How Much DIFFERENCE Can Piston Rings Make?

[@autonomous_collective]

Note:🏁 1) Reduces Temperature 2) Power goes up 3) Less ware and friction 4) Cleaner oil 5) Variable modern hardness coatings 6) Water Temps lower 7) Plateau hone is best 8) Cost more? Yes, but its well worth it! Love the science, physics, and technology that goes into these awesome rings!

[@thenomadrhodes]

How long will it LAST is the real question? Is it going to go hundreds of thousands of miles?

[@davidphillips3953]

This is great info for race engine builders but what about guys building engines in their garage hoping to get 100,000 miles out of one? Many new car manufacturers are having major blow by and oil consumption issues with ultra thin low tension rings on really short pistons... how are we sposed to know if our local machine shop did our block with a good hone job? We can't test this stuff... do you think we should be stocking to thicker rings if we have no way of knowing what they are doing as a safety margin for our engines?

[@1d10t.]

Exactly. Love a powerful motor, need it to work long haul as a daily driver.

[@saab9251]

New OE engines have substantially opened clearances for small turbo engines to account for piston expansion under load. We’ve dropped oil viscosity substantially which tends to stay suspended in vapor form in the air inside the crankcase. Combine this with a metered, continuously open orifice instead of a PCV valve that would vary depending on vacuum conditions and you have a perfect situation for vacuuming oil out of the crankcase on every new engine. OEM’s are getting worse at making cars every year now.

[@PSA78]

Car mfg quite often cut corners to save money, if for instance the oil consumption gets too high then they start using stress plates, measure more carefully etc. I used to work with OEM engines and I've heard behind the scene stories from a lot of different mfg. Point is, ask the shop what they use in terms of equipment, and don't let anyone talk you out of needing it (including your wallet). 😉

[@jonathanshaw8868]

​@@saab9251 ring end gap is to allow for the ring itself to grow and not chafe the cylinder wall to death. But you are right about everything you wrote.

[@jonathanshaw8868]

Engine builder here, yeah low tension rings are junk, unless you have a trailer queen car that's only going to see track use, forget it. For the average guy, I will gladly sacrifice a few hp for life span.

[@scotteric8711]

I used total seal gapless, file fit rings on an otherwise stock rebuilt 1969 Cadillac 472 engine, and it made more power and torque than original. The engine had a stronger vacuum signal to the carb as well!

[@sanger440]

It would have been nice to see some blow by data on this test also.

[@chrispompano]

Crankcase pressure?

[@edsmachine93]

Thank you Lake, Shaver Specialties, Total Seal and everyone envolved. Very impressive tests for sure. I was surprised to see the oil temp so high in the first test. Nice gains all the way around. Have a great weekend. 👍🇺🇸👍

[@TotalSeal]

Our pleasure!

[@simbanugz2906]

I know i will probably get laughed at but when I built my 12 3.7 engine before going procharged. I picked up 6whp/9ft going to total seal rings on my manley pistons. What I was more impressed with was how little blow by Ive had running my procharger. 444whp on 6 psi. Through a 6r80. I used hasting rings before total seal it was night and day difference on blow by.

[@simbanugz2906]

Guess I should or said 12 mustang

[@ihateemael]

but was the blowby reduction just due to new rings?

[@bleach_drink_me]

Nothing wrong with that, coming from a guy with a built twin turbo vq35de in a G35 which is equally laughable to some.

[@MarkShinnick]

​@@ihateemaelIt's the usual consistent result.

Awesome work TotaSeal. Great videos as always Lake Speed Jr! Cool stuff!

[@keithstudly6071]

The 1/16 rings were standard for a long time. Why wasn't the oil temp as high as it was this time. I heard you say the oil temp was higher than you had ever seen before in break in. This leads me to believe that something was not optimum in the ring instillation for the larger rings or they would not have been so much hotter than they were. Is it the hone finish that give the wider rings trouble? I wonder how we would have lived with rings that create so much friction for so long? The greater area for the ring face should make for a better hydraulic wedge between the cylinder wall and the ring. Ring flutter and blow by can also produce heat. I have to believe the wider rings were not working as well as they should have been. Also the OME engines have been going to thinner rings for improvement in fuel economy but this has increased the oil consumption especially in engines with some miles on them. Are these rings reducing engine life? I've heard people who do service say that oil consumption is up on recent engines.

