Anyone used gapless rings?

Has anyone used gapless rings on their engine, my engine shop says i'll gain a few horses and it's a better design than standard rings. It may also help prevent oil useage which 347's have a reputation for.

Re: Anyone used gapless rings?

you will get a better seal, but the difference is small so to speak.

"may help" dont expect it to, If the 347's gudgeon pins encrouch on the oil rings, like some strokers, that is the cause of the oil consumption.

if you are chasing power then they are worth every cent.

i was told the gain would be small, about 5hp or 10hp? they were more concerned about it helping make more power than control oil consumption, i just thought it may help a little in that area.

Brian Adams.. Copy and past

As for ring gaps these also seem to change by the year, remember a year or two ago gapless top rings were the way to go. Now they cause high RPM flutter and sealing issues.

The current concensus is to run the second gap slightly larger than the top, .003 is what we usually run.

Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!

Dont use them. Every second person that uses them has major oil burning issues.

Thanks guys, i've decided to use normal rings, i was told today they aren't the friendliest on bores. So the 10 hp they are worth is not really worth the hassle.
