We’re not 100% sure of the “world’s smallest” claim, but the engine above sure is small. And it works just like its bigger sibling, internally combusting its fuel, albeit with a paltry 45cc displacement. Yes, 45cc. Despite the small size, there’s a good amount of tech in there.
Scratch built 45cc V8 with Megasquirt MS2 fuel injection.made in the shed with an old manual Bridgeport mill and a 95 year old lathe. Single fuel injector made from Punto injector internals. Pressurised oil system, drilled crank, alloy block, cast iron wet liners, vernier cam pulleys, Walbro fuel pump, tungsten alloy flywheel, bead blasted and anodised finish, throttle pos sensor on butterfly shaft, 24tooth trigger wheel for megasquirt.
Uh huh… we understand some of those words. And we fully understand that this is a one of a kind engine that might be up for purchase, direct from the man who made it. We’ll post links to his website where you might be able to reach him to inquire, if this really tickles your fancy.