[@benoconnor6355]

Thats $20 - $22 per hp. You would be hard pressed to find a better HP per $ ratio.

[@robertwest3093]

Yay finally a real piston ring test. Dyno comparisons for the 5/64 rings vs ultra thin rings is scarce.

[@robertwest3093]

Lake, it’s like you’re reading my mind! I look for these kinds of comparisons on the web and their really isn’t a whole lot.

[@billyarsenault1970]

Jeez Lake I never known anyone who insists so much on making everything ultra perfectly clear for all us poor suckers like you do. Thats very considerate and I appreciate all the extra work.🤘🏻

[@ryandeweese363]

Great information about ring selection!! When I upgrade my dual plug 4.7 to forged pistons, I'll deff be upgrading the ring as well... Was thinking about getting the mahle power pack pistons but nothing listed for a sub 4" bore... 3.71 I gonna be difficult I think as most v8s run 4+. I did note mustang 4.6 has similar sized pistons. Thanks for the heads up on the plateau hone too, sure that works alot better than the old ball hone

[@chrispompano]

Well that ends that....a Delorean's PRV V6 uses 3.58” (91mm). So nothing less than 4"?

[@robertwest3093]

Finally a fair ring comparison that shows the real difference in power. I knew that the OEMs weren’t going to thinner rings for the hell of it. Just imagine if the thicker rings HAD been the 5/64 package? Joe Sherman always said that thinner rings were worth 30 horsepower going from the thickest to the thinnest.

[@UserUser-zc6fx]

I have been binge watching your content this week. I have learned an enormous amount so far. Thanks for sharing.

[@TotalSeal]

Thanks for watching!

[@krusher74]

We arnt all 400hp V8 centric viewers, its would always be nice to hear a % improvement. Then we can maybe extratrapolate the rough benefits to our own power source when considering which rings to buy. (The power graph is at 19.33) , 4% increase? would you expect engine of 100hp and a 1000hp to get a similar 4% gain? would a 4 cylinder have more or less to gain than a V12?

[@thatmand4542]

This is awesome, I never really looked at it that way when it comes to the rings but it makes perfect and obvious sense now ! Definitely a factor to add in when it comes to my next engine build, that being an AMC stroker for my daily driven jeep Lj! Gonna have to see and spec out a piston and see what i can find cause i cant custom order pistons and get em next week.....

[@brentonk461ismylostaccount]

That's great for Money no object Racing.. I used total seal in some of my Engines, and have no quip about them, but for my budget built 14:1 compression pump fuel daily driver sbc combo, I'm still going too choose the $40-$60 ring set and pocket the $540 change and use the money elsewhere thanks.

[@chrispompano]

How can you run 14:1 on pump gas? What's the secret?🤔

[@brentonk461ismylostaccount]

@chrispompano A Life time of studying Engines, and my Own Research and Development.

[@autumnjeserich2689]

Static compression isn't directly related to cylinder pressure. 14 to 1 will even run on 85 octane with no detonation if your intake valve closes late enough

[@bigboreracing356]

I ran a B&M 420 Mega Blower on a iron head 11.5 to 1 compression 468 Chevy using 93 pump gas. I simply used a loose converter in a light weight car ,3.73 gears big cooling system, loose bearing clearances to keep oil temp down and a on the fly timing retard. When I got called out I switched to C16 and backed the timing off a little. Another trick is to install a water Meth injection system but becareful because those can fail if you dont maintain them. It is easy to cruise around on pump gas with higher than normal compression when you use common sense.

[@brentonk461ismylostaccount]

​@@bigboreracing356 Sounds alright, I'm sure it goes well, but I was talking about my daily driver combo, drive it too the track, drive it too the shops, drive it in peak hour traffic 2-3 hours do some runs at the track drive it home on pump fuel 327 small block 14:1+ static compression ratio on unleaded pump fuel, Not oxygenated leaded Race gas, no octane boosters, no water methanol injection Naturally aspirated No power adders No turbo No blower No nitrous 10 second quarter mile times, full weight four door sedan @3400-3700 lbs And probably capable of 9's in a stripped out Race Car on Race Gas.

