Lego Pneumatic Car Engines Now For Sale!S

Remember the crazy 1440-RPM V8 engine built from Lego Mindstorms parts we showed you back in May? Now you can buy your own from LPE Power's recently opened online store.

Nicjasno, the original creator of the Lego Mindstorm V8 is now giving you the opportunity to purchase an inline-3 or inline-4 version of their amazing little engine from their site's sale center at LPE Power. They promise that V6 and V8 models will soon follow after they build up enough business. We’re hoping that business picks up quickly because we want the V8 model. Now.

The lego-loving folks build the pneumatic engines using the Scotch Yoke of operation in order to keep size to a minimum, and to maximize usable torque, giving better overall power output. The 2000 rpm inline-4 model features a cross-plane crank, a gear-driven valvetrain and a side-mounted dual cam with one valve-per-cylinder. The inline-3 model features a similar setup but delivers 600 rpm more.
