Since it was asked how much wheelspeed is enough, my answer would be however much it takes to straighten it up. I know manual trans cars have a bit of an issue as you have to get it rolling and not kill the clutch. FWIW my current car the burnouts are 6-6500, in high gear I use a limiter to get going at 5900, once it blips that I let it rip. In this car in high gear 6500 is probably 130+ mph. Have to look at the racepak to see where that is?
