Dyno numbers...good or bad?

I think stock most put out 190ish hp to the wheel. 205 is not too shabby considering that the only mod that made a difference was the prochamber.

um, actually, I beg to differ... I gained a ton of rwhp w/ my cai (off ebay too ) and I'm making a ton more hp and tq than you are... all I have done to my car are: CAI, ASP Pulleys, and O/R H w/ catback. I'm making 232.3rwhp and 293.8rwtq.

your numbers seem a bit low to me... (apparently, I have a very nice engine from ford ) but still... have you checked your A/F ratios lately? a friend was running so lean that they refused to dyno him again until it gets fixed... he should have been around 250rwhp, instead, he was around 210... so, I'd have that checked soon! you don't want to be running out of tollerence range...

sounds a little low i put down 196/273 stock

oh, wait... was that a dyno jet, or mustang dyno? that could make all the difference there...

-oh, and btw, the exhaust was not the only thing to give you power to the rear wheels... my CAI did a ton for me... and I know it does something for everyone... your aluminum driveshaft help the parasitic loss of power... but the exhaust was the largest gain... thought you might like to know

na... the exhaust leak won't "hurt" the numbers... maybe youre life (from co2 poisoning ) that is very weird then... if it were a mustang dyno, that would partially explain that... but no... there is something wrong w/ your car I'd say... have your fuel pressure checked, and your A/F ratio... that could be the problem... but w/ those mods, I'd expect you in the 220-230rwhp range, and 280+ rwtq... I made 280 torque w/ just CAI and pulleys... (also, 212 hp) and that's on a dyno jet as well...

-I wouldn't drive it hard at all until you find "something" to expain that... I wouldn't worry too much, but there has to be some reason for it...

-btw, yes, I know you have a lot of miles on your engine... but that still wouldn't fully expain the lack of gains from your mods...

-oh, and seriously, I'm not trying to flame, or brag, I'm just trying to help out your stang... and try to minimize any potential damage from running lean (a good friend was too lean, and raced... w/ very bad results I might add) so, good luck.
