While the aftermarket races to churn out the first performance upgrades for the new 2020 Chevrolet Corvette C8, the C7 generation is still flush with options. For example, Texas-based tuner Hennessey Performance Engineering offers several packages for the C7-generation Corvette Z06, including the HPE850 Upgrade, as featured in the following video.
Right out of the box, the C7 Chevrolet Corvette Z06 is impressive, doling out 650 horsepower and 650 pound-feet of torque thanks to the supercharged 6.2L V8 LT4 engine. However, Hennessey isn’t the sort of outfit that’s satisfied with anything “out of the box,” so it developed the HPE850 kit to boost output up to 850 horsepower and 715 pound-feet of torque.
Making it all possible is a long list of parts and upgrades, highlighted by a new pulley, high-flow cylinder heads, new long-tube headers, upgraded valve springs, a high-flow intake, and a custom camshaft. Put it all together and apply it to the rear wheels, and the end result is a Corvette Z06 that will sprint to 60 mph in 2.6 seconds and fly down the quarter mile in 10.3 seconds at 136 mph. Impressive stuff.
Granted, it’s one thing to see all those specs and numbers on a piece of paper, and quite another to see it in the real world. As such, Hennessey Performance is showcasing what a HPE850 Corvette Z06 can do in this one-minute, 48-second video.
The video is simple, showing the go-faster Vette as it blasts around Hennessey’s test track. We get to see it rolling and stationary, while also getting an earful of the exhaust note. At full blast, that LT4 sounds rather tasty indeed.
