Thanks to the 2015 Dodge Challenger SRT Hellcat there is a new magic number in the muscle car world – 707. To raise eyebrows these days in the power war, a vehicle needs to match or preferably exceed that palindromic figure.

The tuners over at Hennessey took a look at it for their 2015 HPE700 Mustang and decided to go one better. Well, ten actually, because they bestowed their latest creation with 717 horsepower and 632 pound-feet of torque.

The HPE 700 Mustang takes the standard Mustang GT with its 5.0-liter V8 and turns up the power a few hundred notches with a Roots-type supercharger running at 7.25 psi. Hennessey claims that this boosted 'Stang can rocket to 100 km per hour in about 3.6 seconds and cover the quarter-mile in 11.2 seconds at 210 km/h. For those keeping score at home, those figures are very similar to Challenger Hellcat.

To cope with all of the added boost, the engine gets a high-flow throttle body, upgraded injectors, new fuel pump, stainless steel exhaust and Hennessey's calibration for the engine management. Pricing for the package is $59,500, including the base 2015 Mustang GT, but the company is limiting production to 500 units for the 2015 model year. Founder John Hennessey told Autoblog that he has already received about a dozen orders for them.

However, Hennessey is also offering a host of upgrades to make the Mustang even more aggressive, like carbon fiber pieces for the front splitter, side sills, rear diffuser and spoiler. Further enhancements include 20-inch wheels with Michelin Pilot Super Sport 2 tires and 15.1-inch Brembo front rotors.

Hennessey also talked about the company's future upgrades for the Mustang's 2.3-liter EcoBoost. He said in the neighborhood of 375 horsepower is possible with some tweaks, and based on the company's other experiences with EcoBoost engines, they are "easily tunable."
