Hennessey Super-Supercharging 2015 Chevrolet Corvette Z06 to 1,000 HP

Chevrolet may have made a massive step up the horsepower ladder with the 2015 Corvette Z06, as the switch to supercharging has brought 650 hp, but this doesn't mean that the aftermarket developers have less work to do. Let's take Hennessey, for instance: the Z06 'Vette may be a few months away from its market arrival, but the Texan developer has already announced its program for the car and it's looking 1,000 hp good.

Hennessey's complete menu for the 2015 Corvette Z06 has something for all types of power thirst types, including three levels of power. Before we move on to describing these, we'll remind you the standard 6.2-liter LT4 supercharged V8 at the front of the car delivers a nicely rounded output of 650 hp and 650 lb-ft (880 Nm) of torque.

The muscle flexing

Stage 1 sees the output jumping to 750 hp at 6,300 rpm, with the main upgrades targeting the pulley, intercooler and cylinder heads.

Stage 2 takes this to 850 hp at 6,500 rpm and implies a 2.9-liter supercharger that replaces the stock 1.7-liter Eaton blower. As you can imagine, there are plenty of supporting mods here. The package even includes a custom hood, which can fit the reworked mechanical goodies.

As for the 1,000 hp Stage 3, this uses the 2.9-liter supercharger, but turns to forged internals, for instance. Speaking of which, you can check out the complete list of tech goodies for each package in the press release section below.

On top of all that tech work, you can have optional extras such as H10 monoblock wheels, carbon fiber door entry sills, as well as branded floo rmats and exterior badging.

The performance and warranty

In case you're wondering what happens with the warranty, you should know Stage 1 comes with a 3 year/12,000-mile coverage, while the other two are offered with a warranty of 1 year or 12,000 miles.

Hennessey hasn't published the performance figures yet, but we'll see the upgraded creatures hit drag strips across the US next year. Untill then, we want to remind you the stock car already plays the 0 to 60 mph (96 km/h) game in a brief 2.95s, when fitted with the optional 8-speed auto, while in 7-speed manual guise it requires 3.2 seconds for the job. We'll talk more about this on the drag strip.
