i think till you have lots of power in the high range you would just be kicking your self in the ass keep the low end power you have so you dont have to lauch at such a high rpm. also demon hit the head on replacing your diff and get some slicks or drag radials. and the problem with slicks you would want to get them hot or you be in the same place as cutting out your exhaust your car would just die from the grip they would have.
i was just at the route 66 drag stripp for battle of the imports and the only cars cutting out with a dump tube were high powered turbos
