I'm going to the track for the first time with my fox that has 17x4.5 Weld RT-S and 17x10 rears with Mickey Thompson ET Drag Radials, I need some tips on tire pressure front and rear and launch RPM. I have a two step and a line lock. The car is a 393w with a progressive nitrous setup currently jetted for 100hp, I may bump up to a 150 shot. From what I've read it's not ideal to launch while spraying, my nitrous starts spraying a 3000rpm, should I launch at 2000, 2250, 2500, 2750? The car has a HD MM torque arm and panhard setup. Any help is appreciated.
