Carol Shelby has a long history with turbocharging. The man responsible for some of the quickest and most legendary metal on the planet flirted with forced induction back in the ‘80s when he hung around with the Chrysler crowd. Now it looks like 2010 Ford Mustang buyers can opt for a special Shelby turbo package. Consisting of a Turbonetics sing-tubo system, the car produces a mythic 550 horsepower from an otherwise stock 4.6-liter V8. A short throw shifter, unique grille and Borla exhaust are all part of the package, too. No word on price, but it should be substantially less expensive than the big bad GT500. [Source: Ford]
