Miniature Porsche Engine Emits Impressive Sound

This miniature engine is exactly one third of the size of a Porsche 911 engine. It was built by a Dutch precision instrument maker more than 40 years ago and is completely handmade. Not only is the attention to detail amazing but this isn’t just some model engine, oh no, this engine actually works! The amount of noise produced is impressive for such a small instrument.
