i launch my car at 3000. and i pull 2.2 60' times all day. even on my stock tires i was getting 2.2-2.3 60' times. when i had the stock tires (which was also the first 2 times i had gone to the track with it) i was launching it around 2500-2800. i shift mine just before redline. i also speed shift it. i dont power shift it because i dont feel comfortable doing it. tried it before didnt like it. it just takes a little time to learn how your car reacts when you race it on the track. also when you do your burn out, since you are on street tires you dont have to put up a cloud of smoke. do just enough of a burnout to dry them off and just warm them up a little. too much of a burnout on regular street tires can actually cause you to spin more off the line.
