The ROUSH Phase 2 supercharger upgrade kit builds on the

outstanding performance of our 2015-2016 Phase 1

supercharger system by adding proven core components and

careful calibration, for an additional 57 horsepower and 65

lb-ft of torque over our 670 hp/ 545 lb-ft system (PN 421823).

The result is an outstanding 727 hp/610 lb-ft of torque while

retaining the daily con dense you expect from the

engineering of ROUSH Performance.
