Hennessey Offers 1,000 Horsepower Upgrade for Chevrolet SS

Published: Thu May 01, 2014 by Marko P.  |  Source: Hennessey via MotorAuthority.com

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.
