06 Mustang GT 5 speed
Factory engine was 300 HP rear wheel dyno at 6500RPM got us 253 HP at the rear wheels. Put a Vortech supercharger and Flowmaster pipes on dyno got us 383 HP at the rear wheels. It's in the shop right now getting a smaller pully put on, I expect this to give me 50 to 60 more horses at the rear wheels for a total of about 430. Engine I would estimate will put out about 575 hp. Changed the rear end to 3:90. Gonna run her at the track this next weekend, I expect low 12s maybe high 11s if I put some nittos on the rear. Not planning on doing any exterior mods, I like the sleeper look. However when I pull up to a red light the whine of the supercharger kinda gives it away. LOL. What do you guys think?
