Always launch 3-400 RPM short of peak torque (let it flash) and shift 200 RPM past peak power. Also install a rev limiter that holds the car at that RPM before you launch. If using a shift light, make sure you compensate for the delay in time, from the time you see the light, to when you react to the light, and when the car actually makes the shift, and set the light accordingly. At 5 or 6000 RPM you can be 500 RPM past your shift point during that time.

Maybe because the setup is pretty standard for everyone in that class. Either air or electric shifters, cross overs,etc.

It runs hard..1.360 60's on a 10 inch tire. I once made 17 passes over a two week period and all within 9.70-9.80, so it worked for me.
