Well, I asked my boss. He has raced a little bit and went to Skip Barber racing school. Regarding using the brake and accelerator at the same time (according to him) If you have an automatic or semi-automatic (no clutch), you just don't do it. The time to do it is when the clutch is in and you need to keep the revs high so you don't stall. That's what he said, anyway. I don't think I'm going to be using a clutch in simming anytime soon - I think this means I will be OK with the Andretti wheel and pedals.. they seem to have the best out-of-the-box pedals.... I also liked the fact that they are digital. Boy, I wish I had a wheel already!! Andrew

Its called Heel and Toeing, getting the engine revs up before changing down when braking and clutching between shifts. Right foot moves from Accelerator to brake pedal, revs drop, clutch goes in with left foot, toes from right foot drift across the pedal to the accelerator to raise the revs before shifting down whilst the heel still brakes. Toes come off accelerator as soon as shift is complete. never tried it myself, but if you want to drive quickly in real life (on track anyway) you have to master it (cept in F1 where semi autos abound.) pez * Sent from RemarQ http://www.remarq.com The Internet's Discussion Network * The fastest and easiest way to search and participate in Usenet - Free!

Very good description, but when I used to do it, it was right toe on brake, right heel over to kick the accelerator. Of course it would depend on the pedal layout. Once I did it to double-clutch into non syncro-mesh first gear in an MG-B, while moving, and the owner of the car said, "How'd you do that?" I had sort of the cat-swallowed-a-canary feeling.

Hmmm.... I'm not sure I get the part about stalling, but anyway. At least in GPL and NFS:PU, I use the brake and gas to help me steer. In NFS:PU, with some cars on some tracks and at higher speeds, I find that dragging the brake with the gas still pushed helps me keep the cars attitude right and I'm more stable in the corners (sweepers). In GPL and to some extent in SCGT, I know there are times I've gone into a corer too hot and again applying the brake and gas (and playing with them) is the only thing that saves me. I can start to spin in GPL and then recover. Something I couldn't do before I used split axis and something that requires split axis to do. I also sometimes exit a corner faster by squatting the car, I get on the gas sooner but still slightly drag the brake for a short time. Since I was not sold on the benefits of split axis before I started with GPL, I did a lot of testing with and without it (basically to prove it wasn't necessary). I won't say for sure that it decreases your lap times (probably does somewhat) but it certainly makes it easier to drive and can get you out of trouble occasionally. Just something to keep in mind. On the other hand, the precision of the wheel could make you faster in GPL, even overcoming the lack of split axis. -- Slot www.slottweak.com Tweaks & Reviews "Andrew Turner" <[email hidden]> wrote in message news:[email hidden]... > Well, I asked my boss.

The bottom line is that much of the work in driving an automobile fast is that of weight management. Deceleration moves weight forward and acceleration moves weight backwards. Sometimes it is advantageous to move weight forward by using the brakes for better front-end grip while continuing to use the throttle to balance the car. This sort of thing is normally done to fine-tune to path of the vehicle through a corner. One observation I've heard and would be interested to hear others thoughts about is "When driving a race car, if you are not on the gas you better be on the brake. There's no place for coasting."

Unless, of course, you're Soap-Box Derby Racing!!!!!!! Yeah! Buddy!!! Sorry, couldn't resist. Andrew "Brett C. Cammack" wrote: > ..."When driving a race car, if you are not on the gas > you better be on the brake. There's no place for coasting."
