like topic says.
mods are in my comment. let me know what you think i SHOULD be gettin. Because i think my numbers are low. Might have a problem :-/

ill show my numbers later :-/

 

what cam are you running now? what cam were u running when you dynoed?
That info would help

 

same Comp Cam thats in my sig, everything in my sig was when it was dynoed

 

I'd say somewhere in the 395/380 range? what heads are u running

 

241 casting heads, off a newer camaro.

i ran 365/350 through a4 with 3.73s and stall. supposibly a4 dont dyno as high, and the 3.73s and back rims supposibly slow it down? or so im told.
i went and dynoed it again recently and dynoed 355/350 but it was a worse day as in, no air 100 degrees. I feel like i am low, is there anything that could be wrong? compresition ratio or something? or does that sound right?

 

i raced a new cts-v and beat it by about 5+ car lengths, when i slowed down at 130 if that helps

 

yeah that does seem a little low, but its more important how your car feels and actauallly runs.
I've seen cars dyno 410RWHP lose to cars that only dyno like 370RWHP. All a dyno is doing is measuring what your power is at the top end and not how it builds power on the street thorough the RPM range

 

hmm. You think there is any malfunction or anything that i might need to check? or do you think it just could be that persons dyno on that certain day kind of thing?

everytime its dynoed it gets tuned again. its funny cuz ill pull up get it dynoed and its at like 315 then do a little tuning on the comp and im at 360. kind of sounds strange to me... but i dunno.

 

That is weird a buddy of mine haad some low numbers with a big cam like yours and an auto and he found out his ported heads were flowing like crap. I mean worse than stock heads!
You mihgt wnna post this up in the dyno/tuning section and see what they have to say
