I can't find any information about this piston ring set. Summit:

Is that set OK for 350+hp daily driver?

Should block be prepared and honed like for plasma moly rings (finish with 400 stone)?

Or is this set junk and should I go with plasma moly ones?

How long will be break-in period with these cromemoly rings?

I don't wanna rebuild my engine in 2-3 years, so I need ring, taht are durable.

Thanks!

They'll work fine for that.

These are not the file-fit type.

Break-in should be 500-1000 miles.

Actually, the hard chrome faced ring sets may take a little longer to break in, but are typically longer wearing than other types of cast rings. You might use a little oil at the beginning, but should have good compression sealing for a long time thereafter. The oil control rings are still stainless steel rail type, IIRC.

personally i wouldn't use them, not that they're bad, or good, i like moly or plasma moly rings for just about everything.

But how should be bore finished? With 400 stone like for plasma moly's?

radiateu2 · 01-13-2003, 05:56 AM

actually the bores are supposed to be finished finer than that. They are good rings for like dirt track racing. From what I here they take forever to seat and burn oil. Atleast that was the research that I have come across.

400 grit stones work fine for those.

People use those rings for an incredible number of engine rebuilds. I've used them myself a time or 2. No problems, no excesively long break-in, none of that. Proper assembly goes a long way toward insuring against such things.
