2018 Ford Mustang Roush Performance Supercharger (Phase 1 700 HP Calibrated) 50 State Street Legal.

Developed in conjunction with Ford Racing, this phase 1 Roush Performance Supercharger kit will turn your mustang into a monster. After installation, your Mustang will produce 700 Horsepower / 610 ft-lbs. torque. The Roush R2650 TVS supercharger is a roots-type positive displacement supercharger that features twin four-lobe rotors that are twisted 170-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 R2650 TVS supercharger provides instant throttle response and can generate increased power through the engine’s entire power band.

Your Phase 1 SuperCharger Kit is a complete kit and will come with:
Roush/Ford Racing 2.65L TVS Supercharger
85mm supercharger pulley
Fuel charging assembly with Roush-designed upper and lower aluminum intake manifolds
Twin 60mm throttle body and matching throttle body spacer
Low restriction air induction system
Roush-designed 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.
All required fasteners, wiring, brackets, hoses, and clamps.
