The 2011 Mustang GT brought about the triumphant return of the famed “5.0” Ford engine. Sure, it is now a four-valve, dual-overhead camshaft engine light years more advanced than the last pushed V8 Ford made, but that name means a lot to the Ford faithful. As it turns out. the new 5.0 is also the aftermarket’s new best friend when it comes to performance parts.
Roush is now offering a new “Phase 2” Roushcharger supercharger kit that offers the 5.0 faithful up to 625 horsepower and 525 ft-lbs of torque. That’s a lot of power right out of the box!
The timing of this move is a bit interesting, to say the least. Previous Roushcharger kits offered between 525 horsepower and 575 horsepower.. Now that the Shelby GT500 is rated at 662 horsepower for 2013, Roush is also bumping up its supercharger calibration to offer an extra 100 horsepower.
That brings the total output to 625 horsepower and 525 ft-lbs of torque. If you already have a Roushcharger Phase 1 system, then you can upgrade with a new pulley, belt, a larger intake, and new calibration. That means you don’t have to plop down a whole lot of extra cash to get that bonus horsepower.
The new Roushcharger system should help continue the great tradition of competition between Roush and Shelby owners, while offering a great performance product.
