Howdy,
There were some questions in another thread about these, and I had side tracked the other thread too much already.
People have seen the little video clip of taking a piston ring, and twisting it 90 degrees, The ring didn't break because it is ductile. Way back when I first started to dabble with aftermarket products, I went on a couple trips over yonder and talked to some very interesting, and intelligent individuals.
One of the most interesting was Lee Ho Chia. He had worked for Toyota, and Honda Racing before he retired and started his own business back in his homeland of Taiwan. When he started in on ductile rings, I'll have to admit my brain didn't want anything to do with that thought. As I listened, it didn't take very long realize his depth of knowledge on the subject was awesome. Every time he paused to see if I was following his drift, I was so engaged I could only give a nod, and maybe a involuntary grunt.
We did considerable testing with these rings and, they performed as described. As far as I'm concerned, these rings have every advantage over conventional rings except for one, that being longevity. We chose to do our testing with firewood cutters that were putting food on the table with there saws. Homeowners are tough on there equipment but, they do the kind of hours we were looking for. Timber fallers around here put some hours on their equipment but, they treat their stuff to well (premium fuels, and oils plus regular maintenance). So with our test subjects, the rings were giving about 400-600 hours before the rings started losing their snuff. The grooves in the rings were still there but, they become more of a line rather than a groove. These tests were done with high quality petroleum based mix, and regular unleaded. I personally know of some saws around here that are on synthetic mix that have many more hours on them but, have lost any kind of documented time sheets. I figured with an approximate life span of 500hours, a guy would be in it around, or by then just to clean the carbon out.
I think we were on the AS when it happened but, we did have a shipment come through with non-ductile rings, and the failures were off the hook. I believe that was back in about ought 7. It was I financial fiasco, and a real live learnin' lesson. We've been trying to live that down ever since.
Regards
Gregg
