I've never run a 3-speed, but here's what I think I would do in your situation. I'd launch the car hard, then put it on the throttle stop. Have your shifter hooked to a timer which would put the car in 2nd gear shortly after the throttle stop turns on. When the car goes wide open again, I'd either have some way to put the car in 3rd based on RPM or just shift it by hand at the desired RPM.[/QUOTE]

I run a 3 speed TH400 in 9.90 and this is how I have my shifts set.
