Hajek Motorsports’ 2011 Ford F-250 Super Duty breaks two land speed records at Bonneville

Article by Christian Andrei, on August 28, 2011

Two land speed records were broken by Hajek Motorsports’ 2011 Ford F-250 Super Duty at the Bonneville Salt Flats with the use of both diesel and biodiesel-powered models. While the Ford F-Series is famous for its unrivaled capability and power, it has now entered the history books. The team was able to achieve a speed of 171.123 mph on regular diesel and 182 mph on B20 biodiesel. These used a mostly stock truck with the new 6.7-liter Power Stroke V8.

Ford’s Duramax diesel GMC broke the record of 166.850 mph, achieved by the B Production Diesel Truck. Typically, this class is composed of racers with some extensive aftermarket modifications. The F-250 that Hajek Motorsports is quite unusual because it features extensive production parts to perform at high speeds.

Ford claims that the 2011 Super Duty is the cleanest Power Stroke so far. Ford said soy-based biodiesel fuel was used. This truck was able to reach the 130.614 mph target.

Each 6.7-liter Power Stroke turbo-diesel can be used with a mixture of diesel up to 20% biofuel. The Hajek Motorsports team considers this as a significant achievement, considering its history and support for sustainable farm-based fuels.

Hajek Motorsports also wants to prove that speed and performance are not pulled down by the use of fuels like E85 and B20 biodiesel. Brent Hajek, the owner of Hajek Motorsports, said that it’s natural for them to create a race model that shows off its leadership in the diesel and biodiesel truck market.

Owner of Hajek Motorsports Brent Hajek quipped that since racing is part of Ford’s DNA, it was only natural for them to create a race vehicle that showcases the carmaker’s leadership in the diesel and biodiesel truck market. He added that while the F-250 is already an excellent truck with remarkable capabilities, only a few tweaks would make it more impressive. Hajek has six Ford F-250s in his farm, with the 1997 version already clocking over 400,000 miles.

Brian Rathsburg, Ford Super Duty marketing manager, remarked that breaking those records further augments Super Duty’s leadership position in the heavy-duty truck segment as well as allows Ford to heighten awareness of its biodiesel capabilities, and provides the carmaker a chance to reach out to enthusiasts in a fun and engaging manner. Engineers at the US carmaker and Hajek Motorsports closely collaborated to design and install the modifications to a stock version of the Ford F-250.

These tweaks include the installation of new high-pressure fuel pump, fuel injectors and turbochargers on the engine. Ford and Hajek also tweaked the truck’s compression ratio. Powertrain engineer Paul Niessen remarked that the engineering work on the base engine provided the team with a rock-solid foundation to commence the project from, allowing them to hike its output by over 50 percent with just a few modifications. Thanks to work on a chassis dynamometer, the team was able to prove that the engine could adapt to biodiesel fuel while delivering more horsepower and better fuel economy.

The same work also verified the performance of the production transmission and of the drivetrain. In addition, the team fitted new components – like a full roll cage and five-point harness -- to make the modified Ford F-250 safer.

Overall, the tweaks made on the 6.7-liter Power Stroke V8 turbocharged diesel engine could provide up to 400 hp of output and up to 800 lb.-ft. of torque while improving its fuel economy – thereby allowing the Super Duty to further boost its towing and payload capabilities. Moreover, this engine employs inboard exhaust architecture, the first time this was adopted for a modern production diesel engine.

This new 6.7-liter Power Stroke V8 turbocharged diesel engine comes with a number of key features like compacted graphite iron engine block as well as aluminum cylinder heads. Aside from its new and distinct inboard exhaust and outboard intake architecture, the engine features a single-sequential turbocharger with double-sided compressor wheel mounted on a single shaft that is mounted on the center of the engine block.

The new engine also boasts of a high-pressure fuel system in the guise of a new Bosch 29,000-psi common-rail fuel-injection system. Also, the engine has a standard biodiesel compatibility of up to B20 with E85 performance. In 2009, Hajek Motorsports managed to secure a land speed record at Bonneville with an E85-powered Ford Mustang. Piloted by Danny Thompson, this E85-powered Ford Mustang posted a run of 255.764 mph and an exit speed of 258.410 mph.

Heavy Hauling and High-Speed Racing: Hajek Motorsports Breaks Two Land Speed Records with Ford F-250 Super Duty

Hajek Motorsports has broken two land speed records for diesel and biodiesel trucks with a Ford F-250 Super Duty. Using the new 6.7-liter Power Stroke® V8 turbo-diesel, the truck hit a top speed of 171.123 mph setting the new B Production Diesel Truck land speed record. Running on B20 biodiesel the truck smashed the existing 130.614 mph unlimited biodiesel land speed record by running 182 mph.

The 2011 Ford F-250 is mostly stock, with changes to the high-pressure fuel pump, fuel injectors and turbochargers for more fuel flow. The compression ratio was also modified

WENDOVER, Utah, Aug. 19, 2011 – Ford F-Series is known for its unparalleled capability and power, but now it's found a place in the history books: 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 6.7-liter Power Stroke® V8, the team achieved a speed of 171.123 mph on regular diesel and 182 mph on B20 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 6.7-liter 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 E85 and B20 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.
