Gapless rings

[Jackson1320]

I have only ever built one engine with gapless rings. I have heard a few horror stories about the gapless rings. I have also heard how awesome they are. Anyone have a opinion, advice, information

Gapless rings are for guys building 305 chevys in there dirt floor garage with a stone hone from the 50's they bought at a garage sale with used tranny fluid as a lube.

running Alky.

That makes no sense. If they are better then they are better if they are worse there worse.

I would not expect gapless rings to make more power but maybe control crank case pressure

If gapless was so great every manufacture in the world would be using it. But they don't. The wear is unusual, The wear is accelerated (definitely not a street ring), the two piece top ring one of ring usually get distorted which leads to my second point. Sure it'll take a little longer to leak down, or if you're run 100% alcohol/methanol and is for strictly a race engine by all means go for it. I won't. But you can.

Skip gapless rings. If you're looking at building your own motor, only thing you'd need to do is take your rotating assembly to the machine shop and get balanced. I'd also have the machine shop clean the block and the cylinder walls. You could spend a few hundreds bucks on a ring cutter (proform is legit as I have one and works well). But I'd spend 1k more and take to a machine shop and have them do everything for the comfort of knowing it was done right. We use TKM, we've been using them for about 10 years now and have had some killer motors.

We've done a few simple motor builds in the shop for standard builds for guys not looking to kill a budget.

Absolutely. Just ask Bryan Luna. I guarantee that 190mph TKM coyote doesn't use gapless rings.

Thought he used H squared

I have yet to see where gapless rings work with any modular ford. Just run the std ring pack unless you are tying to do some trick stuff and want to tear it down again to optimize ring gap.

You know these things for a fact or you heard/read it?

I don’t understand what you mean. Gapless rings will work just fine in a modular engine. Almost every piston manufacturer uses a ring pack that is different than the standard rings. Seams like you are just giving your opinion but don’t actually have any experience

It is stupid to have a machine shop prep your block. It’s the same price to purchase a new one.
anyone building a stock or close to stock coyote is a fool. You can get a new shortblock for $1800-$1900. You guy’s really don’t know what you are talking about. You sound like the kind of person that pays other peopleto do everything and then talk about your build that someone else built

Maybe not but that doesn’t mean that it couldn’t
