Me and a few buddies went out to the local dyno shop today since the owner was giving a sort of "group buy" on some dyno pulls. It was my HPF M3, 2 stg 3 B5 S4's, a 06 body style A4 2.0T (chipped, test pipe), and a UR S4 (5cyl turbo audi)
These runs were on a AWD mustang dyno so dsc light trick or GT1 tool needed to make the car work on the dyno, but I guess these dynos do read lower than a 2WD dyno like a dynojet.
I think my pump only (91 octane)numbers were kinda low but I only ran it twice on pump gas. The first run with pump onlyhe tried it in 2wd mode (but front wheels still spinning) and it said something like 2XX whp, so he flipped it into AWD mode and it read more accurate. The vids show the real numbers but i think they were something like pump only-400whp, pump & meth-550 & 563 whp.
The silver stage 3 B5 S4 put down around 380 awhp / 430 awtq with 91 octane a few gallons of 100 octane.
The Blue stage 3 B5 S4 made 400 awhp / 430 awtq on 100 octane.
It was real hot in that litttle building and the audi guys #'s were really fluctuating.
Here are a few vids.
