10-02-07: Roush Performance rarely stops. They rarely create a product and leave it at that. Now arguably, America's leading powertrain engineering group, Roush has added an additional 30 horsepower to their well known ROUSHcharger system for the 2005+ Ford Mustang GT. This means that adding this system to your Mustang will bring power up to an impressive 445 horsepower. This is a 48-percent horsepower gain over the stock engine's 300 ponies. This ROUSHcharger system is not yet legal in all 50 states, but Roush will soon have it approved for both manual and automatic vehicles.
Best yet, this new upgraded power rating still comes with the Roush warranty, where many supercharger systems drop their warrany coverage when the boost gets going. The additional horsepower comes from changing to a slightly smaller pulley and an enhanced PCM calibration to take advantage of the higher spin rate.
"The ROUSHcharger is one of the most thoroughly engineered and tested supercharger systems on the market," said Jack Roush. "We have several hundred engineers here at ROUSH and utilized their collective knowledge to create a powertrain upgrade that will perform better than expected each and every time you put your foot on the gas pedal. The ROUSHcharger has been tested following O.E. requirements and we are certain that it is designed to provide years of trouble-free use."
He's right. His company has resources and abilities to engineer and build OEM level products that few aftermarket manuacturer;s can touch. That expertise has allowed the ROUSHcharger to be the only supercharger unit that is protected by the industry's leading warranty which covers the balance on Ford's 3-year/36,000 mile factory drivetrain backing, or one year on ROUSH components for vehicles already beyond this level.
The main components include a ROUSH M90 Roots-style supercharger, intake manifold, air-to-water intercooler system, high-flow fuel injectors and induction system. In addition to this hardware, the key to maximizing performance is the upgraded ROUSH PCM calibration.
The ROUSHcharger is available in the standard black casing (part number 403309, suggested retail $5,599) or a polished version (part number 403310, suggested retail $5,899).

For those thousands of customers with a previously installed ROUSHcharger, they can upgrade to this High Boost Pressure Pulley by ordering part number 402863 which has a suggested retail price of $389.00.
