Hennessey Offers 1,000 Horsepower Upgrade for Chevrolet SS

The American tuner Hennessey has released details on its performance upgrades for the Chevrolet SS performance sedan, with the most powerful option offering 1,000 hp.

A stock 2014 SS outputs 415 horsepower and 415 lb-ft of torque. Hennessey offers various packages to improve the performance, starting with the HPE475. This liberates 457 hp from the SS's 6.2-liter LS3 V-8 with the use of new intakes, headers, high-flow catalytic converter and an ECU modification.

Mid-range packages, each with its own price and level of performance, are labeled HPE550, HPE600, HPE650 and HPE800.

The top-of-the-line HPE1000 package is the most extreme of all. It involves swapping the engine for a twin-turbocharged 7.0-liter LSX V-8 that has been equipped with a new intake manifold, low compression pistons and a Callies 4340 forged steel crank. The engine also has a custom camshaft, upgraded fuel injectors and a stainless steel exhaust system. Other notable highlights include an air-to-air intercooler, a high-flow air filter and a new ECU. The SS's six-speed auto with paddle shifters can also be mated with this engine, though it will require a performance build and torque converter upgrade. With all these changes, the Chevrolet SS outputs 1,000 hp.
