Behind the Scenes of Gapless Piston Rings And Ring Flutter [

What are the advantages to using Gapless rings?
In this [TECH TALK] Andre talks to Keith from Total Seal Rings about their gapless rings, the design of their rings and how they work better than a conventional ring.
Covered is a brief history of the gapless ring and why we need a gapless ring when building high-performance engines in relation to blowby and leakage as well as oil contamination, or in Total Seals Gapless rings case, a lack of all these things. After all, as Keith mentions, no matter what other parts you have in your build, if your rings aren't sealing and helping draw as much air into your cylinders as possible you're potentially wasting your time and money.
Also discussed is a theory around the setup of the top rings and second ring where many suppliers and manufactures advise leaving a bigger gap on the second ring helps avoid a pressure build-up and destabilisation of the top ring, known as ring flutter. Total Seals Keith explains that while the theory holds water, it’s not 100% true as the specific set of parameters required to cause ring flutter are very rare with misdiagnosis causing a lot of confusion around the topic.
The decision process between a gapless top or second ring plus what sort of heat considerations and management you should be aware of with the different rings? With friction reduction in mind ring thickness and micro-welding along with the common causes of this are also touched on.

[@yarrdayarrdayarrda]

The cool thing with Total Seal is you can call them up and many times actually talk with Keith (at least that was the situation years ago) and he'll talk your ear off about your combo and what you can go with. I wanted to stick with conventional gap rings, and a low (16#) oil ring for a typical 400 SBC N/A drag combo, 1/16 1/16 3/16 setup. Keith recommended a set with a napier second ring and an 8# oil ring, even though I had no plans for a vacuum pump. The rings sealed instantly, and have provided years of service. What wasn't mentioned in this interview, is thinner and lower tension rings reduce cylinder wall wear, so what might require a rebore in the old days using the old 5/64 compression rings, can last more seasons or thousands of miles more in a street car with a thinner ring package. Many piston manufacturers offer pistons with these modern, thinner ring grooves.

@@tunnelportterror You have NO IDEA what you're talking about. You can't just install piston rings in a worn out engine bore and expect them to seal correct. Stop spreading misinformation and please...stop building engines in the sandbox in your back yard.

[@gordowg1wg145]

@@tunnelportterror Uh, that's a really ignorant thing to say. With a "race" engine with optimal ring gaps that are JUST shy of butting, there may be negligible difference initially. However, over time rings and bores do wear very slightly and the end gaps open up and sealing is slightly compromised - this is why these rings are almost exclusively used in endurance engines, such as NASCAR, because their design allows the seal to be maintained even when each part's gap increases. Does it work? Uh, since ring leakdown and crankcase vacuum are often better at the end of a 500 mile race than at the start, I would think so. Now, consider a "street" engine - while this means different things to different people - for one it may be a "street racer", for another a "power tour" car expected to do a few thousand miles between builds, for another it may be a stock or mildly modifies engine that's expected to do hundres of thousands of varies miles. While each of them may benefit from the improved resistance to wear compromising the ring seal, it's the last that should see most benefit.

[@pikkieduplooy9400]

love your stuff mate...devils in the details

[@Nathan-gj8ch]

I have only put rings in Honda blocks and one 1jz but all the NPR rings I have fitted said to never gap them on std bore size. The problem with proving ring flutter is that it had a catastrophic failure and there is nothing to look at after RUD. I call it "ring chatter" that's what it really is IMO. the vapor pressure that is applied to the rings makes them deflect sometimes riding in the piston grove funny/weird and they wipe on the cylinder wall like bad windscreen wipers chattering. But like you said rare thing to happen and if it happens long enough one may see zebra stripes the chattering leaves on the cylinder walls.

Should the ring pack be set lower from the piston crown for nitrous\blower applications? I have seen large numbers (.40"+) discussed on the Wiseco blogs. Seems pretty hard to do with all these pistons out with short compression heights. Subscribed.

[@kellyjensen9425]

I think the drawback is that the ring flutter thing likely isn’t BS and is a serious issue. From what I’ve read the gaps in sealing account for a minuscule percentage in performance loss. With today’s super tight emission I would think the OEMs could justify the expense considering other emissions hardware is likely far more expensive than a ring. Still though, perhaps they are expensive but still, manufacturers put out expensive cars as well where cost isn’t an issue. Are gapless rings installed in the Nissan GT-R, AMG GT, Ford GT, Audi R8, etc? I doubt they do and for me that’s answer enough.

[@darianistead2239]

@@kellyjensen9425 Yeah, because you think it's BS, it must be true🤦‍♂️.. In competition extracting every last benefit could be the difference. Not the case in production vehicles. Production cars have ideal operating parameters, they are run at a constant so don't need the benefit of being dual purpose at added expense. Just because a car is expensive too, does not mean bean counters don't try save on every component. Maintenance or Direct injection leaks, emissions when an engine wears meaning emission controls still need be in place etc etc etc heaps of reasons as to why not in a production vehicle but mainly ease, cost and catering for the average consumer would be high up in the reasoning one would assume.

yeh there's no ring flutter with a 9000rpm sprint car engine with 17:1 compression.. because at that high of a compression ratio, there's still enough blowby pressure to get past the 2nd ring, even while using a gapless Total Seal ring, rather than pressure get trapped between the rings and cause flutter. and there's enough blowby to make the low tension or standard tension oil ring work as well. because some slight blowby is what makes the oil rings work work in the first place. it's a simple concept, looking up at the bottom of the piston, from the crankcase side, blowby air pressure above the piston acts as an air gun and blows oil downward into the crankcase, and off the rings, and into the oil ring grooves, and openings in the oil ring groove, into the inside underside of piston. and that keeps it out of the combustion chamber. this is why Total Seal rings on a street engine smoke. they're really a high compression race only ring application.

