Okay, my car is a 1998 Z28 M6. Mods: Slp Loudmouth, Pacesetter LT's, TSP ORY, Granatelli Lid, !EGR, !AIR, FRA, Tune by PCMforless.com. What kind of RWHP could I expect? I'm going to the track soon, what kind of times should I be running? I also have a B&M ripper shifter.

Depends on the dyno.

330-340 easy.

That's my exact setup, but I have a billet flywheel & 4.10s. Everything else is the same lid, muffler (full exhaust), open cutout, tune, fresh tune-up, etc. (same parts, but by different manufacturers).

I did 313 at the wheels. Launching on the street with ET streets and a passenger I went 12.8-12.9 on a G-tech at full street trim with speakers, books, tools, etc. Also burnt my clutch up (8K mile spec stage 3) and broke my rear the same night.

Don't worry about the dyno numbers too much. The above rwhp is a SAE corrected value from Thunder Racing's chasis dyno.
