In May 2008, one of Revenge Designs' valued clients who had already purchased a Revenge GTO put in a order for our new Revenge Designs Signature Series with the all new Harrop Engineering 122 Supercharger and huge brake packages. As shown by our before and after dyno charts. Please note this was an Automatic transmission 2006 GTO.
Before at the rear wheels it produced 311.5 HP. Followed by the installation of the Harrop Engineering 122 Supercharger and our performance exhaust system, this vehicle produced a staggering 501.5 Hp at the rear wheels. Calculate a 18/20% drive train reduction, flywheel numbers calculate to approximately 601.8 Horsepower also providing outstanding drivability and significant fuel economy. |
