midgetracr Posted May 8, 2011 Share Posted May 8, 2011 Interesting. There was an effort years ago to make a 4 valve overhead cam 4 cylinder engine out of composites for Midget Race Engines. It never got going. Sooner or later someone will make it work. Link to comment Share on other sites More sharing options...
turboeric Posted May 8, 2011 Share Posted May 8, 2011 I remember reading about the Polimotor effort years ago in either R&T or C&D. I'd assumed the idea had died, but apparently not. Link to comment Share on other sites More sharing options...
danilo Posted May 8, 2011 Share Posted May 8, 2011 More Vaporware :-) Like Ponzi schemes a seemingly never ending supply :-) Years..ago there was some effort to make utility motors (mowers/chainsaws/weedeaters etc) from plastic extrusions. Started as entire motors soon devolved into partial plastic components then finally air shrouds. Just wasn't much of a price difference from metal and the materials were not as stable 'as advertised' . Link to comment Share on other sites More sharing options...
