It was a big weekend for Sean Kennedy, Mark Heidaker and the team at Hennessey. The trio managed to walk straight past the previous world record for the standing mile with a top speed of 257.7 mph. Kennedy took the wheel of Heidaker's Hennessey-prepped Ford GT for the feat. The vehicle used to be both twin-turbocharged and supercharged before Heidaker decided he needed a little more thrust. Hennessey then ditched the supercharger for a more efficient twin-turbo setup. The work seems to have paid off. Putting down that sort of speed in the span of a standing mile is nothing short of amazing, and the engineering behind the machine deserves all sorts of respect.

Of course, commanding the roided-out GT to do your bidding is also plenty impressive.

Tucked beneath that wild wrap is a white GT with a blue stripe, one of our favorite color combinations on this iconic shape. Hit the jump to see the run from inside the cockpit.

        You aren't kidding. I saw a Ford GTX1 the other day and had to pick my jaw up off of the sidewalk.

          They were not built by Ford it was built aftermarket by people that were on the original development team for the Ford GT. They never produced as many that were planned, they are ultra rare and total car conversions so expect these to be even more expensive than stock versions.

          I hear you about the GTX1. I saw a black one in Chicago last August and about **** my pants. Does anyone know how many GTX1s were built? I know it's a rare car, but I'm wondering how rare.

      A manual transmission, RWD, no launch control, and still made it to 257 in one mile? This car just told the Veyron to eat a ****.

      No side mirrors... Underground Racing always ran with side mirrors. And drag radials. Good speed, but should have been run in a street configuration.

        If it was done with the giant side mirrors, then they would have had trouble getting to the 257mph speed. I'm pretty sure they bolted them right back on after removing the wrap and returning the car back to the look.

      So what exactly did Hennessey do? If John Mihovitz did the engine, then what is left, bolting in a set of wheels and tires?

          Obviously you just don't know who John Mihovitz is, if all you can come back with is a meaningless quote from the article I just read. If Mihovitz had anything at all to do with the engine, Hennessey would have no part in it. Mihovitz is the greatest modular engine builder ever, and he's not going to put his name on something those jack monkeys at Hennessey have a part of. My guess is the engine and turbo kit were delivered, and Hennessey bolted it in, at most.

      I'm in the sign business. My biggest complaint is this new crop of wrap designers. Showing no restraint? If you look at it on the computer screen, it may look cool. If you stand really close and look at the detail it may look cool, but from 50 feet away, it looks like a bird **** on your car. Great drive, by the way. What ever happened to Heffner's 1100HP GT? I would think they would be all over a day like this.

        What little you know. I am the car owner and all parts were bought and paid for... Go throw your negative comments elsewhere. Kevin Kesterson out of the Hennessey Performance Shop did an amazing job so please go hate elsewhere... Thanks, Mark

          Congrats on your run Mark!! I struggled to get above 233 a few years ago, I don't think people understand how hard it is to break 250, never mind 260.... Again... Congrats to you Mark, and congrats to John. Just fantastic work all the way around. I hope to make a return trip next year, can't wait to see what you have for us then.

          Congrats on that amazing run, love the paint (vinyl?) scheme too. With 2000hp, it must have been a nightmare to hook up, but going by your new record, it sure worked well enough. I always admire the Ford GT, it's 7 years old and still able to dominate, especially with big fat turbos bolted on. Good work!

      There's been alot of talk about Hennessey being a shady outfit in the past. Whatever their business dealings, this is proof that they really can build a helluva car.

        Actually, the bigger surprise is you proving me right on how you only post on Hennessey articles just so you can insult Hennessey.

          I was playing nice, Elmo. Posted on other posts -- feel free to look around. Seriously, I was only recognizing that you changed your name -- all in the name of fun.

      I suppose this is the car record? I recall reading about turbo Hayabusa that did 286 mph?
