Would you drive a Ford F-250 Super Duty Crew Cab at 182 miles per hour, even at the Bonneville Salt Flats? My answer to that question, without much consideration, would be a resounding “no.” Ask Brent Hajek, a farmer from Oklahoma and owner of Hajek Motorsports, the same question and you’re likely to be met with an enthusiastic “hell yes!”
Hajek just set two land speed records in a slightly modified 2011 Ford F-250 Super Duty pickup equipped with the new 6.7-liter PowerStroke diesel engine. On pump diesel, the truck ran a top speed of 171.123 miles per hour. Running B20 biodiesel, the truck clocked a top speed of 182 miles per hour, besting the old biodiesel record by over 52 miles per hour.
You’d think that Hajek’s truck looks nothing like a stock F-250, but you’d be wrong. The truck is lowered and sports purpose-built tires on fully-covered wheels, but the drivetrain is remarkably close to stock. The truck has a higher flow high-pressure fuel pump, new fuel injectors, larger turbos and a higher compression ratio than stock, but none of the truck’s bottom-end components were altered for the record attempt.
Hajek Motorsports is no stranger to record speed run attempts. In 2009, the team ran an E85 fueled Ford Mustang to a record-breaking speed of 255.764 at Bonneville. In 2010, the team tried to set a closed-course speed record with the same Mustang at Talledega Super Speedway, but a crash took the car out of contention. Prior to the crash, the Mustang had set an E85 record of 170 mph.
