What's the best way to get the tires off the rims quickly? Not by running the thing at 200 miles per hour on the dyno and having them explode, we're quite sure. That's what happened to a twin-turbo F-body Chevrolet Camaro with 1,800 horsepower at the wheels as it was being prepped for the Texas Mile, when the drag radials decided they would rather die.

Somewhere behind Hennessey setting a new top speed record at this year's Texas Mile with its camouflage Ford GT, a stock-looking 1996 Saab 900T pulled up to the line to see what it could do. The dealer showroom wheels wouldn't offer any indication that the 2.0-liter four-cylinder under the hood was getting help from a Garrett turbocharger, a tuned ECU and E85 gas to put out 465 horsepower at the front wheels.

We said they'd probably be out with an official video, we did not lie. The Hennessey-powered camouflage Ford GT sat at one end of the runway at the Texas Mile sitting still. At the other end of the runway it had broken its own speed record, the twin-turbo 5.7-liter V8 pushing the aerodynamic supercar up to 267.6 miles per hour, a 4.3-mph improvement over the old mark.

The record-setting Hennessey-powered camouflage Ford GT we showed you at this time last year headed back to the Texas Mile and managed to bring home yet another record. As you may recollect, last year saw Mark Heidraker's machine sprint to a record 257.7 mph thanks to propulsion from its twin-turbo 5.7-liter V8. The big mill sucks down race gas, and this year the creation pulled off a 267.6-mph run over the weekend. That feat set a new record for the event. Something tells us neither Heidraker n

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

John Hennessey recently returned to the Texas Mile with his 700-horsepower Cadillac CTS-V Sport Wagon for another shot at high-speed glory. The long-roof rocket managed to clip off a top speed of 189.7 miles per hour in the standing mile, which beat out last year's figure by a safe margin.
