Put down 1K of Power with the HPE1000 Corvette Stingray!

HPE1000 Chevrolet Corvette

Because 1,000 is a nice, round number.

The seventh-generation Chevrolet Corvette Stingray made quite an impact when it was first unveiled. It made ‘America’s Sports Car’ a thing to be very proud of again. It’s not afraid to take it to the exotic competition from overseas – and beat it. Hennessey Performance is giving the sports car a bit of help with their new HPE1000 Supercharged Upgrade for the Stingray and Grand Sport model that pushes output past the 1,000-horsepower mark.

To get there, the 6.2-liter, naturally-aspirated LT1 engine was swapped out for a new Stroker engine with a 4.0-inch Stroker crankshaft. The new engine boasts a 10.0:1 compression ratio with forged aluminum pistons, Billet steel H-beam connecting rods, and ARP bolts. Everything has been balanced, blueprinted, and assembled by hand.

A new high-flow supercharger system complete with an extreme duty intercooler system to keep temperatures regulated was also installed as part of the HPE1000 Supercharged Upgrade for the Corvette. CNC-ported cylinder head ports, competition valves, flow testing, and milled chambers were also extensively worked on by the Hennessey Performance team amongst a laundry list of other goodies.

To get all those exhaust gasses out as quick as possible from the V-8, 1.75-inch stainless steel long-tube headers were installed and connect to a new mid-pipe, high-flow catalytic converters, and out of the centrally-mounted quad tailpipes.

After some serious dyno testing and a full HPE engine management upgrade, the HPE1000 Chevrolet Corvette produces 1,008 bhp at 6,500 RPM and 918 lb-ft. of torque at 4,000 RPM. This enables the super car to reach 60 mph in 2.5 seconds as tires struggle for grip. The quarter-mile disappears in just 9.7 seconds at 147 mph as well while the top speed is all the way back past 220 mph.

And while 1,008 bhp is a serious amount of power, the factory manual transmissions are more than up to the task of handling that power. The HPE1000 Supercharged upgrade also comes backed by a 1-year, 12,000-mile warranty. As part of the upgrade, Hennessey will add all their badging, serial-numbered plaques, and some custom floor mats to distinguish it when it’s not destroying its rear tires.
