Re: Normal dyno? (COLORADO FRC)
There is definitely a lot of difference from one dyno to another, I've decided to always use the same one each time I do any mods. My 1999 bone stock FRC pulled 319.6 RWHP, I've since added Andy's (A&A Corvette, Andy rocks!!!) stage II heads and cam, FLP Headers, ZO6 Intake, removed the cats and added an aluminum flywheel, also changed to 3:90's which will actually rob a few RWHP. Anyhow, my new dyno (did it today!) was 393.6 RWHP. A lot of people will try to add up HP in a cumulative manner (ie. intake 10, headers 15, heads 50 so I should have another 75, just doesn't work that way, plus most HP quotes for mods are quoted at the flywheel and not RWHP).

Re: Normal dyno? (1969stingray1969)
well phills they probably rated the horsepower gain after it got tuned which i have not done yet so stop getting all annsey. I know a guy who did less than I did but put headers on but no full exhaust and he had it tuned and it came out like 322rwhp. So you would have to get it tuned. Which I am in the process of doing when I find a local tuner. Or in OKC :nono:
Your friend with headers and tuning probably picked up 20-30HP so his dyno sounds right.

I'm stock, 1999 FRC six speed. 52K miles. I dyno'd 311 HP and 317 TQ on Saturday. Check out the thread below.
My friend with a '99 Coupe dyno'd 312 HP and 325 TQ with Borla Stingers.
