Roush R2300 Supercharger
This Roush R2300 blower features Eaton's new Twin Vortices Series technology rotating assembly that delivers more power and better fuel economy in a smaller package for uncompromising performance. By comparison, the original Eaton supercharger rotating assembly featured three lobes twisted 60 degrees. The fourth lobe and added twist, when combined with NEWLY redesigned air inlet and outlet ports, greatly enhance thermal efficiency, deliver higher volumetric capacity, enable higher operating speeds, creates a smoother, more efficient flow of air into the engine and has improved noise and vibration characteristics.

Quicker Power
Unlike turbo-charging, the ROUSH R2300 TVS supercharger provides instant throttle response and can generate increased power through the engine’s entire powerband.

- Fits 2011-2014 Ford Mustang 5.0L 4V

The supercharger kit is protected by ROUSH Parts limited warranty (ROUSH Supplied Parts Only), which is for 3 years or 36,000 miles from original installation date.
