Here’s a write up some may find interesting. If you’re curious about the pro’s and con’s of different port geometries and/or how flares impact their performance, take the time to look this over. It was published by Scott Hinson on his Facebook DIYRM page. He’s one of the more knowledgeable guys I know in the DIY community and what I like most about his work is his scientific approach to what he is discussing.
