight to the front). Then when the front starts to bite, only then you start to turn again.This is the proper way we all learnt at track school and it works.

The logic behind this method, is that a car understeers when the front slip angle exceeds the available lateral traction of your tyres. Trying to reduce the slip angle will restore front traction. Most people make the mistake of doing the opposite. Most will instictively turn even more during an understeer event only leads to more slip angle and even less grip.

Notice some of them were at full lock and car wont turn? So for FWD drivers....Better start showing up at advance track school to learn these techniques..... hehehe

Han once asks how I could maintain such a high constant grip thoughtout a turn. This is because driving smoothly allows the car to settle on its suspension and maintain constant grip. Turning too quickly leads to excessive front slip angle and cause understeer. Braking too late is also an issue as you already know about the "traction circle".

"I agree with what JC and erm said. My car has no ABS as well (plus i don't think that I like ABS at all - LOL).

adjusting the steering back to it's centerline and trail braking is another way to get back the traction on the front end before we have to turn again. After all it still rely on the speed before entering the corner, weight shifting, steering works and throttle control. This is actually has become my habits during touge sessions - Seriously i dunno wether it's a good thing or bad. (please light me up guys).

I have one video of me understeered in bukit tinggi downhill. it was a kind of high speed turn and my car speed was at around 120 - 130 km/h. I correct the understeer using my 'self thought' reflection and thank god i am safe. The speed drops from there to 60-70 km/h and i have to kick up again..

I will post the video soon.please help me light my way guys as understeer is a nightmare to most driver and the worse part of it, most of the time it occurs, it is unpredictable... "

"Interesting discussion :)!

Jeremy's advice:"turn your wheel back to centre and trail brake in (to transfer weight to the front). Then when the front starts to bite, only then you start to turn again."

This is very good IF you have a wide run-off. That's the proper thing to do for understeer correction.

However, on the touge, when there is very little run-off, there is no time for weight transfer.

Bottom-line, don't over speed into a corner...God bless us all!"

So hopefully with that we all can avoid an untimely demise at the bottom of some dark ravenous abyss... X-p ARRGH!! The FC's in the workshop again T.T can't wait for the engine swap to be done with X-) gotta get some real touge dosage... X-)

Double-Clutching down-shifting

Again i'm slacking off and no one's bothered anyway... >.> market is going south, there's hardly any activity... :-p haha... good for me, bad for the country though... X-p So here's another interesting article i found at http://www.koniaris.com/auto/blip/ written by the same writer :-) and i'd still go for the "racer's" technique of heel-toe... X-p because it's just so much more cooler... X-p haha...
Though this is just common knowledge among advanced drivers :-) it's always good to have a revision once in a while... X-)

"The Double-Declutching Gas-Blipping Downshift

The manual transmission was the best transmission that a car could have until 1989, when English driver Nigel Mansell won the Brazilian Grand Prix Formula 1 race with his SMG-equipped Ferrari. From the driver's perspective, the SMG, or "Sequential Manual Gearbox," is clutchless: Your right finger makes the car go up a gear, and your left finger makes the car go down a gear! A modern SMG, like BMW's "SMG II," shifts in about 80ms, less than a tenth of a second! No human is able to shift so fast.

Not to be confused with some automatic transmissions that have a similar user interface (the "tiptronic" from Porsche comes to mind), real SMGs can be found on the 2001 Ferrari 360 Modena ("F1") and the 2002 BMW M3, for example. Before long, the SMG will trickle down further, and the manual transmission will become the second-best choice for many street cars, certainly at the high-end.

And if this was not bad enough, both the manual and the SMG are going to be ultimately replaced by the CVT, or "Continuously Variable Transmission," which behaves as if it has infinite gears, with a computer constantly adjusting them for optimal power delivery! (In other words, even the little up/down buttons of the SMG will become totally irrelevant.)

So, what is to be gained on your part by lots of frustrating practice to learn proper downshifting for the obsolete manual transmission? "Fun," in a word! Good downshifting will bring a smile to your face. And, unlike serious grin-inducing activities like smoking the rear tires and power oversteer in turns, proper downshifting is legal and can be done anywhere and everywhere: Even in full view of a police officer with your mom sitting in the passenger seat next to you!
PROS:
  • masterful technique is always to be admired
  • car has excellent stability on ice, etc.
  • shifts can be very fast
  • engine is not subject to impulsive "hit" when clutch is let up (as in ordinary downshifting)
  • the "blip" (stab of the gas) makes beautiful "music"
  • something fun to do in ordinary traffic
  • separate yourself from the masses who don't "get it" but still drive a manual
CONS:
  • other people will hear the blip and think you want to race them
We'll break the recipe for downshifting into steps after a brief introduction.
Note that the way that you upshift is probably fine---we will only look at how one downshifts, which is different and more subtle than how one upshifts.

