If you have street tires they dont need heating up, set tire pressure to about 25psi, and just hold the brake and do alittle few second burnout to get any rocks or water, etc. off the tires, DO NOT drive in the waterbox, go around.
If you have drag radials or slicks, go around the water box, reverse into the water box, drive out dont go too far or the water will come off and wont spin as much, hold the brake and floor it and do a good 10 second burnout, or untill they get traction. Then line up and let them rip. I would recomend reversing into the water box, if you drive through it, you have a chance of your front tires picking up water and when you leave the line it could leave some behind for the back tires too pick up, thats what I was always told.
