The guys from the company Hennessey installed a turbocharger on the Chevrolet SS, as a result, the power of its power plant has increased quite significantly. The car was tested on the dyno.

It is a pity that in our country Chevrolet SS is not an American sports sedan with rear wheel drive powered by a powerful V8 engine. Known tuning studio Hennessey decided to add power to this car. A couple of minutes ago, a video appeared on their YouTube channel showing the measurements of the power of the upgraded Chevrolet SS in the dyno. Before we disclose the measurement results, let’s recall the standard SS specifications.

Sold in the United States from 2014 to 2017 model years, the Chevrolet SS sedan is built on an updated VF Holden Commodore chassis. The model was equipped with a 413-horsepower LS3 V8 engine rated at 415 horsepower, connected to a 6-speed automatic or 6-speed manual gearbox. Torque transmitted only to the rear wheels. In fact, sales of this car were rather low.

A Hennessey turbocharger was installed on the Chevrolet SS, which was sent to the dyno for power measurement.

Before the power measurements, the Hennessey tuning engineers took into account a 15% power loss, so the results were expected to be just over 350 horsepower (520 Nm) to the rear wheels. In actual tests, the sports sedan was able to generate 373 horsepower.

In the end, what power did the Hennessey supercharger add to the American sedan? The dynamometer graph shows an incredible 584 horsepower and 698 Nm of torque – an increase of more than two hundred horsepower for the rear wheels, as well as a decent amount of torque, compared to the standard Chevrolet SS.