[@magnusdanielsson2749]

If planning on using those thin steel rings you should make sure your machine shop have to tools to do a proper plateau hone. That means they should at least have a four stone diamond hone and preferably a six stone to be able to get the bore proper straight and produce the plateau needed for those rings. The older more common two stone hone with two supports wont be good enough.

[@jeffwooton7138]

As always, great information, and great presentation. I'm truly impressed with this new ring design.

[@aussietaipan8700]

Many years ago I purchased a HQ Holden Monaro Coupe, this car had a tiered old 308CU V8. I had it rebuilt with a balanced crank, rods and new pistons in 1987. The rings the engine builder used were chrome molly, the top ring being 1.8mm thick. Instead of the top ring being 1.8mm flat, it was gas port dome shape. The rebuild engine ran like a cat escaping a dog and best of all, in 2024 it is still running great. Much less engine wear, lower oil temp, less friction. This car runs a 13.6 quarter mile on an otherwise almost stock engine.

[@markwanc1103]

Just great video's from you guys. Both of you would be an absolute riot to work with - easy to see you have fun while you are doing development testing. I always learn a ton of information from your well put together videos.

I rebuilt a 283 Chevy engine back in 1974 when I was in the military. I cleaned the engine block and parts with what the military uses. I don't know the name of it but when the block and parts came out of the cleaner they started rusting instantly. coated them with oil fast. I put the engine together and ran it 4000 miles and the oil was as clean as when I put it in. I sold the car so I never did find out when the man changed the oil. Never got to use that cleaner again and the rebuilds went back to normal. Lol. It was proof the way the parts are cleaned makes a real big difference.

[@davidraezer5937]

I’m blown away guys! I would like some details of the honing process for this ring pack. I’m assuming the gas porting along with the special plating process on these rings would make for a long lived engine. Especially given the lower cylinder bore wear. OEM manufacturers use a thinner lighter tension ring pack but I doubt they have the porting and special plating process you have due to the cost factor. All it takes is the consumer to extend oil changes and use the wrong oil and you have a recipe for disaster in any modern engine.

[@billlittle4285]

Been using.08 mm in my super stock Olds engine for a while,used them in my SB as well,ran the fastest with a ball hone and a steel ring that had been in the engine for 2 ball hones, that's cost-effective , can i get a discount on my next set, August says i can, thanks for great rings and great service!!

[@teagreen2220]

If you use thinner rings with gas porting on the rings is the piston clearance more important and particular? Will a loose piston with thinner rings cause more damage than a loose piston with thicker rings. For a race application it won’t matter but for longer runs like a daily driver, is there an issue with incorrect or loose pistons running the gas ported thinner rings? Will they break easier?

[@partsshooter]

2 things I'm skeptical about regarding this power change that likely increased the power was the margin for human error/variable and the coolant concentration. Human error meaning, we could've accidently been off .5 degrees of timing with the distributor assigning the power contribution to that. This do have an influence on temps also Coolant, well... assuming the water pump isn't electronic, adding more water will cut resistance with less stress of the engine. That's similar to oil type of 20w50 to 10w30 at the crank fighting cut resistance. I'm not disagreeing totally those rings didn't do anything but that margin was more significant than I'd imagine. I was giving it an 8hp gain. One guy with the top comment addressed alot of what I was thinking dealing with these 2020 vehicles and their propensity to ingest oil from a long term perspective concern. However, carburetor engines got around 30k miles to our 100k miles today 😆. Yes I'm talking shit about you guys who like carbs. But the consistency draws my concern because we humans touched it. Example, I'd have better confidence if this was timing chained with ignition coils, knock sensor, and coil on plug, etc. I got my money on the output realistically being lower to what's claimed to what most of us was projecting. But I'm not gonna ever claim it's not gonna add power

[@davidreed6070]

[@davidreed6070]

I believe,it doesnt matter what else you do to your engine,if the rings dont seal, it wont make the power it should by a substantial amount.

[@mosesadk454]

Back in the mid 70s I paid $40.00 for a set of Hastings cast iron rings for my 68 400 GTO. Never had a problem.

