While customer deliveries of the 2020 Chevrolet Corvette Stingray have yet to even begin, Texas tuner Hennessey Performance has already detailed a multitude of performance upgrades for the mid-engined sports car.

While recently speaking with Hagerty, Hennessey said that despite the difficulty in tuning the new E99 ECU featured in the C8 Corvette, it will do that as opposed to swapping in a new ECU and starting things from there.

According to a representative from the company, it remains unclear when tuners will be able to crack into the car’s ECU and start working their magic. “In the meantime, we expect to receive our first C8 in March or April and we will be busy mocking up our first supercharger and twin-turbo systems while we await tuning software,” the spokesperson said.

Early analysis from Hennessey suggests that the new 6.2-liter LT2 V8 engine of the C8 is very similar to the outgoing LT1 with the exception of a dry-sump oiling system and the tubular exhaust manifolds. Consequently, the company doesn’t envision running into any issues when drastically increasing power from the car.

Hennessey’s range-topping C8 Corvette package will pump out no less than 1200 hp. That figure will be achieved with twin-turbochargers and the stock fuel system but the tuner will have it running on E85 ethanol to ensure power is easy to find.

Another key area of the Corvette that will be modified is its Tremec dual-clutch eight-speed transmission. Hennessey has yet to work on this gearbox but says it will work with a vender well versed in upgrading transmissions for the Nissan GT-R, Audi R8, and Lamborghini Huracan.

“Most likely we will have to upgrade clutches and maybe other DCT internal parts,” a Hennessey representative said. “Depends on how the customer is going to drive the car. On the street with street tires is less strenuous, but for customers who want to run down a sticky drag strip with sticky tires—that may require more upgrade work in the transmission.”
