these questions are hard to answer go to the track and see for yourself. as far as horsepower take the hp increase numbers given by the company divide by 3 and then add them together to get a rough estimate

I would have to guess high 13's with rwhp aroung 250. 250 RWHP may be pushing it a bit, depends ont he dyno you use, a dynojet will give you 245-250 RWHP, but those #'s tend to be inflated a bit.

you people need to pick a dyno. you complain about mustang dyno's giving low numbers and you complain about dynojets giving high numbers

My guess is you could see mid 13's, get some gears and you'll see low 13's.
