Piston Ring Spacers

[Alan Roehrich]

Rob, I'm not saying you can't run the super thin rings and make it work. Keith will certainly help you as well, regardless of which set of his rings you buy. I would want to start with a clean sheet of paper to run the sub 1MM rings. You can find some power. But I'd want to start with a fresh block and pistons, done the way Keith tells you.


Dave, I'm not sure I'd spend any money on a set of pure race rings just to put them on a set of cast pistons. I seriously doubt the cast pistons are going to have the precision ring grooves necessary to make really good rings work well. The flip side of that is that if you really have more than 10-15% leakage, even on a set of stock cast pistons and rings, you have serious problems, and I doubt buying an expensive set of custom rings will solve them.
