Listen to a miniature toy V8 rev up like the real thing

YouTuber JohnnyQ90 came up with a functional design for a toy-sized eight-cylinder engine that sounds like a no-nonsense muscle car motor when it revs up.

Initially, the unit suffered from all kinds of minor technical issues that prevented it from running smoothly, but the talented mechanic overcame them all. He equipped it with a special exhaust system and metal manifolds printed on a 3D printer. Despite being only 78cc (0.078 liters) large, the block can hit 9,000 RPM and output 5 horsepower (3.7 kW) to the wheels.

At a certain time point in the video, the drivetrain experiences a water pump failure, but the host says it did not cause any major damage.

The engine is available to buy for a cool $2,900, and you will be better off setting aside another @224 for that exhaust system.
