Hey mate, When I was still racing my sportivo at hillclimbs, I used to launch it at around 5000rpm, but that was with semi-slicks on the front. after doing a burnout too, so they were reasonably warm. There is a really fine line between a nice smooth take off, and outrageous wheelspin. It takes a lot of practice, and your left foot has to be really sensitive. As for holding v tapping, i think its more a personal thing. I rev the car continuously but dont hold it at that level, just up down up down. Heres a link to a video so you can see my start (well hear it anyway) http://au.toyotaownersclub.com/forums/inde...showtopic=12968
