anyone using gapless rings for FI?
anyone using gapless rings for FI? just wondering if there would be an advantage to using gapless top ring for my rebuild? Is anyone using them, good or bad expieriences?
I used them on my last rebuild but only got about 300 miles out of the rebuild ;( not the rings fault. Picked up some power def compared to my other rings. I think the only downfall is they will wear faster

In mine it was the top ring. It's a stainless 2 piece affair to create the gapless effect.
But the 2nd and oil rings are just conventional
As long as they are used correctly, bore finish is good, then I see little reason why they would wear faster, and certainly no reason they would score the bores.

What benefit could a full circle seal offer against a seal with a gap ?
I think the benefit is obvious, even if in reality it it is only very small.
Normal rings dont have a gap because they want a gap there, it's simply required by design.
Obviously gapless rings do still have a gap, but by design the 2 rings overlap so where the normal gap would be, there is still a solid piece of ring passing over it.
If there really is a measurable difference, it would be incredibly small. Most likely less blowby, and less crankcase pressure.
Power.....doubtful it will really make any difference
