Just taking a poll here to see who has automatics and how they prefer to launch burnouts.
For burnouts, do you ever give it gas in neutral then bring it down into drive or just brake torque it? I used to rev it up to 5000, drop to drive then get on the brake. Sort of like a clutchless manual, and it would just sit there burning the tires until you let off.
Another technique my buddies from high school would do with a 1987 Olds Cutlass Supreme with a 350 bored out, is get it rolling down a hill about 20 or 30mph, go to neutral and then floor it and put it in drive and burn the tires all the way up the hill. I never tried this but i bet it would sure be fun.
