Callaway Corvette 1000 HP
Rives Callaway established Callaway Cars in 1977, long after the muscle car craze had wound down. So, high horsepower performance machines were just a thing of past. He specialized in producing turbocharger kits for installation mainly in European cars. In the late ’80s, he was already a well-known name in the car industry.
Callaway concentrated on building his own creations on the bases of regular models. And at the moment, the hottest U.S. car was the Corvette C4, which delivered 245 HP. That may not seem like much, but in those days it was a respectable number. So Callaway developed a twin turbo kit for the venerable Chevrolet V8.
And at the end, the car produced a whopping 345 HP, which was an increase of 100 HP over stock. Chevrolet was so impressed by the result that it included the Callaway conversion as a regular production order. That meant customers could order the Callaway Corvette C4 from all dealerships.
But to show the real potential of 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.
