building a 347 (diamond -8.6cc pistons), ordered total seal rings from WS6store and Mike called me today asking which rings I wanted, gapless or conventional. Seeing as I'm kinda new to the Forced induction scene, I have no idea what I need. I was hoping someone could clarify for me what is ideal. I'm going to be running a ebay GT45 (possibly sell it and buy a on3 76mm), I'm planning to run around 15lbs of boost. Tried searching and couldn't find much on the topic.

 

Most fi motors want a .28 thousands ring gap i may b a lil off tho i have my machinist than does all my blocks hand file my rings last set i hade done were that ring gap but it was intended for a lil more boost make shure the rings are a steal top ring set as well maby someone else with diamond pistons can chime in with a lil more details

 

That gap is on the 'high' side for 15# of boost. Conventional rings are fine

 

When u say conventional rings what gap do they come with and what material are they made of ive always used wiesco pistons and they come with rings
