How fast do you think Mustang GT can go? This is rather tricky question because for such car the sky is the limit really. When 435 horsepower from the stock 5.0-liter engine is not enough, the specialists from Hennessey Performance come to the rescue. With their HPE700 package, the Ford Mustang receives a power and performance upgrade which rockets the car like never before. There is one certain thing - John Hennessey and his gang of ultimate-performance creators are not scared to travel as fast as the light.

What would make the 435-ponies-car achieve even more dazzling results than before? The answer is simple: an additional 2.9-liter supercharger, refined fuel injectors and custom engine calibration.

In order to test the immense power of the tweaked beast, Hennessey team of technicians and experts rounded up and drove to Uvalde, Texas, to do some testing on the 8.0 mile high speed oval. After completing a warm up lap, Hennessey tried the performance of the Ford Mustang GT HPE700 at a higher speed. He comments; "Cruising through the final turn I was trying to maintain 120-130 mph while building some speed as I neared the straight. When I hit the straight, I wanted to be around 140 mph and then let all of the Mustang's horsepower run wide open. The car pulled very strong and just kept pulling. I hit a pretty nasty bump around 170 mph and kept my foot on the gas. Then I hit the rev limiter at just over 195 mph according to the Racelogic VBox display".

So, all in all, the spectacular 195 mph top speed and 717 HP are joined by 632 pound-feet of torque. Thanks to the upgrade, the 2015 Hennessey Ford Mustang GT covers the 60 mph run in just 3.6 seconds, and completes the quarter mile in 11.2 seconds at 130 mph.

As it looks like, everything seems to run faster in Texas, don't you think?
