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.
