The World’s First Twin-Turbo C8 Mid-Engine Corvette Makes 643 HP on a Dyno


First deliveries for the C8 Chevy Corvette started last week, and we’ve already seen people do a bunch of stuff with them. There’s been C8s at the drag strip, C8s with nitrous, and C8s on the dyno. Now, there’s a C8 with a twin-turbo kit. Yup, someone’s already taken the time to attached two turbos to the new Corvette’s LT2 V-8 engine.

That didn’t take long.

Texas tuner shop Hennessey Performance recently picked up its new Z51-equipped 2020 Corvette, and after doing a high-speed test run to 182 mph, went to work slapping a twin-turbo kit to the mid-mounted V-8. The company plans on offering a 1200-horsepower upgrade for the car, according to its website. Here’s what that LT2 sounds like with two snails attached.

Hennessey has been pretty mum on details, saying only that it’s retained the factory throttle body and the rear trunk’s usability. Things like turbo specs and boost levels have yet to be released. In the dyno video above, it’s able to lay down 643 horsepower and 570 lb-ft of torque to the rear wheels—an increase of 148 horsepower and 100 lb-ft of torque over the stock crank horsepower numbers, respectively. A ways off from its promised 1200-horsepower number (so far, anyway).

This is the first turbocharged C8 we’ve seen, but it certainly won’t be the last. As more shops and tuning companies get their hands on the mid-engine ‘Vette, we’re sure we’ll be seeing kits for turbos and superchargers alike pop up online in no time.
