Hennessey has offered a teaser of the performance that’s to come from its new tuning program for the 2014 Chevrolet SS. In its latest video, Hennessey shows one of its modified SS sedans, still in an initial state of tune, barreling down a stretch of Texas toll road--with full approval from the boys in blue (Hennessey regularly helps authorities test the road’s TxTag toll system).

Hennessey has applied its HPE600 Supercharger upgrade for the car but is keeping quiet on the details. Previous HPE600 upgrades for other cars offered around 600 horsepower, which would be quite the leap on the stock 415-horsepower rating of the 6.2-liter V-8 found in the SS if Hennessey maintains that level.

The top speed reached in the video above is 163 mph, though Hennessey states that this is limited by the SS’ gearing.

Some of Hennessey’s planned upgrades for the SS include high-flow air induction systems, engine management tuning upgrades, high-flow intercooler systems, exhaust system upgrades, turbo system upgrades, Brembo brake upgrades, suspension upgrades and wheel and tire packages.
