Hennessey Performance Announces Loco 575 HP Shelby GT350 Upgrade

The 2016 Ford Shelby GT350 Mustang has only recently started making its way into the hands of customers, making 526 horsepower, supreme revability, and general road course prowess available to a lucky few.

Yet already, Hennessey Performance Engineering has created a power-boosting performance upgrade package, pushing the normally-aspirated 5.2-liter Voodoo engine’s output ever higher.

The new HPE575 Shelby GT350 produces an estimated 575 horsepower and 511 lb-ft of torque. That’s 49 horsepower and 82 lb-ft more than stock, without resorting to forced induction. Instead, power gains are made through a revised long-tube intake manifold, a few upgraded exhaust components, and Hennessey engine management. The low number of required parts makes the HPE575 upgrade a relative bargain, at $6,950 plus vehicle shipping with installation, and a 3-year, 36,000-mile warranty.

Of course, one can purchase and install the parts yourself for just $4,995, but s/he would lose out on the Hennessey Performance warranty, 100 miles of on-road testing, and dyno testing with a nifty little chart showing their individual car’s measured output before and after installation. Naturally, the HPE575 Shelby GT350 ships with a Hennessey exterior badge and floor mats, along with unique plaques in the cabin and engine bay with your car’s serial number.

Only 100 examples of the HPE575 Shelby GT350 will be built for the 2016 model year.
