Now that 2020 Chevy Corvette C8 manufacturing is underway – nicely, was underway in advance of almost everything shut down – proprietors are getting to enjoy the new athletics motor vehicle. It also usually means aftermarket tuning businesses can get the most up-to-date Chevy, as well, and Hennessey is one particular these kinds of shop. They’ve examined it on the dyno, added a prototype twin-turbo setup, and examined it on the dyno again – and uploaded the films, as well. Now we can view as John Hennessey gets powering the wheel to see just how nicely the turbocharged Corvette handles its new-discovered electric power
The video strictly covered John’s driving impressions, leaving any general performance number comparisons for a afterwards video. He notes that there are a couple look at engine lights aglow, but this turbocharged Corvette doesn’t even have an engine tune however – that is a little something coming afterwards as Hennessey and crew dial in the setup. It’s earning 643 horsepower (479 kilowatts) and 570 pound-feet (773 Newton-meters) of torque at the wheels. Which is 177 hp (132 kW) and 119 lb-ft (162 Nm) far more than the stock C8 – and all devoid of an engine tune.
John claims the tuned Corvette retains the stock car’s snug drivability. In the video, he notes that you can quickly come to feel the added electric power, even nevertheless the C8 “is no slouch.” He believes 1,000 hp (745 kW) is feasible from the Corvette the moment the tune and setup are correctly dialed in, putting involving 820-850 hp (556-634 kW) to the ground. It’d be capable of sub-10-second quarter-mile moments in the a hundred and forty-mile-per-hour (225 kilometer-per-hour) range.

One particular point Hennessey and crew will have to look at as they ramp up electric power is the gearbox. John suggests they don’t know how the C8’s eight-speed gearbox will manage the added electric power. Which is a little something they’ll perform to fully grasp as they acquire the new twin-turbo setup. Cranking out 1,000 hp from the mid-engine Corvette appears otherworldly. But this is Hennessey we’re speaking about – and we can very likely count on even far more horsepower from the workforce as Chevy rolls out added higher-general performance Corvette types and trims.
