The engine tune is still unknown.

The 2020 Chevy Corvette C8 production has begun – although it was already underway before everything stopped – and owners can now enjoy their new sports car. This means that aftermarket tuning shops can also get the latest Chevrolet. Hennessey one of these shops is one example. The team has tested the Corvette on the Dyno, created a prototype twin-turbo setup and then uploaded the videos. We can now watch John Hennessey take the wheel of the turbocharged Corvette to see how it handles its new power.

John’s driving impressions were all that was shown in the video. Any comparisons of performance numbers will be left for a later video. He mentions that there are some check engine lights, but the turbocharged Corvette does not yet have an engine tune. That will be done later by Hennessey’s crew. It produces 643 horsepower (479 Kilowatts) at the wheels and 570 poundfeet (773 Newton meters) of torque. It produces 177 horsepower (132 kW) as well as 119 lbft (162Nm) more than the stock C8. And all this without any engine tune.

John claims that the tuned Corvette maintains the stock car’s comfort driving dynamics. John notes that the Corvette’s tuned power can be felt immediately, even though it is powered by the C8. He estimates that the Corvette will produce between 820-885 hp (556-634kW) and 0-100 mph. It would be capable of sub-10 second quarter-mile times in the 140-mile per-hour (225 km/h) range.

Hennessey, crew and others will need to inspect the gearbox as they increase power. John states that they aren’t sure how the C8’s 8-speed gearbox will handle the extra power. They’ll be able to work out the details as they create the twin-turbo setup. It’s amazing to see the Corvette mid-engine produce 1,000 horsepower. This is Hennessey, and we can expect more horsepower as Chevy releases new high-performance Corvette models.
