Title: VW radial engine Post by: cameron shorey on March 31, 2014, 21:26:05 pm How about a radial motor for an ultra light aircraft? 7 stock cylinders makes what? Approx 2800 cc. Radial engine made with VW parts. http://www.youtube.com/watch?feature=player_embedded&v=SyRJeZ6s8uM Title: Re: VW radial engine Post by: Zach Gomulka on April 01, 2014, 07:20:54 am That's fookin incredible! Sounds great, love the exposed valve train.
Says 2086cc at the end. That's less than 300cc per hole, 85.5x52? I wonder why so small?? Title: Re: VW radial engine Post by: Zach Gomulka on April 01, 2014, 23:15:23 pm Guess I'm the only one interested in this?!
On second look the cylinders appear to be factory 40hp. Most likely 77x64, factory VW bore/stroke. Title: Re: VW radial engine Post by: Taylor on April 02, 2014, 01:06:38 am This is really cool!

Title: Re: VW radial engine Post by: cameron shorey on April 07, 2014, 19:12:17 pm You can find a nice computer animation of a radial engine at Wikipedia. Shows how the cam and valve train work. Radial engines can't use a regular sump type set-up, because half the engine is upside down. They usually use a dry sump type system, where one pump pushes the oil through the crank, to the bearings, and a second pump scavenges oil in the block and pumps it back to a tank.
