The art of racing a truck is not for the faint of heart. After all, trucks are about as aerodynamic as a brick, extremely heavy, and even when equipped with huge engines, far from fast. But there are exceptions, like the Hajek Motorsports F-250, which just smashed the land speed records for diesel and biodiesel trucks.
The F-250 Super Duty is a rugged truck, without a doubt, but far from the ideal land-speed racer. But that didn’t stop Team Hajek from going over171 mph, running the F-250 on straight diesel. When they filled the tank with B20 biodiesel, the truck went even faster, going at speeds over182 mphon theBonneville Salt Flats. Depending on the feedstock, biodiesel can have an even greater energy density than diesel, which explains the extra10 mphthe Hajek F-250 gained on B20.
Perhaps most impressive though is that the F-250 was left largely intact. While the fuel injectors, fuel system, and turbocharger were all upgraded, the 6.7 literPower Stroke V8 was otherwise mostly stock. A testament to how far automobiles have come…and the power potential locked in green fuels. And with trucks set to get leaner, meaner, and a whole lot greener, racing a pickup may start to get a lot more practical.
Hajek Motorsports blew away the previous biodiesel truck land speed record, which sat at 130 mph, and they’ve got themselves a nice little cushion to sit on for now. But the thing about land speed racing is that there is always somebody out there looking to break your record, so they best not get too comfortable. And with the 200mph mark so close, maybe a few more tweaks can get them over that next big hurdle.