[@VintageEuropeanSpeed-f7e]

You have to be very cautious with low tension oil rings guys, especially the oil rings. Oil consumption can be an issue if you don't balance that correctly for whatever particular engine you're working as they all have specific needs. I build exotic engines, vintage Ferrari/Maserati/Lambo, and the oil ring tension is very sensitive. We went with a 2.8mm a few times with I believe around 13lbs tension on a few engines and they consumed way too much oil, swapping to standard 15-16lbs 3mm oil rings on future builds solved the issue.

[@paulspee2968]

Great information guys. How will these rings perform in a Nissan VQ35DE Rev-up, which is notorious for piston ring problems? Thanks.

[@TheDynotuner]

GREAT proof for all the confused & non believer's! I can tell ya for a fact our UOA's are always better with your ring packs. And that's even before the new hone preciseness... 👍🏽👍🏽 See ya soon @ PRI

[@jefffanning2799]

Phenomenal! Firestone question. Will I be able to get similar piston rings for a 1.7L watercooled VW motor?

[@stickman-1]

The sealing of the combustion gases inside the cylinder and not going around the rings also would reduce the temp of the oil. You could prove this by putting an shielded air temp sensor in the crankcase to measure the temp of the air in the sump/block.

[@PSA78]

Even on a street/daily engine that price (rings + quality machining) is probably payed off pretty quick on fuel consumption as well.

[@BigEightiesNewWave]

When I got into NASCAR, because we had THE only west coast track, RIR, and I saw all kinds of racing there, not just NASCAR, they used Perfect Circle piston rings. Just looked this up now! "Perfect Circle piston rings are now essentially known as MAHLE piston rings, as the Perfect Circle company was acquired by MAHLE and the brand is now marketed under the MAHLE name, particularly for piston rings; meaning if you're looking for "Perfect Circle" piston rings, you're likely looking for MAHLE products today"

[@ssswdon]

This is good info. Did you assemble a video with boosted? Cuz I'm sure they'll break down those o-rings to become like so flat in tension pretty quickly

[@saccaed]

19:31 for overlaid Dyno plots. Would be interesting to see the same test on another engine that has very different bore/stroke/piston count. Trying to work out if its one of those things better thought of as absolute gains or percent gains. Either way that seems like an alright way to gain an extra mpg or two for road trips.

""Grey Rock" brake linings are still available today, manufactured by Haldex, and are considered a well-established brand known for their high-performance and stability in heavy-duty vehicles, particularly trucks; essentially, nothing significant has happened to Grey Rock brake linings, they continue to be a prominent option in the market; their legacy of reliable braking performance remains intact"

[@mathewboyd3746]

Is this gas ported 0.9mm ring set available for Chevy LS1 engines with 99mm or 100mm pistons? Is a custom piston required to accommodate these thinner rings? Where do I find someone to do the correct hone for these rings in California?

[@chrispompano]

Special Coated Rings, hmmm! 😁 Did you guys buy it from the guy that Jack bought his bean stock beans from?!😂 Maybe I should use a Hewlett-Packard 5710-A dual-column gas chromatograph with flame analyzation detectors on your magical coated rings🤔, but if Anyone really wants a Zero Friction Coating, send them to be Diamor coated, now available in the U.S. The scentist from the Fraunhofer Institute for Material and Beam Technology IWS in Dresden had succeeded in producing hydrogen-free ta-C coatings carbon applied by Lasr-Arc . Diamor® is the hardest and most wear resistant type within the group of diamond-like carbon materials. Diamor®, scientifically classified as tetrahedral amorphous carbon (ta-C) is purely composed of carbon atoms with a majority in sp3 atomic bond configuration as found in diamond. It is not only renowned for its exceptional hardness but also exhibits a low coefficient of friction and chemical inertness. The high hardness and low friction of ta-C coatings in conjunction with biocompatibility and chemical resistance are particularly suitable for: Components and parts in automotive and mechanical engineering, e.g. piston pins and rings, pump components, etc. Hardness: ≤60 GPa Young’s modulus: ≤600 GPa Coefficient of friction: 0.1 (dry); < 0.05 (lubricated) Thermal stability: 400°C (air); 650°C (vacuum) The cylinder bores can also get WPC Treatment.

