So you think you’ve seen it all, huh? Well we’re guilty of thinking that from time to time as well, but then along comes, of all things, a screw-blown Hemi that’s been converted over to run on diesel.
Yes, you read that right. As the story goes, diesel racing aficionado Curtis Halvorson of Extreme Engine Development in Calgary, Alberta, which includes among its successful projects the record-setting, 341 MPH diesel-powered Mormon Missile streamliner, has taken a combination similar to that found in a Top Alcohol Funny Car and converted it to run on diesel fuel in what is likely the wildest concoction the diesel drag racing world has ever seen.
The engine is based on a 511 cubic inch Brad Anderson Hemi with custom-built four-valve-per-cylinder cylinder heads by Extreme Engine Development, and sports a Bryant crankshaft, Bill Miller rods and pistons, and is topped by a PSI D-rotor screw supercharger, all fed by Bosch LBZ injectors with a standalone tuning and fuel system. Halvorson and company have the big monster mated to a B&J three-speed transmission with a U.S. Transmission Quick Drive torque converter unit inside the Brad Hadman-built pickup truck.
The EED team recently fired the truck up in their shop and took it to wide-open-throttle at some 4,000 RPM, which sent enough black smoke to darken a city pouring out from the zoomie headers. Dyno information isn’t available, but the team is said to be targeting 2,500 horsepower, which would help push the truck well into the sixes if they can achieve it.
Halvorson reportedly debuted the truck at the Texas Raceway in Kennedale on Friday, making some burnouts but running into a mechanical gremlins that kept them from making any representative runs. Rest assured, however, that we’ll be bringing you more on this incredible pickup in the coming weeks as more information — and hopefully on-track numbers — become available.
