Shortly after Chevrolet->ke199 launched the SS sports sedan onto the market Hennessey Performance came up with a pretty amazing tuning kit that raised the standard output up to 600 horsepower -- up from 415 horsepower.

A few weeks ago, we got a look at the Hennessey SS hitting a top speed of 163 mph on a Texas Toll Road, and today the tuner released a video of the sports sedan running the quarter mile in 11.84 seconds at 117 mph. To put that into perspective, a Ferrari 458 Italia->ke3479 runs the quarter in about 11.5 ticks at 125 mph -- not too bad for a sedan.

The only update the model received besides that bad-ass HPE600 kit was a set of drag radials for extra grip.

As a reminder the HPE600 package includes a TVS2300 supercharger, HPE air induction system, fuel system upgrades and ECU modifications. A series of aesthetic updates were also made, including a carbon aero body kit and a carbon-fiber kit for the interior.
