Seems high to me. It said I was making 498 rwhp on my 11.07 run in my last car. I dynoed at 417.

I like this calculator. It gave me any extra 55rwhp that I didn't know I had.

The calculator said: 552 rwhp
The dyno said: 594 rwhp

Other calculators have said 561 rwhp. I've also calculated what my injectors would support at 100% DC at a given pressure and 550-560 seems to be in the ballpark IIRC from hartline performance's turbo buick web calc. The only difference for me was I locked the converter on the dyno and did not lock the converter at the track. That could be the 40 hp difference I'm seeing.

dead on for me 400, I would think that if its under rating you and your weight is right, then that just means theres more room for improvement, same goes if it over rated your car, better than average I guess.
