The 2011 Ford Mustang already packs a plentiful 412 horsepower under it’s well-contoured hood, but for some enthusiasts there is no such thing as enough power. And what makes owning a Mustang so great is that there are countless ways to upgrade your ride. Roush has done it’s fair share of Mustang modifying, and that trend continues for 2011. The new 5XR is Jack and the gang’s latest stab at ‘Stang perfection, with a R2300 ROUSHcharger mated to Ford’s already potent 5.0-liter V8 to produce a hearty 525 ponies and 465 pound-feet of torque.

When Roush upgrades a Mustang, obviously it starts with a more powerful engine, but the fun usually doesn’t end there. The 5XR will also feature a bevy of upgraded components, including a suspension kit with new front shocks and rear springs and front and rear stabilizer bars. Power will be transferred to the road via 20-inch chrome wheels wrapped with high-performance Cooper RS3 tires.

On the outside, Roush provides plenty of cues to alert even the novice that the 5XR is no run-of-the-mill pony car. Upgrades include a new front fascia with splitter, side rocker splitters, rear valance and three-piece deck lid spoiler. And if that isn’t enough to clue you in, the 5XR also comes standard with a copious amount of badging.

The 5XR is limited to a production run of 150 units, but prospective owners will first have to purchase their own 2011 Mustang. Roush-certified Ford dealers will install the $15,390 worth of goodies. Other available upgrades are up-rated vented brakes, custom leather seating surfaces and a vent pod gauge. Hit the jump to pour over the Roush press release.
