Hey, I was wondering how I should launch my automatic, (like they do in drag racing, or in the fast and the furious, like the very last drag race, with the black car, before the light turns green, both engines get very loud, and then take off very quickly.
To do a manual I know you somehow use the clutch, but how would I go about doing that on an automatic? I've tried holding the brakes and bringing up the rpms, but then the back wheels just start spinning, and I just sit there. Should I put it in neutral then raise the rpms and put it in first? I also tried that too, and it sounded pretty funny and jerked very hard. And also, how much should I bring up the rpms? I'm getting a new engine put in my car in a couple of weeks. It's going to be a 383 with over 550hp. Thanks for the help.
