Well, I put my hawk on the dyno yesterday at TUNE TIME PERFORMANCE in Toms River NJ. My mods are an SLP LID, HOOKER LONG TUBE OFF ROAD HEADERS AND Y-PIPE, AND 4.10 GEARS. The numbers are 322 Horse Power and 320 lb/ft Torque at the wheels. I was pretty pleased with that, and now if I could get it to turn a 12.8 I would be thrilled.
