2011-2014 Ford Mustang 5.0 V8 Roush Supercharger (Phase 2 625 HP)

2011-2014 Ford Mustang GT 5.0 V8 Roush Performance Supercharger (Phase 2 625 HP Calibrated) 5.0L 4v engine (excludes BOSS 302)

Developed in conjunction with Ford Racing, this phase 2 Roush Performance Supercharger kit will turn your Mustang into a monster. After installation, your Mustang will produce 625 Horsepower / 525 ft-lbs. torque. The Roush R2300 TVS supercharger is a roots-type positive displacement supercharger that features twin four-lobe rotors that are twisted 160-degrees. By comparison, the original Eaton supercharger rotating assembly featured three lobes twisted 60-degrees. The fourth lobe and the added twist, when combined with newly-redesigned air inlet and outlet ports, provides a long list of benefits including: 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 engineÆs entire power band.

Your Phase 2 SuperCharger Kit is a complete kit and will come with:
Roush/Ford Racing 2.3L TVS Supercharger
85mm supercharger overdrive pulley
Custom designed, heavy-duty first sheave FEAD system
60mm dual bore throttle body
Low restriction air induction system
High flow fuel rail with 47lb injectors
High-efficiency intercooler system featuring large full-face low-temp radiator, oversized coolant degas bottle, high-capacity air-to-water intercooler, and formed hoses with abrasion-resistant sleeves.
