Re: launching RPM
im in a stock gs and usally launch at 3000 w/feathering quickly and that seems to do well...i've only dumped a few times from around 4k but the wheel hop is hellatious!

Re: launching RPM
slowly walking the clutch out is feathering, it can burn up a clutch but gives you good launches without lots of wheel spin

Re: launching RPM
A light weight flywheel works well with this too. Having a Aftermarket performace clutch does as well. I have been very content with my centerforce dual friction, its uhh 90% over stock for the application it was for, which was not my motor to begin with =]Originally posted by papa roached:

Either way with it i can launch at 6-7k on the track without wheel hop or asstons of wheelspin.

Re: launching RPM
Ideally you want to have the motor at powerband, then feather the clutch out as quickly as possible (while trying to keep the motor in powerband) while not letting the clutch out too fast so you don't break traction. This is hard on the clutch but it keeps the traction/power ration at its best (max power while still retaining traction). Also, lightened flywheels are actually bad for launching. What happens is there isn't enough rotational inertia when you let the clutch out and the engine RPMs drop, so you have to give it the gas to add more power to keep the power/traction ratio at equilibrium - a ZE has enough power to do this but a 1.6L 4cyl does not and I doubt a K8 does either - so to reiterate, without at least a KLZE the engine's force alone is not strong enough to bring you to this power/traction equilibrium without the help of a heavier flywheel. Lightened flywheels are really made for auto-x...