Introduction

A car's engine operates in a range of RPMs that typically range from about 1000 to 7000 revolutions per minute. (Some cars go up to 18,000 RPM, but the're hooked up to SMGs and cost millions of dollars.)

You typically pick an "operating range" where you want to run the car, say between 2k and 4k for most situations, and up to 7k every now and then. You could take the car up to the "red line" all the time, but the motor will not last as long, so this is something to consider for vehicles that are not leased.

When you're getting close to your (say) self-imposed 4k (upper) limit, you upshift, i.e., go to the next higher gear; when you get close to your self-imposed 2k (lower) limit, you downshift, i.e., go to the next lower gear. Sometimes you might wish to downshift at a higher RPM because you want to aggressively pass other vehicles, but make sure that you know what you're doing---such downshifting can DESTROY YOUR ENGINE by taking it above the "red line." Even if your car has a governor, it will be unable to stop downshift-induced overreving, and the resulting destruction of your valves.

Note: Sometimes drivers downshift at higher RPMs and then promptly (but smoothly!) let off the gas pedal to "engine brake." The "engine brake" technique only slows the driven wheels. So, on a rear-wheel drive car, for example, "engine braking" behaves (in terms of dynamics) as if one is pulling the parking brake! In most cases one does not want asymmetrical braking, and the brake pedal provides the optimal slowing/stopping technique, but there is one wonderful exception that Daniel Eberli points out to me (via email): When one lives in Switzerland and is descending alpine roads, even the very best brakes can get very hot and fail... and in cases like this one should certainly downshift for "engine braking" well before their brakes fail from overheating!

Recipe

Let's define some notation to save space:
G = gas pedal
C = clutch pedal
B = brake pedal
L = left foot
R = right foot
"R/G" is read, "right foot on gas."
"R\G" is read, "right foot off gas."

0. Context


You're driving with R/G. You decide to slow down, and gently take R\G, and then put R/B. As you brake, the RPMs of the car start to fall into the lower range of interest, and then you decide that it is time to downshift to the next lower gear. NOTE YOUR RIGHT FOOT WILL STILL BE ON THE BRAKE FOR ALL OF THE FOLLOWING STEPS (in most cases):

1. Setup


L goes on top of C, ready to press down, as your right hand leaves the wheel and grabs the shift lever.
2. Out of gear (shift into N)


At the same time: L/C, and you pull the shift lever into the "neutral" gear, N. Then, go (very fast) L\C. View this as having shifted into N.

3. Blip


(If you must wait for some reason before you wish to go into gear, at step #4, now is the time, at the start of step #3.) Stab the gas pedal----we'll explain how shortly---to run the engine RPMs up to slightly above the value that they will assume when you will be done with the shift. This "stabbing" of the pedal is just momentary---do it as fast as you can, on-then-off. (The moment that you blip, you must quickly move to the next step---if you fail, retry #3, or just move the clutch [up: L/C] slowly in step #4.) DO NOT TAKE YOUR FOOT OFF THE BRAKE IN ORDER TO GIVE THE GAS IN THIS STEP.

4. In to gear (shift out of N)
Go (very fast) L/C. Then, at the same time: L\C, and you push the shift lever into the lower gear. View this as having shifted from N into your final (lower) gear.



5. Cleanup


Put your hand back on the wheel, and put L on the "dead pedal" (footrest to the left of the clutch).

So, you realize that this can be thought of as shifting fully into neutral, stabbing the gas, and then shifting fully into the lower gear.

Incorrect downshifting, what you probably do now, is L/C, shift to the lower gear, and then L\C. To grow and improve, try #1-2-4-5 intil you do it without thinking. Then, go all the way, and try #1-2-3-4-5, which is a bit tougher.

If you want to drop (say) two gears in a row, go #1-2-3-4-wait-2-3-4-5 or #1-2-3-4-5-wait-1-2-3-4-5, depending on how long you're willing to keep your right hand off the wheel. Never initiate a downshift if the RPM value is too high, or you will destroy your engine. In the case of dropping multiple gears, it seems that real racers prefer to go #1-2-wait-3-4-5, shifting directly into the final gear, but you'll have to read their books yourself to see what you really wish to do in this case. Remember, skipping gears invites over-revving, which can destroy the car, but their incredible training keeps them from making mistakes---you're better off experimenting with skipping gears later when you really know what you're doing.

