The 2008 Shelby GT500 is one awesome car. Equipped with a 5.4L (330 cid) super charged intercooled DOHC V8 engine that produces 500hp at 6000 RPM and 480 lb-ft torque at 4500 RPM, this car is fast! Using a dual 60mm electronic throttle body and a supercharger operating at 9 psi of boost Shelby and SVT have created a legend.