Very impressive. But how does the thinner ring hold up under say, road race conditions? How many miles will this ring go before it needs to be replaced?

[@peraz968]

Hi. Just whatcing your videos and this came to my mind. I thin you should test RVS oil additive. Or actually it is not regular additive, because it works pretty well after it has done it's job, even if an engine oil is chanced. One Finnish TV program tested it years ago, and wanted to see if it really does anything. And it did. They drive like an 100 miles completely without any engine oil. And engine did handle that almost like nothing. Of course it was hot like hell, because there was not oil to lubricate and transfer heat. But all bearings, pistons etc. all worked just fine without seezig! It would be interesting to know what kind of power difference this product can make. Thanks for the videos!

[@markdixon4912]

So lake what kind of difference do you think you would see with a sumebore over the rottler bore?Also would the thinner rings work with mild amount of nitrous assuming you gapped them correctly?

[@russellweber3466]

In most cases you get what you pay for with quality components.

[@ICONBADGTA]

I had a set of Probe FPS series SBC pistons in 2006ish-2008ish that had the horizontal drilled gas ports with 1/16-1/16-3/16 ring pack... I'd like to see a true "APPLES TO APPLES" comparison of the (SAME EXACT SIZE) ring, for (BOTH) just one ported and one not... Not different sized rings... I think the ultimate gain wouldn't be anymore than 10HP at most, and what about "BLOW-BY"?!? Less tension generally means more blow-by and possible oil getting past into the chambers to get burnt... Ram has a recall on certain engines made by Fiat/Chrysler due to low tension rings causing oil consumption issues. And what about Boost?!? For instance a super-turbocharged 10psi street engine.... I rather have a little bit thicker ring for durability.... Less prone to breakage by accidental detonation, etc. Thoughts?

[@CherezianRacing]

Great results. Question i have is was the hone the same for both the A and B test? If so was the block rehoned to the same specs after the A test?

[@INFANTRY1981]

I think we can safely (assume) for the gas ring test, the cylinders were inspected and wiped clean. It could be argued that the non-gas ring test was used as a pre-break in but they admit as much anyway as they explained "manipiulated" data - EXTRAPOLATED for water/oil temp diffs. In the end, I though it was a good test, obviously targeted to the race engine builder and not the garage scientist 'assembler' like myself. Then again, I know if I want to run a modern piston in a 500-600hp BB build, I prolly need to get researched on gas ported ring - piston matches.

[@CherezianRacing]

@@INFANTRY1981 really dont want to have to assume anything when dyno testing haha. If it was rehoned to the same specs the "A" rings saw then it would be a great test. If they were just "wiped clean" then its not a fair test as im sure the cylinders had different readings after being broken in with the "A" test.

[@reallivehumandrummer4438]

What is the part number of the 1/16, 1/16, 3/16 Hasting rings tested first?

[@MrGivmedew]

I have a very important question. On the engines I build for my cars I usually use rods that really can’t handle a significant increase in power. So like on a 2 liter of the stock rods 300HP the new rods can only handle maybe 400HP. So I have to be mindful to not exceed what the rod can handle. So my question is this. Does the extra power you are making exert itself on the rods? Meaning that the rods on the total seal setup are experiencing more force on them than the other rings. I assume yes but just want to know for sure. Thanks guys, been using your pistons since the 2000s.

[@427_FE]

Did you test the 1/16 gas port rings on the same pistons that had the ductile molly rings? That would be an interesting comparison for those that don't want to buy new pistons.

[@turbotrana]

Instead of thinner rings, why not step the outer edge to whatever thickness you want. I remember using stepped rings in rering only jobs to clear the wear ridge. It was something done 30+ years ago. You would have room for a decent size ring port also.

[@dannyfasttcars8612]

Where do you get stepped rings? Really haven't seen any available

Cost should not be a factor or have any relevance. Inflation and price fixing have made the cost skyrocket. I'm sure the cost years ago was a better value.

[@rolandtamaccio3285]

The hot oil is not all about the increased friction . The point .9 ring combo obviously had less blowby , especially near peak power . And you know you didn't measure ( or comment on ) blowby intentionally for this test .

