Aussie-built SS comes with a 6.2-liter V8 tuned to deliver 600 horses.
Having seen the Texan tuner’s Chevy SS hit 163 mph on a Texas toll road, it’s time for you to sit back and enjoy the 600-hp Hennessey-tuned SS complete the quarter mile in just 11.84 secs at 117 mph. The HPE600 package consists of a custom supercharger plus fuel system and ECU mods. Hennessey also offers an entry-level HPE475 package that boosts output to 475 hp via intake and exhaust mods, and a HPE1000 package, that adds a twin-turbo and 7.0-liter LSX V8 unit in order to generate 1,000 hp.
The upgrade packages also include Brembo brakes, a new suspension and alloys.
