At what RPM should I launch my stock GST at the track?

[SSZero]

Hey everyone. I've taken my car to the track a few times to see how I'd run. The best time I've gotten so far with my auto GST (stock) is 16.3... I don't know about you guys, but I think that's pathetic, and I know I can do better... I need to know at what RPM it would be the best to launch at, and I'd like to know when the best time to shift would be. My buddies have told me to blow off the turbo right before redline and then shift, but I've only tried shifting while blowing off so far. I need to know what the best way to shift would be so that I get my car within the 15 or possibly high 14 second range... Help me out... Thanx...

I have no idea what your buddies are talking about. Especially since its an auto. The turbo shouldnt "blow off" at all until you finish your run.

By blow off, I mean take my foot off the accelerator, then putting my foot back down on it... O_o lol

I dont think that will make the car any faster

I'm not sure about that... Won't letting the turbo blow off relieve, then quickly reinsert pressure? Thus, making me accelerate a little better? Don't forget, manual cars do that already since you have to let go of the accelerator to switch gears. If I'm switching gears in an auto, I do believe I have to do the same, otherwise I think I might blow the turbo or my engine...

another question? how the hell are you launching it at varied RPM's?

PLEASE tell me you are not revving it and slamming it down into drive.


personally I would put it in 1, hold the brake with left foot, or instep of left foot if pedals are close enough, and when the staging lights are lit, floor it with the right foot or outside of right if doing option 2. by the time the 3 yellows went by it should be stalled a pretty good RPM, and then when the last yellow has lit slip foot over all the way to the gas or release the brake and go, then right before redline push the stick into 2, then right before redline shift up to D or however yours are numbered/lettered. none of that letting off the gas and flooring it crap, alls it does is take fractions of a second away from the time you are actually accelerating and letting out the boost only to make it have to build again (which wouldnt take long sicne the turbo stays spinning pretty damn fast but still wastes precious time) Id try it not shifting it either to see if it makes a difference, ive been in cars where it automatically shifts right at redline, my mustang shifted pretty early, and some cars ive been in upshift faster by themselves than when the driver intervenes and does it them selves, my car was one of them but I still think it was faster my way cuz I didnt fall so low in the curve even though it took a bit longer to shift

its better to hold boost, then let it go.

[SSZero]

Neutral drop, NEVER!!! I know how bad it is to do that... I just leave in low, rev to about 3000 rpms (right when the turbo spools), then let go of the gas and go... I'm going to try without shifting and without letting off the gas while I shift. It might help... But hey, with a stock GST, what's the best time that I could get?

let go of the gas? i dont think that will help. lol

[SSZero]

Oops, I meant let go of the brake...

it does that on a manual, not for the sake of "being quicker" when you hit the next gera, its so when you close the throttle plate theirs not 15 lbs+ of boost pushing against it and building tons of boost in the piping/IC cuz nowhere to go, since engines not breathing it all in.

and when you let off and floor it again, you feel it jump, but thats cuz you let off so now your not accelerating and when you stomp on it your high in the powerband where you got most your power and it pulls hard right there. and is 3k the highest stall speed you can get outta your car?

you want as much pressure goin thru the motor at all times without getting knock!

i dont blame you kevin for not posting in this thread after this post

No.

Think about it, bro...combustion relies on the amount of intake air to be powerful. That's why turbochargers make our cars so much faster. Would closing off the supply of intake air when you don't drive a manual car and need to change gears really help INCREASE performance?

Launch at like 3k rpm, hold the pedal to the floor, and break into the 15s .

[SSZero]

Thanx man... I really needed that... lol Now I'm gonna shut my friends up (they're Honda lovers bent on making me get rid of my GST. And they don't think I'll hit 14 seconds with this car. In time, though, they'll see...

[SSZero]

OH YEAH! I also forgot to ask. At around what RPM is the best time for me to shift in my auto? I'm thinking between 6500 and 7000 (redline)... I know I can't shift at 7000 since I have that delay, being that it's an auto, so when should I shift?