Where can we find or how do we know our machine shop gave us a plateau finish

[@kentegel8975]

Just curious ----- What was the difference in blowby between the 2 different ring sets?

[@mightyfinejonboy]

i see videos about ring gap, but what is the gap from the ring side to the piston ring land? what sort of profile does the ring have as in flat or slightly curved face to the cylinder wall. do any piston rings have groves in the face to create a labyrinth seal and can this sort of "seal" be tried on a piston surface?

[@chrispompano]

I wonder if these rings could help a Delorean outrun being chased by Libyain's & get up to 88mph faster! 😂. The poor Delorean's 130hp PRV V6 is so anemic & could use so much help from modern day American technology, & is my dream of what can be done to that motor with an American race engine builder. The PRV V6 was Europes sbc developed jointly between Peugeot Renuault & Volvo. However the 900hp race engine won LeMan. Now that's a dyno test I'd pay good money to see!🏁

[@75west]

verbal description of rings 3/16, 3/16 is confusing. better to describe them as iron versus steel rings.

[@69Applekrate]

Nice, informative. Less wear, less heat, less friction, more HP, etc. What about mileage tests? I'd guess most of your customers are street apps.

[@69Applekrate]

@PurpleNovember it would seem that it would but, do not know from experience

[@joecarroll1735]

[@JamesCopeland-i1j]

18:54 "you can buy a cam shaft that will..." No you can't. If that cam makes more power EVERYWHERE, like these rings, that requires a higher energy lobe. High energy lobes mean shorter service intervals. These rings, with the proper hone, will EXTEND your service interval... in more ways than one.

[@dangerousfreedom4965]

Thin rings are great for race applications but not on the street

[@byronneal8638]

So, would it be safe to say that the gas ported rings contract during the intake stroke due to the vacuum in the cylinder? Further reducing friction and wear. I have always wanted to see just such a comparison as you have presented today. This is very interesting for an old school engine guy like myself.

The differences what is are you doing a cheap ring or you build a full race motor that's the answer. I always use the cheap set of Hastings ring rerings are you building a street engine that want to get 300,000 out of it, all right all out race engine.

[@dannyfasttcars8612]

How would less wear on the rings be a race only situation? Less friction n wear is just as beneficial for any moderate street engine. Junkyard engine with rings thrown in for under 300$ is a whole other story

Well I'd really wanna go with a gas ported top and a gapless second ring. But i don't know if i can justify spending more than half of the price of my pistons on rings And especially the customs fees, taxes and shipping to get them sent to Germany

Gotta pay for HARTFORDS pro stock bills somehow!!

[@thereckchanic4709]

Will it last 200K miles though with the carbon buildup inside the pistons on a daily driver?

[@shanerorko8076]

18hp for $400 it's not too bad, but the lower temps is going to better.

[@icetech6]

Ugh.. one more thing to stress about... I need someone that knows this shit to build me a 408 mopar shortblock :)

[@patbeattie1989]

Did they mention a %difference for the HP number?

[@jessesyfie7244]

You guys dont show your rpms on your testing of these rings? Why so. I almost bet your 18hp more increase gain on these expensive rings is at the top end, 5000/6000 rpms. I almost bet at 2000/2500 rpms where a street engines spends 90% of its times they dont gain anything there or very little. These would maybe justify for a race car but for a low rpm towing and pulling engine a $200 set of rings veres a $600 rings doesnt justify. I dont even use $200 rings I still use the 5/64/5/64 3/16 rings packadges in all my engines cause most of my engines are stock bore size and I only bore them enough to clean up the wear and .020 over is what I use alot. Theres not as many rings choices in .020 over sizes. It doesnt pay to put expensive parts in low rpm high torque engines and pulling for mileage cause u cant increase power much under 3000 rpms on a gas engine, just the way it works.

100%! Let's face it: below 5252, its all about the torque. Let's say below 2/3rds of the magic [and arbitrary] number...

[@MVPisME383]

$600 for the rings, how much for the pistons that run these rings

[@loicdore39]

Why did you just groove the pistons to the thicker rings ? Simple job
