68 horsepower per liter! Air-cooled? You betcha. This hand-built V12 engine, the fruit of hobbyist Ralf Drendel's labor, clocks in at a mere 87 cc's of displacement and cranks out a
whopping mere 6 horsepower. That's three times the pistons of the worlds smallest 4 cylinder and probably three times the headaches. The little terror was designed with RC planes in mind, but it's so thirsty its creator is having second thoughts. You wouldn't believe how hard it is to find pictures of the beast, but the video, as you can see above, is utterly glorious. Hit the jump for a picture of the mighty mini wonder.
Even though your standard Briggs and Stratton single will make more go power than this little bugger, you'd be the envy of all the other cul de sac racers with this strapped to your go-kart. Go-Kart? Who am I kidding, screw junior, slap this on your string trimmer! [wawu.edu]
