Roush has announced a new supercharger for the 2018 through 2020 Mustang GT with the 5.0-liter V8. Last year the company introduced a Phase 1 supercharger that pushed the current-generation Mustang’s V8 engine to 700 horsepower. Roush has now unveiled its 2018-2020 Mustang Roush Phase 2 supercharger kit that pushes power to 750 horsepower.
The Roush Phase 2 Supercharger kit is 50-state legal and requires calibration optimized for 93 octane fuel. The kit also comes with High-Capacity Cooling Technology with a full-phase low-temperature radiator. The supercharger is compatible with both automatic and manual transmission Mustangs.
Roush says that the supercharger kit is engineered for durability with large bearings and timing gears. All necessary installation hardware is included with the kit, and it comes with a three-year/36,000 mile limited Roush powertrain warranty. The supercharger itself uses Eaton’s TVS R2650 technology to increase power output throughout the RPM band. Roush has included a dyno sheet that shows the kit pushes the Mustang GT to 750 horsepower and 670 pound-feet of torque.
That power output represents a 290 horsepower gain over the stock engine. As you might imagine, the supercharger kit is quite costly, with a price of $7,999 with free shipping included. We like that Roush includes a better radiator to help keep the car cool. Roush uses its superchargers on its factory produced Mustangs making adding this kit to your car much cheaper than purchasing a Roush Mustang at the dealership. Were also glad to see that the Phase 2 supercharger kit still maintains Roush’s limited powertrain warranty. California Mustang fans will be pleased to hear that the kit is CARB approved.
