Dynoed: Hennessey’s Twin-Turbo HPE800 Chevrolet Camaro Rated at 847 HP

A stock 2010 Chevrolet Camaro SS already has 426 horsepower on tap from its 6.2-liter V-8, but for those who want [grunt] more power, Hennessey Performance has the solution: the HPE800 Camaro. The Texas-based tuner recently strapped its twin-turbocharged muscle car to the dyno and recorded some astonishing figures.

Along with the aforementioned pair of turbochargers, The HPE800 upgrade package also treats the 6.2-liter V-8 to a complete set of balanced, forged innards, customized camshafts, a high-flow oil pump, ported heads, a larger throttle body, ported intake manifold, upgraded fuel system and injectors, and a less restrictive exhaust system. The kit can be applied to cars with either the six-speed manual or the six-speed automatic transmission, but Hennessey treats both gearboxes so they’ll withstand some extra power.

That’s a good thing, because the HPE800 Camaro has plenty of power. After watching video of the car strapped onto a chassis dyno, the entire package allows GM’s muscle machine to lay down an incredible 740 horsepower and 707 pound-feet of torque -- at the rear wheels.

But wait, there’s more. Those figures are achieved when running 11 pounds of boost, but if you tweak the standard boost controller to 16 psi, those figures jump to an Earth-twisting 847 horsepower and 801 pound-feet of torque.

Hennessey Performance Engineering will install the kit at its facilities just outside of Houston, Texas, and back it with a one-year/12,000-mile limited warranty. Hennessey hasn’t released final pricing for the car just yet, but it’s likely in the $100,000+ neighborhood, much like its LS9-powered HPE700 Camaro.
