WENDOVER, UTAH - Hajek Motorsports has broken two land speed records using both a diesel and biodiesel-powered 2011 Ford F-250 Super Duty at the famed Bonneville Salt Flats. Using a mostly stock truck with the new 6.7L Power Stroke V-8, the team achieved a speed of 171.123 mph on regular diesel and 182 mph on B-20 biodiesel.
The Ford truck broke the B Production Diesel Truck record of 166.850 mph by a Duramax diesel GMC. This class is normally comprised of race vehicles with extensive aftermarket modifications. The F-250 that Hajek Motorsports ran is something of a rarity as it used extensive production parts to perform at high speeds.
Underscoring that the 2011 Super Duty is the cleanest Power Stroke ever, a land speed record was also set using soy-based biodiesel fuel. The truck broke the biodiesel land speed record of 130.614 mph.
Every 6.7L Power Stroke turbo-diesel can operate on a mixture of diesel up to 20-percent biofuel. This capability is significant for the Hajek Motorsports team given its history and support for sustainable farm-based fuels and desire to prove that speed and performance are not compromised by using fuels like E-85 and B-20 biodiesel.
"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."
Hajek, a soybean and corn farmer from Oklahoma, knows a thing or two about Ford F-250s and biodiesel fuel. He owns six for use on his farm, with his 1997 Ford F-250 having accumulated more than 400,000 miles.
"Super Duty has always been the leader in the heavy-duty truck segment," said Brian Rathsburg, Ford Super Duty marketing manager. "Breaking these records reinforces our leadership position, allows us to raise awareness around the truck's biodiesel capabilities, and gives us an opportunity to reach out to enthusiasts in a fun and engaging way."
Ford engineers teamed up with Hajek Motorsports to design and install the modifications to the production-level truck. Changes were made only to the top-end components of the engine including the high-pressure fuel pump, fuel injectors and turbochargers for more fuel flow. The compression ratio was modified as well.
"The engineering that went into the base engine provided us with a rock-solid foundation to start from," said Paul Niessen, powertrain engineer. "And it worked out great since we increased the output of the engine by more than 50 percent over production with just a few changes."
Work on a chassis dynamometer before the attempt proved the engine was able to adapt to biodiesel fuel and deliver on both horsepower and fuel economy. It also verified the performance of the production transmission and drivetrain.
Components were added for safety purposes, including a full roll cage and five-point harness.
The 6.7L Power Stroke V-8 turbocharged diesel produces best-in-class 400 horsepower and 800 lb.-ft. of torque with best-in-class fuel economy, further strengthening Super Duty's best-in-class towing and payload capabilities. The Ford-engineered diesel engine uses inboard exhaust architecture, an automotive-industry first for a modern production diesel engine.
Key features of the new 6.7L Power Stroke V-8 turbocharged diesel engine:
- Compacted graphite iron engine block.
- Aluminum cylinder heads.
- Single-sequential turbocharger with double-sided compressor wheel mounted on a single shaft uniquely center-mounted on the engine block.
- Unique inboard exhaust and outboard intake architecture.
- High-pressure fuel system - new Bosch 29,000-psi common-rail fuel-injection system.
- Standard biodiesel compatibility up to B-20.
In 2009 Hajek Motorsports propelled an E-85-powered Mustang to a land speed record at Bonneville with a record-breaking run of 255.764 mph and an exit speed of 258.410 mph with Danny Thompson, son of motorsport icon Mickey Thompson, behind the wheel.
In 2010 Hajek Motorsports, Ford Racing, Wood Brothers, Bud Moore and NASCAR driver Bill Elliott teamed up to establish a closed-course speed record on E85 with the reconfigured Bonneville land speed Mustang at Talladega Super Speedway. On the second attempt Elliott ended the day with a crash, but not before establishing an E-85 record of more than 170 mph.
