randroid Posted September 23, 2012 Report Share Posted September 23, 2012 Gents, It is rare that I get the opportunity to hijack a thread before it gets a single reply so please allow me to jump on this one with both feet: Around 1970 there was interest in machining cylinders in an oval pattern to accommodate an extra intake valve and using porcelain pistons and sleeves to allow for no rings. I've always assumed the machining costs would be prohibitive but that's never been a great deterrent in some racing circles and the "Ring Free" slogan got me thinking about it. Tell me it isn't true. -Randy Quote Link to comment Share on other sites More sharing options...
greg g Posted September 23, 2012 Author Report Share Posted September 23, 2012 Randy I looked up the Ring Free Racing team and found a similar picture with a caption. Was it rign free motor oil or because all the ladies were single and ring free??? Rosemary Smith and Smokey Drolet drove the #78 Sunbeam Alpine to 30th position while Donna Mae Mims, Janet Guthrie and Suzy Dietrich drove the #80 Sunbeam Alpine to 32nd position in the very first Daytona 24-hour race in 1966.

oldodge41 Posted September 23, 2012 Report Share Posted September 23, 2012 (edited) Honda raced oval piston engines in motorcycles in 1979. See the technology here. http://world.honda.com/history/challenge/1979pistonengine/index.html Great quote associated with these engines. "When I look back at it, I'm not sure if we were experimenting with cutting-edge technologies or obsessed with foolish ideas," recalled Toshimitsu Yoshimura, an engineer involved in the development of the NR500's oval piston engine.
