With 415 horsepower and 415 pound-feet of torque at its disposal, the Chevrolet SS is one of the most attractive rear-wheel-drive sedans you can buy nowadays. But if those figures aren’t enough to satisfy your thirst for power, the SS can be upgraded with help from tuning specialists such as Callaway] or Hennessey].

An update from the former will enable the SS to deliver 570 horsepower via an Eaton TVS supercharger and other enhancements. This is a huge improvements over the standard model, but don’t think the SS can’t handle more oomph. Because it can, and Hennessey’s new upgrade is out to prove just that.

Just like it did with the Camaro ZL1, the Texas-based company took things up a notch and replaced the 6.2-liter V-8 with a larger, 7.0-liter unit and a couple of ball-bearing turbochargers. Yes, we’re talking about the famous HPE1000 package that also comes with forged, low-compression pistons and connecting rods, a custom camshaft and stainless-steel piping and exhaust, just to name a few vital components.

The bundle enables the SS to deliver no less than 1,000 horsepower at 6,300 rpm and benefits from a professional installation, dyno tuning, extensive road testing and a one year or 12,000-mile warranty.
