Roush Performance 422001 Phase Supercharger Kit Mustang GT - 2 727HP 2015-2017 5.0L

The Roush Performance 422001 Phase 2 Supercharger Kit transforms your 2015-2017 Ford Mustang GT 5.0L into a 727 horsepower beast. This complete TVS (Twin Vortices Series) supercharger system delivers an impressive 292 horsepower and 210 lb-ft of torque gain over stock, producing 727 hp at 6850 rpm and 610 lb-ft of torque at 5000 rpm. Compatible with both manual and automatic transmissions, this kit represents the ultimate power upgrade for S550 Mustang owners.

Complete Supercharger System:

The Phase 2 kit builds upon Roush's proven Phase 1 system with additional core components and precise calibration, adding 57 horsepower and 65 lb-ft of torque over the Phase 1 configuration. At the heart of this system is the Roush R2300 2.3L roots-type positive displacement supercharger featuring Eaton's advanced TVS technology with twin four-lobe rotors twisted 160 degrees for maximum efficiency and improved thermal management.

Key Components Included:

• R2300 2.3L TVS supercharger with 80mm high-boost pulley
• Roush-designed upper and lower aluminum intake manifolds
• Twin 60mm throttle body with matching throttle body spacer
• Complete cold air induction system with washable/reusable air filter and air dam
• High-flow fuel rail with Roush-designed fuel injectors
• Large fabricated aluminum intercooler with full-face low-temperature radiator
• High-capacity degas bottle and air-to-water intercooler
• Custom heavy-duty first sheave FEAD system
• Roush Phase 2 calibration file with exclusive Roush Diagnostic Tool (RDT)
• Preset plug-and-play fuel pump control module
• Motorcraft high-performance spark plugs (Phase 2-specific)
• All required fasteners, wiring, brackets, hoses, and clamps

Performance and Technology:

Unlike turbocharged systems, the R2300 TVS supercharger provides instant throttle response with increased power throughout the engine's entire powerband. The advanced four-lobe rotor design with 160-degree twist offers greatly enhanced thermal efficiency, higher volumetric capacity, higher operating speeds, smoother airflow, and improved noise and vibration characteristics compared to older three-lobe technology.

Warranty and Emissions:

Roush backs this supercharger kit with a comprehensive 3-year/36,000-mile limited warranty on Roush-supplied parts. The kit is 50-state emissions legal and has been granted an Executive Order by the California Air Resources Board (CARB), making it legal for sale and use in California and all states that have adopted California clean air standards.

Installation Note: Professional installation required. Kit must be installed by a shop equipped with an SAE J2534 pass-through device or Ford IDS device for proper calibration.
