I hit a 14.819 1/4 mile and I haven't even touched engine internals with my NA 3800 MC SS. Did it with bolt on intake and exhaust work and I don't even have headers. Full street trim.

Here's the mods:
Corsa Catback, RT 3" DP, CC T304 PLOG, Wizaired, ZZP Offset Polys, GMPP Koni Kit, Powrtuner, ZZP HVTB, 10.4's, AL605s
