What can I expect it to run?

If you really have 650 RWHP, you should be able to hit the 9's, assuming you can get it hooked up by the second or third peddle job :burnout:. If you have a pulse and can convert oxygen to carbon dioxide, you can run 10's with that car.

FWIW, my car probably only makes around 420-440 RWHP and it runs 10's all summer....If I had that kind of power my car would be in the VERY low 9's.
