Mustang GT Roush Phase 2 Supercharger Kit
Drastically increase the power output of your 2018-2021 Mustang GT with this Roush Phase 2 supercharger kit! Roush's dedication to performance is fully displayed with this supercharger kit that produces 750 horsepower and 670 lb-ft of torque, a powerful 290 horsepower, and 250 ft-lb of torque increase over the stock engine! The Phase 2 kit includes all of the premium components found on the Phase 1 kit but recalibrates the tune to increase power output by 50 horsepower and 60 ft-lb of torque over the Phase 1 kit. All of this is optimized for 93-octane fuel for superior performance with pump gas, backed by a 3-year/36,000-mile Roush limited powertrain warranty, and is 50-state street legal.

High-Performance Design
This kit features Eaton's R2650 rotating assembly paired with high-flowing front inlet and outlet ports to significantly improve thermal and volumetric efficiency throughout the entire RPM range! The twin four-lobe rotors on the supercharger are designed with 170 degrees of twist for improved noise and vibration damper and offer a smoother airflow to the engine for optimum performance gains! Roush-designed upper and lower aluminum intake manifolds are included with a new fuel-charging assembly for a hassle-free connection. All-new pressure relief ports in the bearing plate provide reduced input power, and a heavy-duty first-sheave FEAD system puts less stress on the engine.
