Canadian Engine Builder Builds Hemi Drag Diesel

Wild Engine Makes Plenty of Power, Smoke

Oct 6, 2014
At least in the context of the truck world, the terms “Hemi” and “diesel” are descriptions of two very different engine platforms and architectures. The Hemi has been part of gasoline engine performance history since the 1950s and reached its zenith of popularity in the 1960s. It became the basis of Top Fuel dragster engines. So you’d think the venerable classic Hemi might have reached its logical conclusion of performance development. Evidently, Curtis Halvorson at Extreme Engine Development of Calgary, Alberta, didn’t get that memo. In a move sure to upset both the Hemi and diesel purists, Halvorson created a diesel Hemi race engine.
As the Hot Rod blog post details, the engine’s block is pretty much a standard-issue Top Fuel-spec aluminum block. For conversion to oil-burning duty, a set of custom heads were crafted by Halvorson that hold Bosch common-rail injectors where the spark plug would normally reside. Halvorson is targeting 2,500 hp for the supercharged engine.
You can watch the engine running in the video below. The sound is hard to describe other than being very loud. The engine also produces surprisingly little smoke under light load, until the dyno operators go wide-open-throttle on it, when it belches out copious amounts of black smoke in the last few seconds of the video.
