Callaway Releases Performance Specs for the 2014 Callaway Corvette

While the 2014 Callaway Corvette won’t exceed the 650 horsepower of the 2015 Z06, Callaway engineers have nevertheless managed to bump their final figure to a very impressive 627 hp, up some 167 hp over the base Stingray.

Callaway Cars announced the figures this week after extensive vehicle testing and validation by its engineers, who also rated peak torque at 610 lb-ft at 4400 rpm, 145 lb-ft more than the stock LT1 produces.

On the accompanying graph, you can see Callaway’s unique, new for 2014 supercharger and single acoustic chamber exhaust system have combined to increase horsepower consistently from idle to maximum engine speed that doesn’t peak at 6000 rpm. Callaway also points out the broad torque curve, with output already exceeding 500 lb-ft (SAE) at only 2200 rpm.

Callaway’s new system offers 57 lb-ft (SAE) more than its own 2013 model, thanks to the new intake manifold design, new intercooler design, and a 2300cc high helix angle, four-lobe rotor pack.

Supercharging naturally produces more heat as it increases air pressure. If the temperature is not kept in check, it can negate the supercharger’s positive effects.

But Callaway’s new intercooler system with three discrete liquid-to-air cooling elements – along with extending the supercharger housing through the hood to dissipate heat convectively – practically eliminates this temperature increase, as witnessed repeatedly during product development testing on the dyno and at the race track.

With the final performance figures determined, Callaway has started producing Callaway Corvette SC627 models, which have already begun shipping from Callaway’s Connecticut and California plants.

One note: Callaway uses SAE certified power correction to compute horsepower and torque for its vehicles, employing the same method that Chevrolet and other vehicle manufacturers use. Using standard corrected computation for power and torque, as many aftermarket manufacturers use, the Callaway Corvette SC627 would be rated at 657 hp and 639 lb-ft of torque.

The Callaway Corvette made its debut at the 2014 Corvette Museum’s Bash. Here’s the video from the car’s introduction:
