Hajek Motorsports have broken two land speed records at the famed Bonneville Salt Flats using a near-stock 2011 Ford F-250 Super Duty.
Running on soy-based B20 biodiesel, the F-250’s new 6.7 litre Power Stroke V8 propelled it to 292.9 km/h – smashing the previous record for a B Production Diesel Truck of 210.2 km/h. On regular diesel the F-250 also became the new record holder with a top of 275 km/h, beating a Duramax GMC’s previous speed of 268.5 km/h.
Oklahoman soybean and corn farmer, Brent Hajek, said of his achievement:
“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. 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.”
The only modifications made were to the high-pressure fuel pump, fuel injectors and turbochargers so that fuel flow increased. The compression ratio was also altered and as a result engine output improved by more than 50 percent over the production units 298 kW and 1,085 Nm.