If you do everything right, it will take you perhaps a second or two to drop one gear (from when your hands first leave and then return to the wheel), but take your time as you work up to speed. If you mess up the blip---and this is very common when you start to learn how to do this---you can retry step #3 repeatedly (i.e., go #1-2-3-3-3-3-4-5), or just take your time (several seconds) to let the clutch up slowly in step #4. However, if you do everything right, you can be very aggressive with clutch operation, and the car will feel perfectly smooth---after all, this is the goal. If you take too long between #3 and #4, the engine will lose the rotations that you gave with the blip, so the shift will be incorrect, and you must let the clutch up slowly (in step #4). If you don't blip enough, or wait too long between #3 and #4, you'll see the tachometer suddenly jump up as you release the clutch, which means that you have to keep working on good technique.

You should not have to ram anything into place with arm strength---when you get it right, you'll feel it, and a big grin will show up on your face. (Although after a while it might become old hat, I suppose.) This can be a very frustrating technique to learn, so don't try if you're tired or annoyed. I only say this for completeness, but you should clearly not hear any grinding noises, either!

Stabbing the Gas: Athletic issues with the right foot
Now I can address the gas issue in further detail. The recipe requires stabbing the gas pedal for a moment---how can one do that? There are all kinds of ways that are proposed to do this, and they all require R to manipulate G and B at the same time. In other words, R is solidly on B, and then it stabs G for a moment to provide the "blip." R never leaves B---it continues to brake, but somehow also hits G.



There are many methods (called "heel-toe") to describe how various experts do this trick. I've never been able to make any of their tricks work, but my trick is extremely simple, and it works quite well, but only in street cars. So, check out the way that I do it, the way that they do it, and try to figure out what is best for you. I describe both methods here, but be sure to check out the literature on racing and your friends who drive for advice.

"Heel-Toe," what most experts suggest


If you're driving a state-of-the-art technological masterpiece like a F1 car, apparently you use the left foot exclusively for the brake, the right foot exclusively for the gas, and index fingers to shift, and gas blipping is totally irrelevant! However, most racers still have a manual transmission, only because of their lack of money. Therefore, gas blipping is still relevant for many racers, at least for a few more years.

Real race cars don't have power-boosted braking, and they tend to use their brakes with extreme pressure---what most civilians like me would view as a "panic emergency stop," in terms of the sensation. So, they have to brake with the ball of their foot, i.e., the area under the toes is firmly pressing the pedal.

The most commonly suggested recipe from professional drivers is to brake with the entire ball of the foot, rotate the foot on the axis of brake pedal, hit the gas with the heel/side, and then rotate the entire foot back, but I find this to be quite dangerous---I've had my foot repeatedly slip off the brake! Try this in a parking lot for a while with your car off and see if you can do it... I can't.

"My" Technique
Unlike the race car, the street car has power-assisted brakes with ABS (Anti-lock Braking System), since it even has to work for small and weak customers. This means that you do not have to press nearly as hard to get the brakes to fully lock, where the ABS decides to turn on and stop you at maximum speed.



Therefore, unlike the racers, it is probably not necessary, at least for a person of my leg strength or greater, to need much leverage to maximize brake pressure. So, I take full advantage of this fact, and am willing to blip in a way that will not work in an inexpensive (non-SMG) race car.

If your car is not set up properly, somebody else's technique must be used. In short, B and G must be about under 2.5" away from each other, and when you brake hard B should still be above G. If this is not the case, what I'm about to propose will not work, and don't even try it.

I plant the heel of my foot on a point midway between B and G, and it never moves when I drive. This is a very comfortable position for me, since the foot can rest to the right and operate G, but a slight movement of the toes will put the left half of my foot over the brake. So, I brake with the left half of my foot. BE VERY CAREFUL BRAKING WITH JUST THE LEFT HALF OF YOUR FOOT. I am strong enough to easily provide maximum pressure needed to stop the car, but my car has power-assisted braking. If this is not the case for you, forget about it!

In fact, this is so dangerous at first that you should take it very easy and practice FAR AWAY from anything that you might hit.

Brake with the left half of the right foot, keeping the weight on the big toe's base, and slightly lifting the little toe. If you don't lift the little toe, sometimes you might accidentally be giving the car gas while you're trying to brake---something somewhat counterproductive, to put it mildly. When it comes time to "stab" the gas pedal, "roll" your foot to the side, so the contact area on the brake goes from just your big toe, to perhaps half of your toes, and then just the middle line of your shoe---the small toe at this point will be stabbing the gas. Then, the foot rolls back, returning braking pressure to the big toe. (You might want to move your knee to the right and back to reduce pressure on it.)

