The automotive tuning world has welcomed a new gem courtesy of Roush Performance. For nearly 30 years, the Michigan-based aftermarket expert has been providing components and upgrades for Mustangs. In 2024, Roush released the S650 Mustang’s Phase 2 Supercharger Launch Edition Kit, designed to maximize the performance of Ford’s 5.0-liter Coyote V8 engine. This kit is compatible with the 2024 Ford Mustang GT and Mustang Dark Horse.
It was only a matter of time before the new Ford Mustang received wild enhancements to take its iconic V8 formula even further, especially now that the new-generation Mustang family has been rounded up with genuine beasts such as the Mustang Dark Horse or the 800-horsepower supercar Mustang GTD.
But if you don’t have $300,000 to get your hands on a GTD, you can still enjoy 800+ horsepower with this new Roush supercharger, which will only set you back $9,995. Roush co-developed the Phase 2 Supercharger with Magnuson Superchargers, bringing over 50 years of combined supercharger expertise to this kit. The result is an upgrade for your new Mustang that promises to elevate your driving experience.
Brutal Supercharged Performance
The seventh-generation Mustang, codenamed S650, unveiled in 2024, marked a continuation of Ford’s commitment to the iconic pony car. By retaining the internal combustion engine, the blue oval automaker potentially extended the lifespan of the gasoline-powered muscle car for at least another decade. This decision allowed performance enthusiasts and aftermarket tuners to push the Mustang’s limits. Independent tuner Roush has entered the fray with its Phase 2 supercharger kit, boosting Mustang output to 810 horsepower and 630 pound-feet of torque.
The heart of the 2024 Roush Mustang Phase 2 kit is an Eaton-sourced TVS R2650 (2.65-liter) supercharger. This limited edition supercharger kit boasts a dual throttle body, front inlet, front drive, dual intercooled, inverted R2650 system with an 84mm pulley, peaking at 13 PSI boost at 7,500 RPM. The revolutionary design of this new supercharger kit provides up to 34% more throttle area compared to industry competitors. Roush claims that the enhanced airflow and improved throttle response deliver a smoother, more responsive driving experience.
Roush’s Phase 2 kit delivers a substantial power boost through a combination of upgraded components. The kit incorporates high-flow fuel injectors and reinforced fuel rails to support the engine’s increased output of 810 horsepower and 630 lb-ft of torque. A dual-intercooler system is included to manage elevated air temperatures, boost, and compression generated by the supercharger and optimize engine efficiency under demanding conditions.
Roush-Supercharged Mustang vs. Dark Horse And GTD
The Ford Mustang is the last American muscle car. Unlike its muscle car rivals, the Chevrolet Camaro or the Dodge Charger and Challenger, which were all discontinued due to poor sales in the Camaro case and emission regulations for the Dodge models, the Mustang continues to reign supreme in the muscle car world in the 2020s as its sales surge and its lineup keeps growing.
The new Mustang GT retains the 5.0-liter Coyote V8 engine from the previous generation. However, this new unit is rated at 480 horsepower and 415 pound-feet of torque, compared to the last gen’s 450 and 420 pound-feet of torque. As mentioned, the S650 Mustang’s Phase 2 Supercharger Launch Edition Kit boosts the Mustang GT’s 5.0-liter V8 to 810 horses and the torque to 630 foot-pounds. The Mustang GT Fastback starts at $42,860, while the Roush supercharger kit is $9,995.
With an MSRP of $60,635, Ford’s factory-tuned Mustang Dark Horse variant serves as the performance benchmark with a more track-focused approach, delivering 500 horsepower and 418 pound-feet of torque. The street-legal, track-ready supercar 2025 Mustang GTD is positioned above both, promising over 800 horsepower, though specific torque figures remain undisclosed. The GTD will set you back $300,000. The 2024 Shelby Super Snake, limited to only 250 units, offers a whopping 830 horsepower configuration featuring a Whipple supercharger for those seeking even higher performance levels. The Shelby Super Snake costs less than half of the GTD at $140,270.
Roush’s Future Plans For The Mustang
The Roush Phase 2 supercharger kit is not currently approved in California due to the absence of a CARB Executive Order (EO) number. However, Roush hinted that this certification might be in progress by saying, “not yet.” The kit does meet SEMA emissions standards, ensuring compliance with federal regulations.
Production numbers for this limited edition are undisclosed. However, for those who may consider 810 horses excessive for their Mustang, Roush plans to launch a lower-tuned version later this year. These options will offer a more affordable entry into the high-performance world without compromising the quality and reliability for which Roush is known.
The Launch Edition Phase 2 supercharger kit includes a limited warranty covering parts—Roushe’s warranties normally span three years or 36,000 miles. While the warranty typically extends to the engine and transmission, specific coverage for the supercharger kit requires further clarification from Roush.
