See Turbocharged Chevy Corvette C8 Make 736 Wheel HP On The Dyno

The frenzy of the Corvette C8 does not seem to slow much. In this case, it literally accelerates considerably. A 2020 Corvette with the Z51 group of 495 horsepower can already reach 60 mph in three seconds. Bets on what a 736-horsepower C8 can do?

Unfortunately, this video does not include an acceleration breath, but it Is have a very powerful ‘Vette. The clip is from Extreme Turbo Systems, a company based in southern Washington, not far from Portland. They tinkered with Chevy’s supposedly un tunable C8, and as the company name suggests, turbochargers are an integral part of the equation.

If we are honest, the video is not terribly dramatic. The Corvette fires a chassis dynamo three times, looking very healthy but not too angry in any way. Dynojet reading tells a different story, as the first race shows the car producing 728 hp to the wheels. This equates to approximately 830 hp at the crankshaft, which represents a transmission loss of 12%. But wait, there is more.

The second run drops slightly to 726 hp, but the third run brings down the salary. The Dynojet records 736 hp and 669 lb-ft of torque at the wheels, with the boosted engine operating at 7.5 psi. If this number seems a little low, you are not alone. We can’t help but wonder how much power the LT2 is capable of with a little more boost.

The video claims that this is the first Corvette C8 set to exceed 700 hp on the wheels. It is practically impossible to verify such claims, as there are millions of tuning shops in the United States and not all of them are published on social networks. We can say that it is more than what we saw from Hennessey, which distributed a 643 hp not at all diminutive with a prototype configuration with double turbo.

According to Hennessey, this level of power has been reached without Programming changes to the car’s ECU, which can certainly be a scary proposition in terms of balancing air-fuel ratios. Extreme Turbo Systems says his car uses an “exclusive tuning solution and methanol kit”. There is no list for the turbo kit on the company’s website, so this seems to be a work in progress.
