Having the extra cylinder pressure should increase hp but how do they expand when they get hot? How loose would you run the piston to cylinder tolerances with those? I wasn't comfortable not knowing the answers to those questions and how they would handle the heat. Maybe I'll try them on my next build, but for now, I just opted for the old fashioned Mahle/Cummins rings.

Out of curiosity, what are your thoughts on them?
