Ready to Perform: The 2005-2006 Mustang GT ROUSHcharger

Las Vegas NV, November 1, 2005 – At SEMA 2005, Roush Performance Products (RPP) introduces the 4.6 liter, 3-valve Mustang ROUSHcharger for 2005-2006 Mustang GTs.

Press_must_charger RPP engineers have developed a Roots-type ROUSHcharger and companion aluminum intake manifold that generates approximately 5 psi of boost.  The package includes a large, free-flowing air-to-water intercooler used to cool and condense the ROUSHcharger’s intake air for added performance.

Additional features of the system include a larger fresh air inlet, low-restriction air filter, large diameter clean air tube, a single-belt drive system for the ROUSHcharger and all engine accessories, intercooler heat exchanger and pump, and a unique Roush supercharged calibration.

When equipped with high-flow fuel injectors and lower-heat-range spark plugs are also included in the fully integrated package, the ROUSHcharger produces 430 horsepower at 6300 rpm and 385 foot-pounds of torque at 4500 rpm on the 4.6-liter 3-valve GT V-8 engine.

As with all Roush Performance Products (RPP) powertrain offerings, the ROUSHcharger is backed by an industry-leading 3-year or 36,000 mile warranty that includes coverage on all ROUSHcharger components, as well as the vehicle’s drivetrain components, including: engine, transmission and rear axle.  The ROUSHcharger was designed for easy installation.

Roush Performance Products (RPP) is the street performance division of Roush Enterprises, parent of Roush Racing and Roush Industries.
