While at the 2008 Shelby Meet in Oviedo, FL, we had some extra time to throw Lethal Performance's GT500 on the dyno. They had been running a mail order tune from VMP for their intake and longtube setup, with stock blower and stock pulley (for now).
With a tweak to the A/F the car made great power on the second pull. Most cars were only making 495-505 today with similar mods (intake+tune) and stock exhaust.
The LT's seem to be worth about 10-15hp, even on a stock pulley/blower car.
The LT's resulted in about 1psi of boost loss.
Next week Jared is putting a whipple on the car.
