1. Paper V8 Engine

This fully-functional V8 Engine was made entirely from paper by Yeesjob, with the exception of its internals. It sports many moving parts, including a compound crankshaft, a rapid cooling fan, and a complex compound gearbox etc. The engine is powered by 2 x 1.5V D batteries and weighs 6.6-pounds.

2. Quarter 4-Cylinder Engine

Built by George Luhrs, the “Quarter 4-Cylinder Engine” is touted as the smallest of its kind. It took him approximately 600-hours to complete and no details were spared during the build, as you can see from the images above.

3. LEGO V8 Engine

Yes, an auto enthusiast has built a working V8 engine using just LEGO parts. This tiny engine peaks at a maximum of 1780 revolutions per minute, which was made possible by adding timing gears in the rear to prevent torsion in the crank and cam. Currently, it’s running in a double cam setup.
