ROUSH Performance and Ford performance have developed this industry-leading calibrated supercharger system. Boosting performance to 650 horsepower for the 2018-2020 Ford F-150 5.0L V8, the ROUSH 2.65L Phase 1 Calibrated Supercharger Kit is part of the TVS line of superchargers developed by ROUSH Performance, raising the bar for performance and reliability. 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, 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.
