drag racing 101
I've been doing my burnout like that for 15 years and never had an issue... quick 1st to 6000 then right to 2nd and finish in 2nd or sometimes 3rd if there's a crowd in the stands.
I've heard the same story about starting in 1st but I think moper is correct... don't let off in first.... also depends on the type of sprague you have.
It doesn't matter what I do, the point is you want to have a routine and stick too it.
