The ROUSH Phase 2 supercharger upgrade kit builds on the outstanding performance of our Phase 1 supercharger system by adding proven core components and careful calibration, for an additional 57 horsepower and 65 lb-ft of torque over our 670 hp/ 545 lb-ft system (PN 421823). The result is an outstanding 727 hp / 610 lb-ft of torque while retaining the daily confidence you expect from the engineering of ROUSH Performance. ROUSH engineers spend hundreds of hours in the laboratory, on the dyno, and out in the field to ensure the components and calibration deliver consistent performance in all conditions. The upgrade installs easily with a preset plug and play fuel pump controller, colder heat range spark plugs, and a higher boost 80 mm supercharger pulley. A ROUSH Diagnostic Tool (RDT) reflash voucher is in the box, and your upgraded Phase 2 calibration can be downloaded to your ECU in minutes by your dealer. Included in the Kit: Fuel pump controller, 80mm Supercharger Pulley, (8) NGK Spark Plugs and, RDT Reflash Voucher and Warranty. Note: This kit comes with an extended parts warranty (ROUSH Supplied Parts Only), which is good for 3 years or 36,000 miles from the date of retail purchase. Note: If this system is installed on a 2015-17 ROUSH Stage 3 Mustang, the vehicle's powertrain warranty will be voided.

Forced Induction

Forced Induction

Forced induction is the fastest way to add real power to an engine without adding displacement, and this collection covers the full range of turbocharger, supercharger, intercooler, and boost control hardware needed to build a reliable boosted platform. Whether you are running a factory turbo upgrade, swapping to a bigger frame turbocharger, adding a centrifugal or roots style supercharger, or dialing in a nitrous system for a quick shot of extra power, you will find the components here to build and support the setup correctly. Every part in this collection is organized by system type so you can move from a stock turbocharger to a properly supported forced induction build in one place. Intercoolers, wastegates, blow off valves, boost controllers, and water meth injection components are all included alongside the core turbo and supercharger hardware so the entire boost system can be sourced together. What This Category Covers This collection includes turbochargers, turbo kits, s...

Forced Induction Components

Forced induction component upgrades address the individual hardware elements within a turbocharger or supercharger system rather than replacing the entire forced induction assembly, allowing targeted improvements to intercooler efficiency, boost control precision, charge pipe sealing, oil delivery, and thermal management that collectively maximize the performance and reliability of the installed system. Many production turbocharged vehicles leave significant performance on the table with factory hardware that includes undersized intercooler cores, restrictive intercooler piping with flexible rubber couplers prone to boost leaks, and basic boost controllers that cannot maintain consistent pressure under varying conditions. Addressing these components individually with quality aftermarket alternatives provides measurable power and reliability gains, particularly on higher-mileage vehicles where factory rubber components have begun to show age-related deterioration. This collection cov...
