1200 HP Chevrolet Corvette ZR1 Starter Upgrade with a Monster Dyno Run



We have already seen the 2019 Chevrolet Corvette ZR1, which performs its draw competition, both on the dragline and on the street. Given these adventures, one can wonder why we have included a dynamo run of the Chevy halo car – how can this still be interesting?

Well, you should know this is not a random dyno run coming from an owner who wanted to figure out how the new LT5 engine behaves in the real world.

Instead, the adventure we have here comes from Hennessey Performance, with the developer who has started working with the C7 Corvette ZR1. And as always, the process ended with a baseline dyno race, hence the piece of recording at the bottom of the page.

The Texan developer has already announced his program for the GM supercar, with the company set to offer three packages. These will see the output of the supercharged 6.2-liter V8 jump from the factory output of 755 hp to 850, 1000 or 1200 hp.

That's right, the Lone Star State firm aims to take the uber Corvette deep into four-figure territory. And you might want to know more about bits and pieces that will help you get there, so we focus on the 1200 hp update, whose maximum torque will be on a too boring 1.066 lb-ft. [19659004] It all starts with a displacement boost, as the V8 is set to jump to 7 liters. This will be merged by a bigger blower, with the list of support models being equally impressive. We refer to aluminum stamps, forged steel coupling rods, wiper shaft, gated cylinder heads, updated rollers, springs, holders, lifters and pushrods, along with a high floor air to air cooler and a custom exhaust system. The latter involves longitudinal pipe heads, midpipes and high-flow catalytic converters.

We keep an eye on these updates and return as soon as we get our keyboards on fresh materials.
