i hope that a gto running right will make more hp than that. 262 is not enough in my book. my 2000z made 308 rwh even with the automatic trans my friends 02 z 6spd made 312 rwh i guess while iam test driving mine(when it gets here) ill run it over to the dyno and go from there :mad: :(

My '98 stock did 283.

the '02's were doing 310+ routinely stock and even a few ringers in the 320's. They're all over LS1Tech.com Even a fellow former co-worker who had his stock Collector Edition T/A ripped off a 325 rwhp on your dyno Jon.

Something is either wrong or someone is missing a conversion factor.

They have to correct for temp, humidity, barometric pressure, then there is an SAE correction factor.

yes also when you let off the throttle the car will lean out and give a higher # mine was 312 when i dynoed mine last the 308 was the factored in # but i was wrong it was 301 with a filter factored in and 308 factored in with a mti lid

Lane --- are we talking auto or m6?

Im JUST talking about autos. The z06 made 353RWHP bone stock...... i know these things can make power :) its just the a4 bone stock #'s that are not the best
Both, but yes, I will say that A4's do tend to be a little lower than M6's. But that amount that was churned out on this dyno. Something has to be wrong. Perhaps the parking brake is on slightly. :D

I think you may need to call the boys at Dynojet and have them fly out and recalibrate. :D Even mine seem a little low. :)

But then again I've seen many with great numbers on yours (dunno what all trans they had though).

6 of one, half dozen of another. FLP's also tends to be low. PTC seems to get higher results, can't really say with Street Stuff as I've only dyno'd there once.
