The Shelby GT is coming back as a 2014 model, with an SC (supercharged) version at the top of the lineup. Introduced at the Los Angeles Auto Show, the SC will replace the GT350, production of which ends on December 31. There will be two versions of the SC, one rated at 525 hp (392 kW), the other at 624 hp (466 kW). A base model, naturally aspirated and rated at 430 hp (321 kW), also will be available.
Both superchargers are by Whipple, and the SC is street legal in 50 states, notes Shelby American. The car is based on a 2011-14 Mustang GT, supplied by the customer, and the conversion is performed at the company's facility in Las Vegas, NV.
The 624-hp SC has a claimed 0-60 mph of 3.7 s and a quarter-mile time in the mid-11 s range, said John Luft, Shelby American President.
The base engine, a 5.0-L V8, has a tuning package (primarily cold air intake and new Borla exhaust) that increases power from base 412 hp (307 kW) to 430 hp. This version includes a Barton shifter, Wilwood's Superlite four-piston front calipers and Promatrix rear rotors, a Panhard rod (track bar), 20-in wheels with BFG G-Force Comp2 tires, and Ford racing suspension with caster/camber adjustment plates.
The supercharged models switch to Wilwood six-piston front calipers, four-piston rears, and mount Michelin Supersport tires. A three-gauge lineup (turbo boost, fuel level, and oil pressure) is built into the driver's side A-pillar.
The naturally aspirated GT conversion is $15,000 and includes the fiberglass hood and other Shelby GT trim pieces, plus a billet aluminum grille shaped to improve airflow.
The supercharged SC models, which start at a $28,000 conversion price, also get an upgraded cooling system with an intercooler. The suspension is further modified with a rear Watts link, Eibach coil-over kit (front struts, rear shocks, and springs), and an Eibach sway bar.
