Check Out Hennessey’s 1,000 Horsepower Supercharged Corvette

HPE1000

Hennessey has taken the old C7 Corvette Grand Sport and created a 1,000 horsepower monster.

As we await the arrival of the next generation of Corvette, which is reported to have a mid-engine configuration with up to 1,000 horsepower, Hennessey has decided they’re tired of waiting. So they’re making their own 1,000 horsepower Corvette out of the old C7 model, and they’ve taken the Grand Sport trim as their starting point.

They call it the HPE1000 C7 Grand Sport, and it’s a little more extensive an upgrade than most of Hennessey’s projects. Rather than using the standard LT1 V8 engine and then giving it a bunch of upgrades to generate more power, Hennessey has tossed that engine away in favor of a 416 CID Stroker engine, which is basically a 6.8-L LS V8 crate engine.

Then they gave it a whole bunch of custom components, such as forged aluminum pistons, CNC ported cylinder heads, titanium retainers, and “extreme duty” pushrods. And then they supercharged it since the climb to 1,000 horsepower is going to need at least a little forced induction.

The final power numbers are 1,008 hp and 918 lb-ft of torque. That’s quite a bit more than the stock Grand Sport’s 460 hp and 465 lb-ft. Zero to sixty takes just 2.5 seconds on its way to a top speed of over 220 mph. Quarter-mile times are in the 9s, with Hennessey’s best recorded run of 9.7 seconds at 147 mph.

Hennessey doesn’t mention anything about upgrades to the transmission on their website, however, they do mention the 8-speed automatic is “upgraded from stock” in their video. The website also mentions that this is compatible with the 7-speed manual Grand Sport if you prefer a stick.

No upgrades to the brakes or suspension are shown, but at least the Grand Sport comes with magnetic dampers and big Brembo brakes. They’ll be working hard keeping 1,000 horses in check.

This upgrade only comes with a 1 year or 12,000-mile warranty, along with the usual assortment of Hennessey badges, serialized plaques, and floor mats. If you can’t wait for a C8, then Hennessey is likely your best bet for an extreme ‘Vette.
