2014 Callaway Corvette SC627 Makes 627 HP, 610 LB-FT

Motor Trend logo Motor Trend 7/9/2014 Jason Udy

Official power figures for the 2014 Callaway Corvette have been revealed. The supercharged Callaway Corvette makes 627 hp at 6400 rpm and 610 lb-ft of torque at 4400 rpm -- gains of 167 hp and 145 lb-ft over the stock 2014 Chevrolet Corvette Stingray Z51.

Those ratings are based on the same SAE-certified power correction that GM and other automakers use, according to Callaway. With the standard correction, the Callaway Corvette SC627 would be rated 657 hp and 639 lb-ft. A dynamometer chart shows increases in horsepower and torque from idle to redline. Callaway notes that 500 lb-ft is available by 2200 rpm.

Callaway says the new intake manifold design makes 57 lb-ft more than the manifold for the C6. Cooling efficiency is enhanced by the intercooler system’s three discrete liquid-to-air cooling elements and by having the top of the supercharger housing stick out through the hood.

With vehicle calibration and testing completed, production of the 2014 Callaway Corvette SC627 has begun at the company’s facilities in Old Lyme, Conn., and Santa Ana, Calif. Other Callaway variants of the new C7 Corvette Stingray include the controversial Corvette AeroWagon and the race-only Corvette GT3.
