Roush has released its ROUSHcharger kit for the new 5.0-liter Mustang after its debut at the Woodward Dream Cruise, force-feeding performance nuts with enough induction to pump the Mustang GT's output from 412 horsepower and 390 lb-ft of torque to a monstrous, semi-warrantied 550HP and "more than 470 lb-ft" of torque. What was once strictly Ford GT and GT500 power has officially become available for the M3-hunting Joe Regular GT, all at a suggested price of $5,999.
For that price, buyers get a supercharger unit with a 90-mm pulley that creates approximately seven pounds of boost, bigger injectors, new fuel rails, a new throttle body, and a higher-flowing intake lid. A specific calibration is not provided with the unit, though.
For a Roush-calibrated unit and full warranty, interested parties will have to wait until later this year. Currently Roush offers a 90-day warranty on the parts, but installing the unit will still negate Ford's engine warranty.
Jack Roush says, "while the new Ford five-liter engine offers amazing performance right from the factory, and the new ROUSHcharger will kick it up a level...Our engineering team has worked hard to deliver a product that will satisfy the demands of the ROUSH customer on an extremely tight deadline, and they have come up with another great solution for a powertrain upgrade."
If going for pure power and not worrying about paying that SVT badge premium, this might be worth a look as soon as the warrantied version comes out.
