Harrop Stage 4 | 563KW

Mustang GT Harrop Stage 4 | 563KW

The Mustang 5.0L Stage 4 upgrade starts with our trained technician fitting a the Harrop high flow cold air intake system and then Harrop's acclaimed FDFI-2650 intercooled supercharger system to vastly increase the engine's breathing capabilities. We then complete the package by fitting a set of 1 7/8" 4 into 1 headers, high flow metallic cats and a 3" stainless steel catback exhaust system to increase the engine's breathing capabilities and sound. A fuel pump upgrade and billet oil pump gears complete the package.

We then custom tune your vehicle's ECU on the dyno utilizing the latest Ford ECU tuning software to maximize power, torque and fuel efficiency. We complete the upgrade process by testing your vehicle on the road to make final adjustments, optimizing your vehicle's performance and driveability. At the end of this upgrade we will provide you with a dyno graph comparing the before and after power & torque increase the HPF upgrade has made to your vehicle.
