With an auto, about the best you can do is brake torque the launch, with the tranny forced into first gear, and then slowly bump up the transmission at redline each gear without lifting off the throttle. Letting the tranmission shift on it's own will slow you down some, but so will the initial kickdown since auto transmissions like to try and launch in second or third if possible.
BTW, you know this forum is more for the twisty track guys right?