Final pieces of advice....

THE BRAKE PRESSURE SHOULD NOT DIMINISH BECAUSE YOU BLIP---it is just that different parts of your foot provide the brake pressure for that moment that you have to stab the gas.

Downshifting is subtle to learn in terms of just how hard to stab the gas, but this will come to you in time. However, you must be EXTREMELY CAREFUL with how you apply the brake during the blip---don't let your foot slip off, or an accident could result.

After a while, your right foot will "memorize" what to do, and everything will be automatic. But as you first learn, be VERY careful, as this is an extremely dangerous time. Leave a huge following distance between you and other cars, or, better yet, only try it at very quiet times and initiate your stop well before that light, so you can recover from a huge mistake. Better yet, try it in an empty parking lot for a while. Ideally, you can help your foot memorize its operation by working the pedals in a parking lot, with the engine off. You can learn how to do this yourself, but BE VERY CAREFUL NOT TO LET YOUR FOOT SLIP OFF THE BRAKE."

Steering Techniques

Haha... Suddenly i have too much free time... >.> so here i am at it again... :-p i've said before that i'd be posting some tips on driving ^^ so here's an interesting article i found at http://www.koniaris.com/auto/steering/ about the various techniques involved in steering :-) enjoy the reading (since it's a really ReALLY LONG article.. :-p) and happy driving ^^
Steering a Car or Truck

Racing cars with special steering ratios and the like are outside the scope of this article or my fund of knowledge, and only street cars (yes, that includes your Porsche) and trucks are considered.

Proper steering encourages fast driving, since one can place a vehicle with precision and provide smooth inputs (a secret for speed). Proper steering also encourages safe driving, since one can avoid obstacles, retain control, and protect their arms/hands from airbag and steering wheel-related injuries.

While most people do not view an airbag as a bomb right next to their hands, this is exactly what it is. If an airbag deploys when your arms or hands are in close proximity, you could suffer severe injuries that might include broken bones. You really don't want the air bag to hit you as it is inflating---you want to hit the fully deployed air bag.

(A note to people who race: If you take your fixed 9-and-3 grip on the wheel of a street car, and are turning with your arms crossed, what do you think will happen if you should be involved in an accident involving airbag deployment? I suspect that you probably want to leave racing techniques for the track! That said, you know more than enough to decide for yourself, but remember that your race car does not have an airbag, unlike your street car, so perhaps they have to be steered differently.)

If your car hits a curb, deep pothole, or rock at an angle, and your thumbs are wrapped around the inside of the wheel, they can be broken due to the resulting violent rotation of the wheel, since the wheel's spokes can break your bones. This is relatively rare on the street, but easy to do if you are into off-road driving---keep those thumbs and fingers away from the inside of the wheel! Instead, pinch the wheel between fingers and thumbs using your forearm strength. Yes, it feels strange at first, but will become a good habit.

Steering is unbelievably important in so many regards, both for speed and safety, and yet few people give even a moment's thought beyond what they were told by their high-school driver education teacher. (If one thinks back to the quality of their high-school instruction, this should be cause for fear.)

One spends years of their life behind the wheel of a car (divide 100k miles by 45 miles per hour, and multiply by how many cars you'll own to determine your hours behind the wheel). Isn't it stupid to spend years doing something that you can dramatically improve with fifteen minutes of thought?

General Observations on Steering

If you're going at a reasonable speed on a flat surface, your car wants to go straight. If you "wind" the wheel (turn it away from center), the car will try to "unwind" the wheel (return it to center). Whenever possible, you should let the car unwind the wheel on your behalf. If the car wants to unwind the wheel too rapidly, you can use a little bit of friction with both hands and have it unwind at the correct rate. So, you only need hand motion to wind the wheel, and not to unwind it.

Unwinding the wheel requires two hands to provide friction because you are less likely to let go of the wheel by accident for a moment.

Techniques of Steering

There are many ways to manage the steering wheel of a car or truck, including palming, hand-over-hand, and shuffle steering. While no technique is perfect, shuffle steering is the most flexible and useful of the above three, and it is quite easy to master! When you switch to shuffle steering the quality of your driving will noticeably improve, and your more attentive passengers will comment about the car's smooth and uniform feel that is devoid of annoying little jerky movements while turning. In particular, note that most highway turns are arcs of constant radius, so if you select the correct steering input when you enter, no further adjustment is required until your exit.

While you should learn how to shuffle steer, TAKE IT EASY AND LEARN AT LOW SPEEDS IN SAFE PLACES. You should start at your desk and think about taking some turns and move your hands in front of you, getting used to the movements.

Note: It is common to discuss a steering wheel as a clock face. So, when one says "10 and 2," they mean that the left hand is where the hour hand points to 10 o'clock , and the right hand is where the hour hands points to 2 o'clock.

"Palming" the Wheel
Palming is a one-handed steering technique. Many people "palm" the wheel, where they press their open hand on the wheel and turn it as needed. In very old cars there was even a knob put on the wheel that enabled it to be easily turned with one hand! (I suppose that this knob must have been removed when people learned that hitting such a knob in an accident is probably very unpleasant.)



Palming works very poorly if complex steering input is required; try it on a slalom course if you get the chance, as I guarantee that your hand will slip off the wheel and you will lose control of the car and hit a cone or two. (If the driver's hand slips off the wheel it is difficult to recover control of the vehicle---and this can lead to accidents.) Palming barely works on sports cars (due to their stiffer steering). Finally, palming places your steering arm in danger of being broken in an accident due to air bag deployment: For example, if you are steering with your left hand at 3 o'clock and the airbag deploys, you might suffer a broken arm. (The symmetrical case holds for right-handed steering at 9 o'clock, of course.)

The advantage of palming is that one can drive any car with power steering while leaving the other hand free to hold coffee or a Big Mac, and this can be useful. But is it worth it to risk one's safety just to enjoy fast food in the car? I think not, particularly since I've never figured out how to dip chicken McNuggets while driving.

Don't fall into the error of thinking, "I'll stop palming the moment that an accident is about to happen," since if people had this much time to reason, accidents just wouldn't happen. If you must palm, at least get prepared to drop that giant diet coke so you can grab the wheel with two hands, and don't waste precious moments trying to put it down inside the beverage holder; you're better off having the inside of your car cleaned than sending it to a body shop for a month.

Hand-over-Hand


Hand-over-hand is (usually) a two-handed technique where the arms can sometimes be crossed. For example, there can be moments where the right hand is at 10 and the left hand is at 2. This technique is a total disaster, since an airbag deployment at moments like this may leave both of your arms broken. Furthermore, if complex steering inputs are required, the arms can get very confused and be placed in such a way that it takes considerable time to figure out how to manipulate the wheel. Inputs from this technique are often very jerky, and a car prefers smooth steering inputs. It is difficult to appreciate how ugly and clumsy this technique is until you watch people flail at the wheel during a slalom course.

Hand-over-hand also tends to result in an improper grip of the wheel, where the thumb is wrapped around the inside, and this puts the thumb at risk if the car should slide into a curb, for example. Hand-over-hand also has the unfortunate property that only one hand is actually gripping the wheel at many times, as the second hand is going through the air avoiding the first one. So, while this looks like a two-handed technique, it frequently isn't. Maximum confusion often results when one wants to change the direction of turning when one hand is on the wheel and the other is in the air trying to cross over the former, and these kinds of delays are never desirable, particularly if you're in an emergency.

Shuffle Steering


"Shuffle steering" is a simple technique for managing the steering wheel of an automobile or truck. This technique enables you to have full control of the steering input without ever getting confused, and you can seamlessly go from delicate corrections to big motions (U-turns or parallel parking) with ease. Happily, if your steering needs are even more advanced---let's say that you attend Bobby Ore's incredible stunt driving school---he will force you to use his own unique (more constrained) version of shuffle steering (discussed further on this very web page), as he does not tolerate the alternatives (palming or hand-over-hand).

In short, your left hand always stays on the left half of the wheel. Your right hand always stays on the right half of the wheel. So, the highest your hands can go is where both hands are at 12 o'clock (your hands touch their index fingers together). The lowest both hands can go is 6 o'clock (where your hands touch their pinkies together).

Note that the left hand is nearly always in position to operate the signal stalk (turn signals, etc.)! And should you be driving a state-of-the-art car with a sequential manual gearbox with steering column-mounted shifting paddles (a Ferrari 360 "F1"), your left and right hands will always be in position to change gears!

A hand can either grip the wheel or gently touch the wheel. If you move the wheel under a hand that is gently touching the wheel you should hear the quiet sound of the wheel's leather sliding against skin. If you were looking at a photograph of somebody shuffle steering, you would be unable to tell the difference between gripping and touching, as they look the same. (You could only tell by watching a video of the wheel turning.) Your hands never leave contact with the wheel. If the wheel is stationary, both hands are gripping. If the wheel is moving, one hand is gripping (the one that is turning the wheel), and the other hand is sliding, although you should "unwind" the wheel by relaxing both grips. If the wheel is stationary you can change the height of your grip (say from 11 and 1 to 9 and 3) by quickly relaxing and sliding the left hand and then doing the same with the right (or the converse, of course).

