That was a very generous dyno.

My stock A4 1997 camaro z28 with magnaflow catback, and opti with plugs/wires put down 246 so I guess I am about where the M6's are. I would guess 260ish.

Dyno it and let us know...Every car is going to be a little bit different but I'd have to say around 260 maybe close to 270, you need to get some Long Tubes, better exhaust system, heads and cam and then you will see some good numbers.

Default dyno

where I live, a shop just installed a dynojet x1year, 150bones just to put up on the dyno, no wide band!

thanks for the info fellas. after this thread I realized these mods are not making me as fast as I thought id be

i think 4.10s will be next so I enjoy more of what i got

Good luck and let us know!

take a look at the mods in other peoples sigs. keep up with this section of the forum for awhile and you will see trends in the parts people pick, but for good reason. you will hear the complaints, if any, of certain part choices as well. when it comes to exhaust on an lt1 LT's are going to get the vote, for instance.

my 97 Z28 made 276 rwhp and 317 lbs. with a CAI, 1LE and, Air Foil so my guess would be close to that.
