Man makes homemade 48cc V8 engine

A man with an old mill and lathe built a mini V8 with a 0.48-liter capacity. It can still maintain a low-frequency while idle. The V8 has an impressive list of performance parts including alloy block with cast-iron wet cylinder liners, pressurized oil system, drilled crankshaft, tungsten-alloy flywheel, Megasquirt MS2 fuel injection with 24-tooth trigger wheel, a single fuel injector, vernier cam pulleys, and a throttle-position sensor on the throttle butterfly. Gasoline is routed from a jar on the work bench. The mini V8 sits on a platform while the engine builder opens the throttle via a tiny wheel next to the air scoop. The sound it makes is nice and V8-like at idle, but perhaps the exhaust system should be taken off for the next test run.
