Harrop Stage 3 | 522KW

Mustang GT Stage 3 | 522KW

The Mustang 5.0L Stage 3 upgrade is expertly designed to provide substantial performance enhancements through a series of carefully selected modifications. The upgrade begins with our trained technician installing Harrop's acclaimed FDFI-2650 intercooled supercharger system, which dramatically increases the engine's airflow and performance capabilities. In conjunction with the supercharger, we fit the Harrop high-flow cold air intake system, further boosting the engine's breathing efficiency while enhancing its aggressive sound.

To optimize exhaust flow and further unlock performance, we install 1 7/8" 4-into-1 headers, significantly improving exhaust evacuation and reducing back pressure. Complementing these headers, a dual 3-inch cat-back exhaust system is added, which not only enhances exhaust flow but also delivers an exhilarating sound that perfectly embodies the spirit of a performance Mustang.

Once all modifications are in place, we proceed to conduct a custom tune of your vehicle's ECU on the dynamometer. Utilizing the latest Ford ECU tuning software, we meticulously optimize the engine's parameters to maximize power, torque, and fuel efficiency, ensuring that all upgraded components function together in perfect harmony.

The upgrade process wraps up with thorough road testing, allowing us to make any necessary final adjustments to enhance your vehicle's overall performance and drivability. At the conclusion of the upgrade, you will receive a dyno graph comparing the power and torque figures before and after the HPF upgrade, showcasing the impressive improvements achieved.

As with all HPF upgrade packages, the Stage 3 upgrade is modular, providing customers with the flexibility to incorporate additional enhancements in the future without incurring unnecessary expenses. HPF is committed to delivering maximum performance through high-quality components while ensuring that reliability and drivability are prioritized throughout the upgrade journey.
