Rives Callaway established Callaway Cars in 1977. This was long after the muscle car craze wound down and high horsepower performance machines were just a thing of past. He specialized in producing turbocharger kits for installation on European cars. His knowledge, expertise and the start of the turbo era perfectly lined up, so the company took off.

To show the real potential of the twin turbo C4, Callaway produced the legendary Sledgehammer Corvette. It was a highly modified, heavily turbocharged 1988 Corvette that produced 898 HP and could go over 250 mph.
