2010 GT Belts Out 669 Coyote-Hunting Horsepower

Pretty much everyone in the domestic car world is familiar with the name Livernois Motorsports and Engineering in one way or another. The company provides engineering service, tuning, product development, and vehicle design for both the OEMs and the aftermarket, which gives Livernois the wherewithal to rev up a Three-Valve Mustang with Coyote-hunting power.

This 2010 Mustang GT is equipped with the company’s S775 package. With two custom tunes available — one with 93 octane and the other for E85 — this package is a great fit for those looking to ramp up their Three-Valve 4.6s.

The products in this package are developed within the company’s 36,000-square-foot facility with 15 vehicle hoists to provide installations. Also inside the facility is an engine dynamometer, a full machine shop, an engine-build facility, a cylinder head development center, flow benches, CNC machines, a fabrication shop, and more.

At this facility, Livernois, designs, installs, and tests it products as it did on Jeff’s Mustang in the video above.

It makes a couple of impressive runs with the 93-octane tune putting down 614 horsepower and 581 lb-ft of torque at the wheels, and the E85 tune pushing the numbers to 669 horsepower and 628 lb-ft of torque.
