I bracket race so what would be the most consistent way of launching the car.
I'm thinking like 2,500 high enough to launch hard but low enough that it isn't too hard to hold the car still.

TCI 3800, MT ET Streets 26x10.5x16, stock suspension, sway bar disconnected, a couple of bolt-ons.

TIA

 

Experiment and find out. It will vary with track conditions. When my setup was close to that (same tires, TCI SSF3500, bolt-ons) I launched from about 2500 rpm and stuck pretty consistently.
