World tiniest v12 engine

[lethe]

Saw this a while back. Makes me wish i had gotten into the machinist trade.

 

[cop on my back]

I made an aero V-8 engine a years ago. It is 3 1/2" long. That V-12 is very cool, but it doesn't run on fuel, it is just on compressed air.

id love to have a tiny v8 like some of the ones ive seen, actually runs on fuel and all the usual workings. put it in a little drag car or something and see how fast itll go
