Why burnout? Because muscle car. Because why not. Because Roush.

Whatever your justification (if you even need one) there's always a little room in the day for some gratuitous tire smoke, especially when delivered at the drive wheels of a big American V-8 that's been tuned up to 540 horsepower.

The 2012 Stage 3 Roush Mustang gets its muscle courtesy of an R2300 Roush supercharger, which pumps 10 psi of compressed air into the 5.0-liter Coyote V-8, bringing the Mustang GT up to essentially Shelby GT500 levels without the extra 0.4 liters of displacement.

Check out the video below, and hit up Roush's website for more details on the Stage 3 kit if you're in the mood.
