When it comes to speed of automobiles it is never enough for some people and to achieve more they bring in all their resources and come up with shocking speeds. John Hennessey is one of them. The 2015 Mustang GT is a right out of the box performer, and it figures in the 2015 10Best Cars list. For a great price, it offers a lot of goodness to the owners, but the 435 horses offered by the regular 5.0 Liter is not sufficient enough for people like John Hennessey.
For John Hennessey, it is surely is not enough, the boss of Hennessey Performance is not keen on any car that produces less than 700 hp of power. So he set on enhancing the Mustang by adding a 2.9 Liter supercharged engine, custom calibrated the engine, upgraded the fuel injectors and installed floor mats and headrests with embroidery to transform the vehicle into a screaming jet with 717 hp power and a 632 lb-ft of torque. The later simply buries your cranium into the headrests and does not snort or scream while doing that.
With the new HPE700 kit, the Mustang GT is good for a timing of 3.6 seconds against the 0-60mph according to Hennessey. At the speed of 131mph, the car makes the quarter miles in 11.2 seconds. The modifications he hopes will push the car to achieve the much-awaited 200mph speed mark. The mark though was not achieved but it still managed to scream to a GPS checked 195.2mph. The car was breathing through the factory exhaust when it was ripping to the speed. Hennessy tested his own personal Mustang with HPE700 at the Continental Tires Proving Grounds in Uvalde, Texas.
In Texas, everything seemed faster, and that also include Florida where Hennessey put the Venom GT on the NASA runway to achieve the unthinkable top speed of 270 mph.
