Just how fast will a 2011 Ford F-250 go, with basically stock parts? That's the answer that Hajek Motorsports and Ford Engineers set out to discover with their 6.7-liter turbodiesel V-8 F-250. On the way to discovering that answer (and a 182 mph top speed), the team managed to break three production diesel truck records at the Bonneville Salt Flats.

The three speed records that this lightly-modified F-250 broke were in the B Production Diesel Truck class, at the Bonneville Salt Flats. The truck broke the biodiesel record, using soy-based fuel by hitting 130.614 mph. The F-250's second fastest record of the day was using regular diesel fuel, where it managed to hit 171.123 mph. The third and final record of the day was using B20 biodiesel, where the F-250 topped out at 182 mph. For comparison's sake, the old record was set by a Duramax-equipped GMC Sierra HD, which only managed 166.850 mph.

The most remarkable thing about the F-250's speed is that it the truck remains mostly stock. Ford says that its engineers and Oklahoma-based Hajek Motorsports only installed a high pressure fuel pump, new fuel injectors, new turbos, and modified the compression ratio. Aside from the performance modifications, the F-250 was also fitted with a roll cage, five-point harness, a drag chute, aerodynamic fairings for the front bumper, and the obligatory salt flat moon-dish wheels. The F-250's drivetrain and transmission were stock.
