Nearly a year ago, Callaway Cars pulled the sheet off of something that’s been in the works for a very long time: a supercharged C8 Corvette Stingray. The 6.2L LT2 V8 engine is mated with a 2.3L TripleCooled supercharger, featuring an in-house design with roots-type Eaton TVS 2300 rotors. But at the time, final performance numbers weren’t revealed as the company was still running tests on the build. But now, Callaway Cars – long standing as one of the best GM performance shops in the world – has disclosed the performance specs for its supercharged C8 Corvette Stingray package.
Callaway Supercharged C8 Corvette Stingray: More Power Than A Z06, Added Mean Looks
According to Callaway, the maximum horsepower of the engine with the supercharger is 687 with 643 lb-ft of torque. This enables the C8 Corvette Stingray to accelerate from 0-60 MPH in just 2.67 seconds. For comparison, the Stingray comes standard with 495 ponies and 465 lb-ft of torque. That’s an increase of 192 horsepower and 178 lb-ft of torque. That’s even more than the C8 Corvette Z06, which has 670 horsepower and 470 lb-ft of torque.

Though pricing isn’t yet available for the C8 Corvette Stingray Supercharger, Callaway is taking $1,000 deposits if you want to get your hands on one. The package will cost around $20,000, so you could get a supercharged C8 with more power than a Z06 in the $85k- $90k range before any options.
Callaway states that this package won’t use a piggyback system to calibrate the vehicle, which could indicate that it’s either working with HP Tuners, whom recently found a way around the C8 Corvette’s encrypted engine and transmission control units. Or it could mean that GM, which has a great relationship with Callaway, worked with the Connecticut-based tuning company directly.
The supercharged C8 Callaway Corvette production was initially expected to begin in early 2023. However, seeing as we’ve passed the halfway point for the year, early fall may be a better guess. These extreme cars will be sold through Callaway’s official network of licensed Chevrolet dealers and are backed by a three-year/36,000-mile GM powertrain warranty and an optional five-year/60,000-mile service contract. This only sweetens the deal as you won’t find any other third-party company matching GM’s warranty.