Your thumb is on the top of the wheel, pinching it between your fingers on the other side.

There is general shuffle steering, and a more restricted version invented by Bobby Ore, and they differ in minor details. I will describe both techniques, and you should choose your favorite version (or just use both as you see fit). I personally use the Ore version of shuffle steering because it is so elegant.

There is an excellent reference on shuffle steering by Tim Moser that seems to be reprinted in several web sites, and I strongly recommend that you read it; one instance is at http://www.racingschools.com/rs/Steering-p-29.html. Moser also talks about seating positions, etc.

(Ordinary) Shuffle Steering

When you turn right, it is because your right hand is pulling down on the wheel. When you turn left, it is because your left hand is pulling down on the wheel. This pulling down comes from your back muscles, and is therefore very powerful. So, if you're going to take a right turn, slide your right hand up the wheel, grip, and then start pulling down. If you "run out of wheel" (the right hand hit edge of its legal range of motion [6 o'clock]), the left hand can grab the wheel to keep it from turning, and you slide the right hand up, grab the wheel again, relax the left, and then continue pulling down with the right.

If you want, you can continue the right-hand turns by pushing up with your left hand on the wheel (while the right hand slides), and this will be somewhat faster, as you will not have the slight delay in waiting for your right hand to slide up the wheel and start pulling down again.

So in ordinary shuffle steering your hands can be in various positions on their respective sides, and you can slide the hands around to adjust where they rest. In general, when you anticipate a right-hand turn, you would slide the right hand up (say to 2 or 1) in order to get a good grip, and then you would turn. You could leave your left hand down near 6 to pull up to continue the turn, or you might leave it at 9 to hold the wheel so the right hand can go up near the top and pull further.

(Bobby Ore) Shuffle Steering
Bobby Ore has developed the ultimate steering technique, a variation of shuffle steering. In short, he adds one constraint, both hands must always be at the same height. In other words, here are some "legal" positions (given the left and then the right hand):


  • 12 and 12 (index fingers touching)
  • 11 and 1
  • 10 and 2
  • 9 and 3
  • 8 and 4 (the suggested default grip)
  • 7 and 5
  • 6 and 6 (pinky fingers touching)

Note that if you know where one hand is, you know where the other hand is.

So think of this more like raising and lowering your hands, where they are at the same height. The only exception to this same height rule would be when you are adjusting the height of your hands without turning the wheel because you feel like doing so.

Mild right-hand turn

Let's say that your right hand is at 3 o'clock. (This means that your left hand is at 9 o'clock.) You want to turn right. You relax the grip on your left hand and the right hand pulls the wheel down to 5 o'clock. (This means that your left hand slides down to 7 o'clock at the same time.) You grip with both hands again.

Mild right-hand turn
As an alternative to the above, you could raise your hands, but grip with the left (only). Lifting your hands is harder than lowering your hands (as you are being powered by weak shoulders vs. a strong back), but this works as well.

Strong left hand turn

You would pull down with the left hand. If you ran out of wheel (both hands hit 6 o'clock), you would continue the turn by moving both hands up while pushing with the right.

U-Turn (on left)

You would pull down with the left hand all the way until 6 o'clock, and then push up with the right hand all the way to 12 o'clock, and then pull back down with the left hand until 6 o'clock, etc. Remember to let the car unwind the wheel for you. You can do this faster than hand-over-hand with a bit of practice. Remember that with the Ore system both hands must always follow each other at the same height.

How I take a right turn in practice....

My hands will be resting at 7 and 5, gripping the wheel. As the turn comes up, I push up with my left hand (right follows), and then pull down with my right hand (left follows), and the car will start to turn, with my hands already back at the rest position. When the turn is nearly completed, I relax my grip and the wheel moves through my fingers (returning to center), with no hand motion, and then I grip the wheel again.

Note that you are always free to break a large movement up into two half movements: A large push (with the left hand, for example) can be a half push (left) followed by a half pull (right); similarly, a large pull can be a half pull followed by a half push. Two half movements have the property that your hands go back to where they were, e.g., back to the rest position, and the concept behind Ore's symmetrical hand movement starts to shine.

HAPPY AND SAFE DRIVING! :)
Note: it should be noted that the 8 and 4 position is highly controversial as some says it's more dangerous than the 10/2 or 9/3... here's a website that discusses its safety hazards...

