What you’re looking at is an Evinrude 300xp, 2-stroke, V-8 engine on. This particular engine, however, has been modified by VM Performance in Vasteras, Sweden. Currently, the engine has eight carburetors and sounds like the wildest weed whacker or chainsaw engine ever made. There are few details about the engine, but according to the video description, the expansion chambers are homemade by the process of hydroforming. Other modifications included milling of the original exhaust and filling the block with plastic – essentially sealing off the cooling system. VM Performance apparently plans to remove the eight carburetors and replace them with electronic fuel injection. Sources say the engine will eventually be used in a Volkswagen Drag car.
