Click on the image for more shots of the LEGO V8 engine

There has been a huge amount of interest in air powered cars since MDI began showing its creation off a few years back. There is a lot of engineering that went into these vehicles to make them as practical as possible and to offer a good deal of range. So, we were pretty darn impressed by the efforts of a small group of LEGO enthusiasts who have been making working engines using nothing but LEGO products. The engines are powered by compressed air, and actually power the vehicles that they are placed in. Want to see an example? Click here to follow the build process of one totally operational V8 engine made from LEGO blocks and components. As you'll see, the builder has decided to go with a simple pushrod design after testing various overhead cam styles. At present, the engine is running at over 1,700 revolutions per minute. Watch a video after the break.
