I know David Vizard is a big proponent of them, but the debate on SpeedTalk has never been resolved to anyone's satisfaction.

Some folks say they see small power gains.

Others say there's no power benefit, but the engines "stay fresh" longer.

And others, like RAMM, have reported oiling issues; he's NOT the only one to have raised this issue, for anyone who thinks he's an outlier on this subject.

I don't have an R&D budget to prove/disprove their benefits to myself. Since my own limited findings have been inconclusive, I'm using a more traditional ring pack now.

To the person who asked if I liked Napier 2nd rings, I don't have any miles (only dyno time) on the engine to see how the oil consumption is. What I do know is that GM switched from the old 2nd ring design to Napier 2nds as part of their "fix" (or mitigation?) of high oil consumption with certain LS engines.
