No-Prep Racing in Spokane tonight

Short burnout on drag radials (don't even drive that thing out of the garage toward a racetrack on bfg's. or cobra's)
Around 20 lbs rear tire pressure. You can play with that, but I sure wouldn't go under 15.
I would stage, bring it to a fast idle, 15-1800 or so, and stab it at the last yellow, assuming a full tree. If it spins....PEDAL IT, and just drive to the other end. And then try something different next lap. Maybe half throttle from a dead idle.
Point is... play, have fun, experiment. You have find out what works for your car, and YOU.
