opinions on total seal piston rings

[stonebreaker]

Going to freshen up my engine. Was wondering if anyone has tried Total Seal's gapless piston rings, and how you liked them?



Thanks in advance,

My engine builder doesn't think they are worth the price. He has a 750hp small block and tries all the new crap out. He said he saw 0 difference in gapless vs properly gapped rings.

There was a guy came in that wanted the gapless rings put in his motor. My engine builder told him that he does quailty work and won't chance having an issue with an uncoventional part.



As far as I know once the rings heat up, the gap starts to close. If your running gapless rings than there is no space for expansion. Maybe I missed the reasoning for this



Space.

The gapless rings are actually two thin rings that fit in the top groove. Each one has a normal gap, but you install them such that the gaps don't overlap, thus a "gapless" ring.





Pease, what about longevity? One reason I'm looking at these is that as normal rings wear, the gaps open up.

I tried them in a big block setup and they wore my bores a lot in just one season. To the point that I needed to rebore the block. I would not reccommend them. Also I saw no performance gain at all.

I think that says it all. And, looks like others have info that backs up that statement.
