Burn out
At the tracks I go to, they like us to roll into the water, spin the tires there to get 'em wet and then roll out of the water. They hold us there until they cars ahead of us are out of the way and then we do the burnout.
I've got Mickey's on my car too, and you're right... get 'em too hot and I slow down a tenth or more. I spin 'em just enough to get the smoke going in 2nd gear, then shift to 3rd for a second or two, release the line lock and get off the throttle.
