Callaway introduces Camaro Z/28 SC652

The paint on the logo of the Chevy Camaro Z/28 isn’t even dry yet, and American tuner Callaway is already licking its chops in anticipation. The company says it can take that already-badass Z/28 and boost it to 652 hp, hence the name. To get the extra power, Callaway adds an Eaton TVS2300 supercharger to the LS7, a liquid-to-air intercooler, bigger fuel injectors, carbon injector covers, high-flow intake, low restriction exhaust, embroidered floor mats, door sill panels, badging, plaques, a Callaway key fob and a three-year, 36,000-mile warranty.
