Product Description

Add serious power to your 2009 Mustang with this ROUSHcharger® 435 HP Kit. This Ford Mustang supercharger kit adds 135 hp and 80 lb-ft of torque at the flywheel to the 2009 Ford Mustang GT with the 4.6L, 3-valve V8 powertrain system, bringing the total power to 435 hp and 400 ft-lb. This system fits both manual and automatic Mustang's and comes complete with all necessary hardware, brackets, fasteners, and instructions (no supplemental kit required).

This Roush supercharger goes beyond simply adding power with its sleek Chrome powder coated finished, adding high-end styling to your Mustang engine bay.

The ROUSHcharger is the only Ford Mustang supercharger on the market protected by Ford's 3 year / 36,000 mile factory drivetrain warranty, or one year on ROUSH® components for vehicles already past their warranty date. This kit is also 50 state legal.

The main components of this blower kit include a ROUSH M90 Roots-style supercharger, intake manifold, air-to-water intercooler system, 73mm supercharger pulley (generating 5 PSI of boost), and high-flow fuel injectors and induction system. In addition to this hardware, the key to maximizing performance is the upgraded ROUSH PCM calibration. Includes new flash voucher card containing a single-use custom tune for your application. This kit also features the "ROUSH" logo, showing that serious performance lies within when you raise your hood.

A hidden but important feature of this system is the ROUSH® PCM calibration. ROUSH® goes to great lengths to develop calibrations for its ROUSHchargers® that provide industry-leading reliability, performance, and engine durability across the gamut of environmental and load conditions. No other competitive system has the same level of refinement. That's why ROUSH® stands behind its superchargers with an industry-leading warranty.
