Barry,

I don't want to put words in your mouth, but I get the impression that you feel that traditional rings do a good enough job. I'm thinking the positives minus the negatives on gap-less isn't an overwhelming reason to go fix something that isn't a big problem to begin with.

For high performance applications - certainly racing applications - engines don't typically run long enough to wear the bores a whole lot. I have pulled some high mileage engines down that the bores were so worn that a 0.040 over bore wouldn't straighten the bores up and tossed the block. It never occurred to me back then to stick a ring in and measure the gap, but I expect the gap would have increased by .010" to .015." I believe that the gap-less ring would be better at the end of a street engines life. Not that that necessarily makes a good case for there use.

Your thought?