Interesting clips

Yeah I'm bored again, and when I'm bored I surf the vast archive of YouTube.... xD
You'll never know what kind of new clips you can stumble upon there^^

And here are a couple of racing clips that really satiate my longing for my FC T.T
A Best Motoring race between RE AMEMIYA RX-7, Yoshio Factory S15 and Aqua Impreze at Ebisu Circuit, Orido and Akira displays amazing racing skills in the race as their battle really heated up in the middle of the race^^ enjoy..


And here is another clip that is worth noting, a revival of the famous Midnight Club!!?? O.o
Well none of them mention of being a member of the Midnight Club, its just the title of the video mention it xD
but man their cars really burns the Wangan xD

Steering Timing

Ok, I haven't written anything for a long~~ time, mostly because there's no more activities (since Ryosuke is gone) and because I got tonnes of work piled on me... X-p

But I guess I can't run away from slacking off, whether by writing this blog post or taking a nap on the toilet bowl... X-p work has just got to wait.. :-p

Well, this post is not about any activity, more like an information supply.. X-p

Just wanted to talk about steering correction, the thing that we failed that led to the massive accident damage on 'Shiro Suisei' :-p Paul Brand, a Star Tribune journalist got this to say about skiding and steering correction :-)

"A car oversteers because of the "yaw" generated by the rear tires sliding while the front tires are still gripping the pavement. The vehicle is effectively a pendulum pivoting around a vertical axis through the center of the front axle. There are only two key issues to saving a slide like this -- steer the same direction as the back end is sliding, and make the steering correction right now!

Little actual correction of the wheel is optimal, but only if the steering is corrected virtually instantly. The key to this is the eyes -- look where you need the car to go, not where it's going. Because the hands naturally follow the eyes, by looking in the direction the car is sliding, the hands tend to make the right correction.

Sadly, inattention, distraction, lack of understanding, inexperience and panic tend to delay the driver's recognition, processing and response to the slide. This allows the slide to increase in angle, meaning the front tires are no longer pointed where the car is headed, and once the correction is begun, more steering input is necessary (because of the increase in the angle of the car).

Now, if the steering correction is properly dialed in, the pendulum effect begins to slow. If there's enough traction available from the pavement, the rear tires will finally stop sliding, and the vehicle is at the limit of the yaw/slide and ready to snap back in the opposite direction. In performance driving vernacular, the energy built up in the rear springs unloads as the tires regain grip, initiating the "second reaction" hook slide. This occurs because the driver does not recognize the pause of the pendulum and the impending second reaction, and the back end snaps back in the opposite direction while the steering is still corrected in the direction of the initial slide. The instant the rear of the vehicle begins to swing back in the opposite direction, the front tires are no longer pointed where the vehicle needs to go -- thus the start of the back-and-forth "fishtailing," or, in the racing world, "death wiggle."

To prevent this, the three steps necessary to save a rear-end slide are 'correct, pause, recover' -- or C-P-R in the motoring world. Steer into the slide just enough instantly, anticipate the pause as the back end rotation begins to slow, and continue to look where you need the vehicle to go. Prepare to steer back in the other direction at the same moment the back end begins to snap back. Timed correctly, C-P-R keeps the vehicle traveling in the same direction it originally was before the back-end sliding.

Thus, there's really no such thing as "overcorrecting." It's more of a delay in initial steering input, then a delay or lack of recovery -- turning the steering back toward the center/neutral position as the back end snaps back. It gives the appearance of overcorrecting because the front wheels, as the car snaps back, are still turned in the original direction of the skid. But it's because of the delay in recognizing and responding to the second reaction, not because the wheel was turned too much initially.

One final key point. In terms of how much steering correction to input, this is entirely dependent upon two things: How quickly the correction occurs, and how rapidly the pendulum or back end is rotating around. There are wimpy little slides on dry pavement that require only small corrections, but then there is the "mother of all slides" at higher speeds or on wet pavement that requires every bit of available steering wheel input/angle to keep the front wheels pointed where the vehicle is sliding. This is why the "shuffle steering" technique is so important. It doesn't matter how quickly the steering correction is done -- if the steering isn't turned far enough to keep the front wheels pointed where the vehicle is sliding, the back end is never going to pause, giving the driver a chance to recover.

