I love this for so many reasons. I think of how many cores would be thrown out because they were already at the maximum overbore. If you had a block at maximum overbore and needed a refresh, you might be able to coat the pistons and hone it round again.

[@HHCHunterYTC]

Frank is the new Teflon Don

[@BoostedSpeedDemon]

that's crazy. I actually ceramic coated my stock Pistons because they had skirt rubbing on them. just did it with DIY ceramic gun coating layed on thicker than usual rehoned the block, put everything back together, and I've put 7K miles over 450 whp on stock pistons and rods from a Mazda f2t, with zero bottom end issues even after a massive head gasket failure, from a 45+ PSI over boost on an hx35w

I love how the same question is asked 8 times , and gets the same answer 8 times 😄 Top notch journalism

[@dazaspc]

Way back in the stone age they used to knurl and machine the skirts to make up for excess clearance. I got a set of old Bedford pistons that has had this process. It also had a baked enamel on them that looked to be polished to size.

[@russbilzing5348]

Yep, knurling held the edge on everything else back then. I knew one fella who tig welded a series of bands about 1/4 inch apart on a couple 413 pistons for a drag racer, then turned them to a wall clearance of about .003" before adding an additional oil ring to the 2nd lowest one. Did quite well but entirely too much work.

[@cars3800]

Yeah my old man used to talk of knurling them back in the day

[@wobblysauce]

@@russbilzing5348 all depends on what you have at hand

[@vin18m]

Awesome info. Only problem is the pistons aren't shiny enough for Instagram.

[@ChristopherHallett]

Heavy duty diesel engine pistons often have teflon coated skirts. I've even seen two piece pistons, with forged steel crowns and ring grooves, and a separate forged aluminium skirt.

[@granthawtree4669]

I wonder how many BYM will try this at home… Another great video boys and time for another BT 👌

[@danielbrealey2924]

Piston coatings is a very interesting subject... Ceramic coatings on piston crowns is another additional interesting coating I'm interested in doing some back to back testing with on my own shit...

[@hillbilly2224]

Great video 👍🤙

[@brockmacckie9905]

Thats interesting awsome video

[@WigglingWaffles]

i read recently about knurling piston skirts and applying molybdenum disulphide to make both the piston and the bore more 'slick' and being nearly wear immune

[@nicholassteel5529]

Cool.!

[@NoDiarrhea007]

With cars it's either: Piston broke or pissed and broke 😉

[@garysgarage.2841]

So is this Teflon or ceramic? And what's the product.

[@johnkraft7461]

Wonder if anyone has ever tried coating the cylinder bores? Like on some alloy blocks that have a sprayed metal coating instead of press-fit iron liners - maybe ceramic could be cheaper ??

[@dirkdiggler9082]

Rings prob wont seat....but ive been thinking of nikasil coating.

[@keananconnor4221]

Yeah right sounds like an investment

[@billyray4272]

Will plastidip do the same thing

[@TURBOTRISTO]

hahahaha

[@ChristopherHallett]

Nah bro you gotta vinyl wrap!

[@adrianzmajla4844]

Nickel Town customs, piston shim assembly tape! You tube search "ichiban moto. How to bore and hone cylinders." This will give you a laugh.

[@CBfilms28]

So this coating is fine for oem pistons too ? Or only forged ?

[@azza9575]

Both

[@cwhaaatt]

To be fair the used coated piston still looks like it was rocking around 😂 guess once that coating wears off you’re in the same boat.. go see sps for some custom pistons true

[@jayoheyo9750]

it will wear off in the tighter areas and remain in the looser areas, so it is indeed working how it should.

[@SloppyMechanics]

Don’t tell me how to live my life

[@johnwilson1794]

I saw Garage 54 do something similar with a can of spray paint. The results weren't quite so good. 😂

[@joelwalmsley7217]

None of their results are very good

[@johnwilson1794]

@@joelwalmsley7217 Yes they are experts at testing stuff we know won't work and proving it doesn't work. 😄

[@gafrers]

03:53 So is it Teflon coating or Ceramic coating?

[@fullboost]

Teflon as the title suggests 👍

[@krispykruzer]

If only there was a coating for the man machine!!

[@stephencordiner1753]

How much does it cost?

[@TheMattzx9]

$55 per piston

[@7071t6]

Basically coat everything which is possible in the moving parts area inside the engine with out compromising any oil holes or parts which require very high tolerances and your engine will last 10 times as long based on OE specs if you changed oil and filters as per OE or even 1/2 the KM's and the engine will last so much longer, but then again what about the gold coating which was done on the Black XB GS which has around 800HP it had black coating on the sides of the pistons and gold coating on the top of the pistons, just imagine how much longer the internals will last if other areas were coated like the crank journals and other moving internals of a engine ? Than Main Issue is COST to do every moving internal parts with the right coatings, which would be in the thousands ?

Frank maybe its time to get a metal printer, that way you can get anything within reason made up by dandy engines etc. :)

[@AdmissionGaming]

What they don't tell you is all the weight your adding to the pistons which decreases performance.

[@needmoreboost6369]

I suppose you build faster cars than frank ?? I think you’re full of it! pull your head in! That’s dandy engines have you got 900kw from a stock port 3L head

[@tthams73]

Teflon starts to deteriorates at 500F and is a piss-poor piston coating! If you want to coat your pistons only use CERAKOTE that withstand temperatures above 1800F.

[@yourmommashouse]

LOOK UP PFAS. Then tell me if you still think you should put Teflon on pistons… which heat up and send particulates into the exhaust which we all breathe and drink.

[@dangoodwin5400]

Exactly. The mind boggles at how the world saw how bad this product is, and yet quickly forgot and carried on making things with it.

[@alternatr]

If the skirts of your pistons end up going past the rings, you have a bigger issue at hand. Tell me more about how you drink your exhaust.

[@yourmommashouse]

@@alternatr It’s ok small brain, just go stand on stand by. We’ll let you know when we need another car crash tested.

[@dangoodwin5400]

@@alternatr that’s not the issue. Well it would of be an issue if that occurred lol, but heat can pass PFOA/PFOS/C8 products through the air and inhaled.

[@karlvanboxel561]

If it’s not a race engine then that stuff will wear off and you’ll b stripping your engine after x amount of kilometres I’ve seen it no benefit really to the street engine builder !

[@philwxwlr481]

Do permanent coatings even exist?

[@TURBOTRISTO]

6th haha great video

[@TheDynamiteGuy]

Seriously!? Since when do you coat a piston to make up for the incompetence that made the decision to finish the bore to the WRONG diameter?

[@Questchaun]

Teflon is bad for the environment I'd prefer seasoned carbon steel.

[@tthams73]

Wait! Is Teflon or Ceramic??? It can’t be both! You said it was teflon at the beginning; then you said it was ceramic at the end! Do even know what you’re talking about???

[@ricusmate]

Isn't teflon a known carcinogen that doesn't ever dissappear and breaks down so small that it's almost everywhere and we are already eating it in our food? Sure, more of that stuff sounds 👍

[@spikespiegel2246]

No, The use of PFOA in the manufacturing of Teflon-coated cookware has been completely stopped. Even when PFOA was used, it posed no harm to your health (if you straight up eat it like your paint chips). Teflon on its own is safe and can't harm you when you ingest it(dunno why you wanna do that). Have a nice day, Karen.
