A twin-turbo Ford GT tuned by Hennessey Performance has set the standing mile world record of 257.7 mph (414 km/h) at the Texas Mile high speed event in Beeville this past weekend.

Held at the Chase Field Industrial Complex, the Ford GT owned by Mark Heidaker and driven by Sean Kennedy was 4.6mph faster than the runner up. The record setting run was conducted during cool conditions early Sunday morning.

The weekend started on Friday with the first two runs clocking 216 mph and 228 mph. By the end of the day, the team had just cleared the 230 mph mark at 230.6 mph. On Saturday morning their first run produced a 246.8 mph speed and then followed up with a 250.1 mph speed which matched the previous record. However, instead of trying to break the record the same day, the team decided to wait until more favorable conditions Sunday morning. The decision obviously paid off.

"I was impressed with how hard it pulled in fourth and fifth gears on that run," explained Kennedy following his 257.7 mph record. "I think I can do better in the lower gears next time and we can run an even better speed."

The car is a modified Ford GT with twin Precision Turbochargers, breathing into a racing engineered 5.4 liter Accufab Racing engine, which burns 117 octane racing gasoline. The engine and power management as well as the data acquisition system are MoTeC and were calibrated by MoTeC tuner and racing consultant, Shane Tecklenburg (Tuned By Shane T) of Huntington Beach, California who was also on hand to assist the team during the event. Installation, engineering and fabrication duties were handled by Kevin Kesterson of Hennessey Performance Engineering out of Sealy, Texas who was also on hand as car chief for the team.

"I knew when I saw 204 mph come up on the scoreboard at the half mile, that it was on," said Kesterson. "I just couldn't wait to see what it was going to run out the back."

"We knew the car had it in it," noted Tecklenburg. "Our task was simply to find it and figure out a way to apply the power in the right places to take advantage of it. Using the GPS system with the MoTeC we are able to map out a power management scheme which allows us to extract the maximum acceleration from the car at any given point on the course. I consult with many teams in all levels of motorsport worldwide and these guys are as dedicated as any I have worked with. That shows in the preparation of the car and the results on track."

The team plans to attend the next event at the Texas Mile in October and hopes to break the record once again by hitting 260mph.
