Ford F-250 Super Duty Sets Two Land Speed Records


It's not the kind of hauling that comes to mind when you think of pickup trucks, but a Ford F-250 Super Duty has set two land speed records for diesel and biodiesel trucks, Ford says.

At the famous Bonneville Salt Flats in Utah, Hajek Motorsports pushed a modified three-quarter-ton F-250 to a top speed of 171.23 mph, breaking the B production diesel truck record of 166.850 mph that was set by a GMC Duramax. Running on B20 biodiesel, the Super Duty set the unlimited biodiesel land speed record of 182 mph, breaking the previous record of 130.614 mph.

"Racing is part of Ford Motor Company's DNA, so it’s only natural for us to build a race vehicle that demonstrates Ford's leadership in the diesel and biodiesel truck market," said Brent Hajek, Hajek Motorsports owner. "The F-250 is an excellent truck with amazing capabilities. I'm amazed at how, with very few changes from stock, we were able to accomplish this."

Ford engineers worked with Hajek Motorsports to install the few modifications to the F-250's 6.7-liter Power Stroke V-8. To improve fuel flow, changes were made to the high-pressure fuel pump, fuel injectors and turbochargers. The compression ratio was increased, too, along with a new rear differential, according to Henry Platts, Ford SVT spokesman.

All the changes boosted the engine’s output by 50 percent over production, said Paul Niessen, Ford's powertrain engineer.

A stock 6.7-liter Power Stroke V-8 makes 400 horsepower and 800 pounds-feet of torque. In our recent Heavy-Duty , the 6.7 Power Stroke (inside an unloaded F-350 dually) ran the quarter-mile in 17.06 seconds at 83.03 mph.

We also dyno-tested the engine last year. See the results here.
