Roush 2026 Mustang S650 Supercharger Kit – 810 Horsepower (422350) - 2026 Ford Mustang S650
Turn your 2026 Mustang S650 into an 810-horsepower statement with the most advanced supercharger system Roush has ever engineered. Designed for serious enthusiasts who demand extreme performance without compromise, the Roush S650 Supercharger Kit delivers brutal acceleration, track-proven consistency, and factory-level integration that simply can’t be matched.
Powered by the massive Eaton TVS R2650 supercharger and co-developed with Magnuson Superchargers, this system produces an astonishing 810 HP and 630 lb-ft of torque on 93-octane fuel. Proven to rip off sub-3-second 0–60 times and 10-second quarter-mile passes on a stock S650, this kit doesn’t just add power — it completely redefines what your Mustang is capable of.
Every component is engineered to meet Roush’s OEM-grade standards, from the advanced cooling system and high-flow fuel delivery to the precision calibration handled through Roush Diagnostic Tool software. The result is relentless, repeatable power that stays cool under load, drives like stock in daily conditions, and holds up to sustained high-RPM abuse on the track.
