hold rpm's at 3k. when its time to go, step on the throttle, and let go straight up on the clutch at whatever rpm you choose to launch at.
atleast thats how i do it

ive done almost every luanch method and the one i said above is proven to be the best

from what i've heard about the G-Tech, its alittle off from the real 1/4 mile times but its very exact when compairing the results to other results you've gotten on the Gtech.
so if before the new launch technique, you would get consistant 13.0s and now with the new launch technique you got a 12.65, i'd say thats a vast improvement.

actually, the gtech is more accurate then the track, but since everyone goes my the track, gtech is not considered a time to go by...
the track measures from point a to point b... based on 2 sensors, which can be triggered by debris & cause false times...
gtech measures 1/4 exactly, based on mathematical calculations and formulas, which are consisent & proven...
i used my gtech at the track and its off by .1 or .2, so i would say its very reliable!

Just bought a 2003 WRX, And i'm learning all i can. Whole New Ball game here. So to launch you need to bounce the throttle to keep boost alive? With that Silencer removed i can here it boost under hard thottle. But will i here it while im bouncing the throttle?
Thanks
Thanks

How does bouncing the throttle keep the boost up? I thought that at x RPM you would be at (aproximatly) y psi of boost. Isn't the ammount of exhaust gas made by the engine almost constant at any given RPM? Is there some other factor I don't know about. This isn't a flame, I just want to know the reason it's like that.

if ur holding at an RPM, ur not spooling up boost as high as it can... cuz of course the fasttest spool is wen u floor it...
so if ur consistently flooring it back and forth, and then floor it once more before take of... ur gonna launch at full boost at ur peak TQ... which gives 1.7 60'

You're "loading" the motor against it's own inertia. It's harder to spin up a motor that is winding down in rpm than it is to rev it up from a standstill or to hold it at a constant rpm.
