best RPM to launch at?

Well i usually launch at 3,200RPM what do u guys launch at and what do you suggest launching at for best take off?oh and i have 16 inch rims.

Depends on everything. Condition of the road/track...rims/tires all that crap. I honestly don't know what i've launched at before, I just kinda listen to the engine (yeah sounds corny) but for me it works.

depends on the conditions, nice dry day id say 3

Its true it depends on everything. What tranny you have, what motor, what tires, the ground that you're on, how heavy your car is, etc..

get some track time and practice......does your local track offer a test n tune night? that IMO would be your best bet as every car differs from not only the mods and drivetrain but also the driver. get some practice in and find your sweet spot :D

its best to launch high and feather the gas and clutch.
