Turn Your Mustang into a 750 Horsepower Machine

If you own a 2018-2021 Mustang GT and crave the kind of performance that makes your pulse race every time you touch the throttle, the Roush Phase 2 Supercharger Kit delivers exactly that. This upgrade takes the stock 5.0L Coyote V8 and boosts it to an incredible 750 horsepower and 670 lb-ft of torque, giving you nearly 300 more horses than stock. At the heart of this system is Eaton’s proven TVS R2650 supercharger technology, paired with Roush’s own calibration for smooth, predictable power delivery across the RPM range. The larger low-temperature radiator improves cooling capacity, so the extra power doesn’t fade when the engine heats up. Whether you enjoy track days, spirited weekend drives, or simply want to dominate the street, this kit transforms your Mustang into a completely different beast while maintaining factory-like drivability.

Built for Performance and Reliability

Roush didn’t just focus on raw numbers; they designed the Phase 2 kit to handle the added stress of big power with long-term reliability in mind. Large bearings, robust timing gears, and high-quality materials ensure the supercharger can withstand aggressive use without sacrificing durability. The system is compatible with both manual and automatic transmissions, and it’s fully optimized for 93-octane fuel while still working seamlessly with premium alternatives. Installation is straightforward for an experienced shop, and every component is engineered for a precise fit under the factory hood with no unnecessary modifications. Best of all, the kit comes 50-state emissions legal and includes Roush’s 3-year/36,000-mile limited powertrain warranty when installed by an ASE-certified technician. This means you can enjoy the thrill of 750 horsepower with the confidence that your investment is backed by one of the most respected names in performance engineering.
