Roger on all of that. While that article was about Total Seal rings, I have prefered Mahle rings for the engines I could get the sizes for. Mahle is the biggest ring manufacturer in the world and I like their top ring port design better. We have been using 2 ring pistons with low tension rings for about 10 years now. The hp gains have been published by various authors many times and are well worth persuing. It should also be noted that there are several things that go along with narrow low tension ring packs that are essential to realize the maximum benefit from them. You can't just put them in any engine and expect big numbers.
While discussing all of this, it should be remembered that most of these parts are for all out racing. Maybe some day some of the developments will trickle down to 100K mile street engines.

By the way John, is there a "fiction" reduction also? LOL (just kidding)
