Roushcharger gets 30 horsepower bump

A few days ago Roush sent us the press release below. Looks like the "RoushCharger" supercharger system for the 2005+ Mustang GT is getting a smaller pulley and updated PCM calibration. The revisions add yet another 30hp to a total of 445hp up from the stock 300hp. Owners of previous model Roushchargers can also upgrade their model by buying a $400 kit.

LIVONIA, Mich. (October 2, 2006) - ROUSH Performance, America's leading powertrain engineering group, has added an additional 30 horsepower to their legendary ROUSHcharger* system for the Ford Mustang GT; this increases the output of this supercharger system to a total of 445 horsepower under the hood.

The additional horsepower comes from changing to a slightly smaller pulley and an enhanced PCM calibration to take advantage of the higher spin rate. Customers with a previously installed ROUSHcharger* can upgrade to this High Boost Pressure Pulley by ordering part number 402863 which has a suggested retail price of $389.00.

With the addition of the upgraded ROUSHcharger* any 2005-2008 Ford Mustang GT can be increased to 445 horsepower with 418 lb.-ft. of torque. This is a 48-percent horsepower gain over the stock engine's 300 ponies. This ROUSHcharger* system will soon be legal in all 50 states for both manual and automatic vehicles.

"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."

The ROUSHcharger* is also 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 more information, visit and search for these part numbers or look under the Mustang section of the online store.
