Even though it’s the Dodge Challenger Hellcat that probably made more headlines toward the end of last year, there is no denying that 2014 was the year of the new Ford Mustang. Sporting a multi-link rear suspension for the first time and an all-new design that blends retro and modern motifs, the now globally sold Mustang is still a true American icon. Which is probably why Texas-based tuner Hennessey wanted to thoroughly modify it.

Using the 5.0-liter Coyote V-8 as a base, John Hennessey’s team of engineers shoehorned a 2.9-liter supercharger on top of the mill and modified the engine management system. That doesn’t sound like much, but the results speak for themselves when it comes to the added performance. Known as the HPE700 package and available as a limited edition for just 500 units from the 2015 model year, the mods give the new Mustang a 0-60 mph time of 3.6 seconds, and a quarter-mile time of 11.2 seconds at 131 mph.

Still not impressed? John Hennessey recently took his personal HPE700 for a top-speed run at the Continental Tires Proving Grounds in Uvalde, Texas, where the car managed to hit 195 mph on the straight before the rev-limiter intervened. According to Hennessey, this was just a trial run, and after further modifications they will return to try for 200 mph.

Developing at least 717 horsepower and 632 pound-feet of torque at the crank, you would have probably expected the Mustang HPE700 to go well above 200 mph on its top speed run, especially since the Challenger and Charger Hellcat can apparently do it with a bit less horsepower.

From what I gathered watching the video, it seems likely that the stock transmission ratios were what kept the car from going any faster, so after a bit of tinkering in the Hennessey shop the car should be faster. Either way, the fact that apart from the giant supercharger and a new ECU the car was pretty much stock is pretty commendable, especially since 195 mph is faster than Ford engineers intended the Mustang to go on stock suspension and aerodynamics.
