Low Tension Rings: By the way, I'm not talking about "low tension" oil rings in my usage of Ross pistons and metric rings.

While these definitely have applications in racing and performance builds in general, they also require an engine that is effectively "sealed", usually has a vacuum pump and also probably has a full dry-sump oil system - and an oil pan designed with scrapers and windage trays, etc.. The result is a definite increase in HP - but not exactly a "traditional" setup, or one that is easy on the wallet! LOL
