The Roush R2300 TVS supercharger is a roots-type positive displacement supercharger that features twin four-lobe rotors twisted 160-degrees vs older three lobe, 60 degree twist technology. The fourth lobe and the added twist, when combined with newly-redesigned air inlet and outlet ports, offers greatly enhanced thermal efficiency, higher volumetric capacity, higher operating speeds, a smoother, more efficient flow of air into the engine, and improved noise and vibration characteristics. Unlike turbocharging, the Roush R2300 TVS supercharger provides instant throttle response and can generate increased power through the engine’s entire power band.

Roush developed an amazing kit using only high performance components that really set the RoushCharger apart from any other supercharger system on the market. Everything in this kit is essential to boost the performance of your 2015-2017 5.0L Mustang and become the owner of a 727hp Mustang overnight with the NEW Roush R2300 Phase 2 Supercharger kit!
