Very true, I have also experienced the same. On a bike, its fun to negotiate an acute turn with engine braking by shifting the gear down by a gear along with rpm matching...the same doesnt hold true with a car..Any explanations why so ?

On the track on many turns i use engine braking by shifting down, works rather well.

Simple : RWD v/s FWD

You can induce a bit of locking and wheelspin on a bike. As soon as that happens, a bit of control, and you can make the bike slide in the direction you like. Lo.. your turning radius is reduced.

In a FWD, you cant make the rear hang out even if you provide oodles of torque. Try the same with a RWD car, and I think you can find the nimbleness around the corner.
As one Mr JC said, the front wheels are for steering and the rear for driving.


p.s. : I was bitten by a rabid dog and i decided to remove the rev-limiter on my Gladiator. Coupled with a port job and a free flow air passage all throughout, it gives me way too much joy to just slide around corners rather than taking the clean line. I doesnt get me there faster (obviously), but it sure is more fun. The Tbird does it easily because of the oodles of torque from the RE mill. And nope, I am yet to highside or crash out. But one day I sure will.

ye even I resort to engine braking, but its just that a bike is more fun !

I think what aqua said makes sense, RWD & FWD

s3va:
Have you tried Heel & Toe downshifting?

Guys:
I can feel the fun that you all had.
I know I missed an awesome trackday.

For selfish reasons, I would urge all of you to consider a track day sometime in Aug 2010. I will verify on track availabilty and start another thread on the same.

WOW: Nice video and a sweet motor man.. The 2nd and 3rd gears seem custom made for the track.

BTW, some action seems edited around 6:4xx ish

Sadly I did get to meet you that day though i came in a little late and saw the car go around..

What do you feel about teh mid corner bump at C1?

Thanks. The gearing is stock. I found the ratios a bit wide for a NA engine. They would do much better on a Turbo setup.

I was actually running 41psi in the tyres during my first session. Tyres were barely gripping. Borrowed a pressure guage from the guys testing the race esteem and brought it down to 35psi for my vbox stint. I later got to know from the pros that even 35 was too high for the track. They recommend 26-28psi for best results.

That bit isn't edited. The camera overheated and shut off for a while. LOL
I did a total of some 8-9 laps but only a few were recorded.

There's always next time.

A bit scary. During the later stages i had to actually take a slightly wider line to avoid the bump. They should pave that section asap. Wonder how the bikers were handling it.

I have another spectators view of the cars taking C1. Will post it later.

shan2nu, you seem to be doing some 'rev matching' while changing gears at corners. How does that help?

Rev matching at shifting down is actually good for the clutch.They do that by using the heel and toe method.
It reduces stress on the driveline and the chances of wheel lock while engine braking is reduced a lot.
The nissan 370 Z has the syncro rev gearbox which does the rev matching automatically when downshifting.

The way I resort to is as follows, which differs slightly from the Wiki explanation

1) approach the turn, calculate the spot to brake,
2) depress the clutch , shift the gear down, release the clutch while simultaneously rev matching by pressing the required throttle.
3) apply the required brakes to slow down(brakes can also be applied simultaneously as required, along with step 2, when the clutch is released post rev matched )

correct me if am wrong somewhere

IN the second step the way I see it is , rev match it then release the clutch.
Or I might be wrong. Its difficult to put it in words. Its easier to do it I guess.
