Roush 2021-25 5.0L F-150 Phase 1 Supercharger Kits

Roush 2021-25 5.0L F-150 Phase 1 supercharger kits provide instant throttle response and can generate increased power through the engine's entire powerband. They utilize the 2.65L R2650 TVS supercharger, adding an additional 305 hp over stock, boosting power output to 705 hp and 635 lb.-ft. torque! As always, this power comes with peace of mind. This Roush Performance system is backed by their in-house 3-year/36,000-mile limited powertrain warranty when installed by a certified ASE technician. The roots-type positive displacement supercharger with twin 4-lobe rotors that are twisted 170 degrees offers 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. Roush supercharger kits have completed hot development trips to validate cooling performance, AC performance, and towing capability. Over 900 hours of dyno engine durability and testing were completed to validate the supercharger and meet Roush Performance's engine durability requirements. Key features and benefits: * Billet aluminum viscous crankshaft damper developed by Roush engineers to reduce the increased torsional inputs needed to handle the increased power level, improving durability and longevity of supercharger * Uniquely developed spark plugs, optimized for forced induction application * 107 percent larger LTR surface area for increased cooling (2 times larger than the previous Roush low-temperature radiator) * Retains all factory driving modes * 3-year/36,000-mile Limited Powertrain Warranty included when installed by Ford dealer or an Automotive Service Excellence-certified technician * Includes all necessary installation hardware * Roush Performance calibration included (to be downloaded using the Roush RDT software) * Calibration optimized for 93 octane fuel (premium fuel recommended, compatible with 91 octane) * Roush calibration removes the cylinder deactivation feature (Variable Displacement Engine) Show Less
