First off, my mod list for these pulls:
-218/218 on a 112LSA (see cam spec sheet for details)
-FTRA, K&N, Whisper lid, !MAF screen
-Pacesetter coated headers, !CAT, and cutout
-SPEC stage 3
-3.42's and limited slip
Previous best (only difference being the headers and !CAT) was 187.9rwhp, and at the time we were unable to get a torque reading. Tonight we dyno'd for grins, and it pulled 211.8rwhp and 221.0rwtq at about 5400rpm. So the Pacesetter headers and ditching the cat netted about 24rwhp! I never expected to see that kind of gains from these mods alone! I guss it's safe to say more of a stock car wouldn't see as big of gains. But Pacesetter still has my stamp of approval, I'm all grins [img]graemlins/rofl.gif[/img]
Wideband O2 said I was at about 14.2 A/F, but we didn't plug in the MAFT tonight to richen it up any. Can't wait to get it back on the dyno with the spray and a "mini tune"!
But it was neat to see this setup peak well before 6000rpm's. Several people have sworn against this cam saying you can't take advantage of its entire powerband with a stock rev limiter [img]smile.gif[/img] But now we all know this cam's real powerband instead of its theoretical one.
