Over 1,000 HP... It's one of the BEST Back-to-Back tests we've done! 

Now, finding a good machine shop is the challenge. Components are more reliable and available, but talented people with modern technology is not abundant.

This is anecdotal but fits this video. We were a budget nitro funny car in the late 90's into the 2000's. Oil dilution was a major concern. Warm up oil would come out a very milky, light butterscotch color and was a throw away item. We were constantly looking for ways to cut costs and after a night of bench racing and being informed that there would be a new piston and ring order being made shortly, I decided to call Total Seal to see what they had and what the pricing was. I handed the pricing and info to the car owner, he was skeptical, the next time I saw him and the decision was made. At our first race with the TotalSeal rings the warm up oil would come out a very dark butterscotch and could be reused for a second warm up. The oil savings more than made up for the cost of the rings. Sometimes there are reasons other than horsepower that get you to try something new.

Early 90' US used gapless Total Seal rings on HD motorcycle engines. Great results, no boring cylinders or top end reworking

Awesome to see more diesel content! The BMW M57 needs some gapless ring love. They have a lot of blow by.

Probably one of the best back to backs for rings I’ve seen and to impress him I’m sure isn’t a easy task. Awesome video 🤜🤛

Good back to back comparison. Thanks for sharing 👍

So glad I found this channel

I love Lake. I coudl listen to him all day just to learn as much as possible about his knowledge on Both Rings and Tribology.

Stock 6.7 cummins are really beefy units. A stock block and crank have been north of 3000whp. They dont really last but they can make the number. The one thing i havent figured out is why an OEM hasnt used gapless rings. You would think with tightening restrictions on emmisions and efficiency, getting 1% power for almost no R&D and a drop in blow by it would be a no brainer.

Now they need to re hone the bore and see if they can get more

Beautiful guys. Love Your Rings.

Of course Lake is going to analyze the oil. He gets to wear his lab coat, pocket protector and big 👓

Great info! Lots of naysayers implying the CGI Cummins was weak were just proved wrong.

Ill be using gapless on my next engine build!

Good stuff 🎉

I wish gapless rings were standard in all engines. Everything seems to be better with them. My 355’s oil stayed cleaner much longer with gapless rings and oil consumption was unmeasurable.

Good video.

Great video thanks for sharing.

gapless is def the way to go

How about including the speed of air dimpled thermal coated pistons, poly quad valve modification, super porting the heads and applying thermal barrier/dispersant coatings?

I saw a video (Extreme DIY) where he put magnets on his oil filter and when he pulled it apart you could see the metal stuck on it

Id like to see project farm due his oil bearing test on each oil gapless and normal gap ring to see the wear difference

While this data and information is great. I'd love to see long term testing. Gas and Diesel. I chose not to use gapless rings on a few of my daily drivers as I couldn't find any non racers that had used them more than 20k miles. Even a few people that said they needed to rebuild again 50k miles later.

I've read that turbo engines (gasoline) need a bigger second ring gap to prevent ring flutter.. but I'm guessing there's no issues with the gapless ring. The top ring is probably sitting there thinking " there's no point in me being here" 😂

Hey, could you guys cover the use of upper cylinder lubricants like Lucas ucl or equivalent? Like is it helpful, hurtful, or a waste of money? I’ve always seen both sides while researching but of course, it’s always just another opinion, never science or data. Thanks for all you guys do, new sub from me!

Great video! What ring gap (gapless rings) do you recommend for NA and boosted applications? Thank you!

Very interesting.

Next they need to swap in some dimpled pistons.

The engine came up faster and smoother with the gapless rings.

Has Total Seal or anyone else done a comparison test of a custom piston set that used a rectangular top ring instead of a Keystone, and then made the top rings gap less instead of the second . Even on a turbo engine I would think that would be better than a gap less second. Not all diesels use Keystone top rings, VW doesn't, I don't know about Mercedes or BMW car diesels. Audi is a division of VW and they won the 24 Hours of Le Mon a bunch of times with a diesel car. Maybe the engine had a keystone top ring, but since it was a VW engine , maybe not. Perkins had a 5 ring piston on at least 1 of their engines back in the 60's, the third groove had 3 thin cupped rings in that third groove, 2 facing toward the single ring that was cupped against the pair. So gap less is nothing new. Today with thin steel rings being more common , it wouldn't be that hard to stack 2 rings in the same top groove. And why do hard pulling engines have a problem with the top ring sticking anyway? Isn't that caused by EGR and closed crankcase venting? Case IH does all of their emission control in the exhaust , no pathetic EGR. Problem solved!

I need mack e6 size rings! Wanna rebuild a couple of motors

Was there a different oil used in the gapless ring runs? The results sheet shows quite a difference in the additives.

Great test.I wonder what the longevity of the hapless ring is like? Will it last 500 thousand km like a conventional ring in a daily driver?? I’m wondering if it would go well in my Toyota 12HT that I’m building?

This is going to give Subaru Fanboys PTSD

What about doing a test on the golf ball pistons!

With a back to back test… them standard rings in all reality should have 1500 miles on them to really seat the cylinder well… was that the case in this test? Back to back the total seal ring design should seal better IF the OEM rings don’t have proper running time to seal?

Would a gapless 2nd ring be a bad idea on a high reving gas engine due to trapping gasses between the rings? Would a gapless top ring work better in that case? Why doesn't every engine use gapless rings?

And we wanna rebuild detroit diesel old 2-strokes tooo🎉 bigger rings please

Why is it you guys used the gapless as second ring? We got it as Top Ring. Thanks!

I would like to see what you could say about DeltaHawk DHK235 engine. 2Stoke Diesel, 2700rpm, 235HP, 202cu/3.3l, V4, 90degree, 474 ft-lbf/642 Nm

Real #SCIENCE not #Speculation !! Busting Bro Science Daily 💪💪💪💪💪

Honestly, id get a set if they weren't so expensive (or available for my miata motor)

Lake, what were the honing specs in this engine? Did they go aggressive on the valleys like you’ve done recently? What about their cross hatch angle?

How bout speed of air pistons?

Interesting! Why gapless 2nd ring instead of top ring?

How do they solve the expansion of the rings, surely the rings will gall and seize, I understand the stepped ring concept but a solid circle ring??????

Data, it's evolutionary voltage.

Does total seal have gapless diesel rings for the VW 2.0L?

Id say Gal banks is the guy TBH

whats old is new again it seems, quite a few engines before ww2 had rings just like that

Well you didn’t look hard f diesel mate ford falcon 3.998liter straight 6 just add more boost nothing else easy HP

Please stop playing music over the dyno runs, what’s the point

I would probably give credit to Gale Banks as the best Diesel builder in the country. Wagler a close second.

Thank you for your knowledge and videos USA 🇺🇸 TRUMP

Get rid of that stupid music..🤡🌎🥴🥴🥴
