Man Makes Homemade 48cc V8 Engine
Have you ever wondered what a mini V8 sounds like? Neither had we. But thanks to one man with an old mill and lathe who built one with a 0.48-liter capacity, we're happy to learn that a miniature V8 can still maintain a low-frequency, lopy idle.

Here's the little V8's impressive list of performance parts: 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 we have to agree with one of the video's commenters and request that the exhaust system be taken off for the next test run.