The last words on this issue: What if you don't "catch" the slide? In racing terms, "if you spin, both feet in," meaning lock the brakes hard instantly and keep them locked until the vehicle comes to a complete stop, and if it's a manual transmission, push the clutch in to keep the engine running. This slows the vehicle as rapidly as possible and keeps the vehicle traveling in a straight line, hopefully right down the middle of the road, as it spins." --Paul Brand--

Apparently, what occured to us was the "mother-of-all" slides plus the "second reaction" hook slide X-p a deadly combination... Zid was able to correct the intial slide, but failed to anticipate the 'second reaction' and the force the rear throws back at us that sent us spinning like a drunken bumble-bee... X-p

Well, hope we've learnt a lesson from that, and improve on our pathetic skills X-p haha...
(I'll be posting more tips on advanced driving whenever I feel like slacking off again.. X-p or when I'm not sneaking away to the toilet for a nap... X-p hoho...)

Oilfield joke

Okay, now I'm getting really bored...
I guess writing our blog post during office hour is in our family's blood...

Keisuke likes to do it, my brother likes to do it... and now have influenced me T.T
OMG I have sold my soul..... xD

Anyway, now this post is waaaaaaaaayy off our usual post, this has nothing to do with the Shuzoku RedSuns, but just a funny joke that's worth sharing^^

It's about a preacher, he have a son name Jimmy.... and Jimmy just like any other teenagers don't have any idea of what he wanted to do when he grows up... so his father the Preacher intends to find out...

One day when Jimmy was at school, the preacher went into his room and place 4 items on his desk... these items are : a Bible, a $10 note, a bottle of wine and copy of the latest Playboy magazine^^

And then he hid behind the door and wait patiently for his son's return, he figured that if his son were to pick up the Bible, then he would be a preacher... just like his father, o what blessing that will be...

If he were to pick the $10 note, then he would be a business man... o how fortunate that would be for the family...

If he were to choose the bottle of wine, then he would be a no good drunkard... and if he were to take the Playboy magazine then he would only be one of those skirt chasing bum....

Then Jimmy came back and into his room, his father hiding behind the door anxiously to see what his son will choose.... Jimmy puts down his bag, and as he heads out of his room he notice the items on his table...

He then grabs the bible and slip it under his armpit, took the $10 and drops it into his pocket... uncork the wine and enjoys the magazine centerfold ^^

"Dear Lord have mercy", his father thought.... "he is going into the oilfield" xD

The best of F1

Yeah.... I just got bored again xD

So in my boredom I browse through lots and lots of YouTube video, and stumble upon my old passion.... F1

My very first passion of racing started in 1999 during the inaugural Sepang F1 Grand Prix, and the image of Micheal Schumacher blazing the track was unforgettable...

Obviously Micheal Schumacher is my favourite F1 heroes, but there are those in history that deserve respect... and none more deserve respect than the late Ayrton Senna.

Senna was involved in the development of the Honda NSX Type-R, which is why the car is considered to be one of the best handling cars of its time... notice how he controlled his drift through the corners, incredible racing drift technique^^

And here is one of the saddest moment in F1 history, the San Marino Grand Prix of 1994, 2 drivers died in that race,Roland Ratzenberger during practice and Ayrton Senna during the race T.T


After I started getting the drift fever, F1 started to lose its appeal to me... and eventually I lost interest in it due to the fact that several rules and regulation that was really outrageous were made to dent Ferrari dominance, some of it was so dumb that they were applied only for several races and a couple of seasons, and now the sport have turned from a sprinting race to more of a marathon... T.T

But after learning all the racing techniques and theories, F1 is once again the epitome of speed and car control techniques in my view... of course after looking back the old clips in YouTube xD

And Micheal Schumacher is one heck of a driver, some may say that his dominance was because there was no real rivals to challenge him and that his driving was without soul and he's fast just because Ferrari is fast etc, etc...

They can make all kind of excuses, but Ferrari didn't become dominant by chance... and Micheal stack all those World Title not because there was no real rivals, simply because he was so far ahead of the rest... people can criticize him for driving without soul or winning just because Ferrari is fast, try to look back during the days when Ferrari was a back end team when he first joined it, or when he was with Benetton, even in 2000 when he won his 3rd world titles, his Ferrari was slower than Hakkinen's McLaren by almost 10km/h on the straights... he was just simply fast.

Mind you, I don't mean any disrespect for Hakkinen... he was obviously a fast driver... so fast that after he retired, no one could actually mount a sustained title challenge to Schumacher... I have all my respect to Hakkinen, and to all the F1 drivers in the world... they are truly a cut above the rest

Just as Jackie Stewart say : The transformation of the Ferrari team was Schumacher's greatest feat ^^

Here are some interesting clips I dug out from YouTube about the man^^ :



Waaa!!! So much more to learn about driving... these drivers are simply amazing!!!

And as a tribute to Micheal, here is a clip of his last race at Interlagos where his performance was classified in the press as "heroic", an "utterly breath-taking drive", and a "performance that ... sums up his career"
