Racers with Drag radials--Help

20 psi minimum is my guess if it's a 275/60 or something like that.

What gear you do a burnout in is really dependent on tire size and rear gear. You want about 100mph of wheel speed so figure out which gear that would be. My Dart, I did them in 3rd gear. Back up to the water but not in it. Just want wet ground. DR usually don't like force style burnouts. Get up on the tire, count to 2 or three and come out. Street driven cars with DR, hit them hard on your first burnout to get the crust off.
