Just recently had my car dynoe'd before and after. No scanner so no pics, sorry.
Previous hp mods: Magnaflow cat-X & cat-back, tune, 75mm tb & plenum, K&N
Before dyno run #'s= 251 rwhp, 291 rwtq.
Last year's dyno run= 252 rwhp, 296 rwtq
New mods: Slp Lt's & Slp cat-x, SLP pullies, aluminum D/S.
New #'s= 268 rwhp, 305 rwtq
No new tune was done because the A/F was close to the original run, near 13.0.
Not sure what the pullies or D/S did but the guy said not much. Maybe 3-4 hp over 4900 rpm combined he said. It was a Dyno Jet dyno. The Entire curve was 15-20 rwhp more than before, and tourqe was between 10-15. Not same day dyno but one was done a couple days before. Temps were close to the same, around 80 and low humidity. The sound is much deeper now above 2500 rpms. #'s are SAE.
