Paper V8 engine

Maybe not so suitable for A-C but an amazing work of art to behold:

 

 

"This project by YouTuber Aliaksei Zholner is on the smaller side, but no less impressive. This tiny V8 engine is small enough to fit in your hand, with a piston stroke of just 6mm and cylinders with a 5.5mm diameter. And it works! Obviously it doesn't actually run on gas considering that it is made out of paper, but it hums right along when hooked up to a supply of compressed air. It even sounds wonderful when it's doing it."

Now if you like sweet engineering but must have the real thing here is the dyno run-up of a quad turbo 12.3 litre 5000 horsepower V16:

 

 

C'mon Jabiru, sign these guys as consultants.

Great engineering but way too much power for the street. I'd still like to drive it though :)