Sounds like ima be blowing head gaskets all day

[@macgyverdroid]

i will try put a extra oil ring in the bottom ring 🤭🤔🤔🤔

[@sirensara6341]

I've put a lot of engines together in my time, and in my engines, the rings dont flutter around.

[@johnpena9165]

I've used Total Seal gapless rings since the early 80s and wouldn't use anything else, once you use them you'll never go back to what you were using before !

[@oggramm]

Who was the maker of these rings, I can post picture of a piston that had gapless rings all the way around and it busted a piston after 5 years at 750 hp engine components rated for 1000 76mill turbo meth injection so if these are a better manufacturer idk be interested in checking them out

[@hpa101]

Nothing last forever to be fair and there is a point where building for a higher HP than you are running doesn't actually add any longevity. In some specific cases it would actually reduce it. To answer your question though I believe 'Total Seal' is the brand Andre has personally used in a dedicated drag engine build/s - Taz.

[@oggramm]

@@hpa101 thank you I believe the builder might have ran to tight of ring gaps and under boost it eventually blew up

[@marktucker1651]

Ive been using them for over 30 years. on almost everything I build.from supper charged to air cooled vw stuff.the oil stays much cleaner.much better seal for way way way longer time. it is best to have a accumulator groove if possible even a tiny one will help.what else does a accumulator grove do??? lightens the piston!!! there are many morons that think these are just for race cars...or they are over kill....well, you cant fix stupid.

[@jockellis]

Can I get these for a 96 mm piston in a 914 and do you know what it would cost? Also, any idea what the extra power might be?

[@marktucker1651]

@@jockellis contact total seal but Im pretty sure they will have them or cn make them. usualy $85-130 for 4 cylinder, for them sets. alsoI used to send them rings for them to remachine into total seal rings many many years ago for the ones they did not make at that time. but you really need to start poff with a good ring.not the china crap or other low quality rings. as for power, not a lot, but the oil stays so clean, the oil temps seem to be lower, less oil leeks if any at all.they are well worth the $$ spent. also if you have new cylinders they need to be honed finer,or atleast the "Tooth " knocked off. witch you can do by hand with 400 grit wet/dry with soapy warm water and our hand in the cylinder hand honing just about 1 -2 min each with the same pattern.use the palm of your hand. that should take the tooth off(sharp edges that eat up rings) then throughley clean a few times & lightly oil .never oil the rings. wipe the oil out of the cylinder with clean paper towels, the towels should come out clean if it does not you havent cleaned it enough. re oil and wipe out with another clean ppaper towel. install rings properly I install into cylinder, then install cylinder & pin& pin clips/ buttons,be sure to oil wrist pin,wrist pin bores, rod pin bore & lightly oil skirts.no oil on rings as you have pree oiled the cylinder walls & wiped off exsess with paper towel.thats all the oil it needs.

@@marktucker1651 Mark, thanks for all that information. I’ll do it.

[@jockellis]

Oh, I’ve got the AA piston and cylinder set.

[@marktucker1651]

@@jockellis thats what I figured, get the compleate set of total seal rings for them. and be sure to knock the tooth off to make them last. I have a sunnen hone but it takes a good amount of time to do them with it, mainly it's good for used cylinders or increasing the clearance, a good hand hone wash is usually what I do on new cylinders that have the right clearance. not just draging the paper across it you need to add some pressure with the palm of our hand. not hard to do at all.unless you have extra big hands like I do, then no need to add pressure it's already there. those sharp edges from the factry hone job will eat the rings up, they will also wear off and it all gets either imbeded in the piston skirts witch then wears out the cylinder walls or some of it gets into the oil and starts eating every thing else& cloging the oil filter. these vw engines do not have to be disposable like most people build. my 2028 had 80000 miles on it trubble free with an extra 50000 miles on the crank,main bearings,camshaft&heads before I put it all in a new case with new bigger pistons. and it still ran perfect when i sold the car 4 ears ago.always synthetic oil used after the first 3 oil & filter changes in the first week. 4th oil/filter change it got a syn blend for 1 week then full 5-20 full synthetic name brand oil. it was driven like I stole it every day I owned it( it was my daily driver) duell webbers 44 idf. .55" lift cam, wedgeport heads 1.34 ratio rockers,10.4 cr. 93 octane pump gas. it was quite fun. the new owner loves it.

[@adamknight9535]

shame you didn't have time to look at the other rings total seal do

[@shorty808100]

If there actually gapless they would break as the cylinder got hot and the rings expand so a 0 gap ring isn’t possible

[@hpa101]

How gapless rings work is explained in the video. You won't regret watching it, I promise. It's a great interview - Taz.

[@Albert87nl]

i can see posts back to 2002 of this.. why is now only propperly interviewed lol bit of a underdog until today?

[@hpa101]

In the interview dates older than that are discussed, it's worth a watch - Taz.

[@louf7178]

I would rather see these named lapped rings. The rings do have a gap.
