Coating piston tops with a ceramic coating

I have a quick question for those that are coating piston domes. Any thoughts or trials on if coating would help prevent ring locator pins from backing out? To my understanding one of the biggest contributors to them backing out is because of the heat cycles?

Check your PM for the answer to your question.

FMP, have you used them? I see they are up north by you. I did appreciate their info given about the gains in torque and hp. I think its a good indicator for the coatings and what they can do. I am not saying they are all the same. But what I am saying is that they all should be similar. Some will be better than others. But if they didnt do their job, the coatings and coaters wouldnt be in business right? That statement is made by comparing apples to apples......piston top coating to piston top coating, nothing off base or weird. Some coatings may have larger gains or be tougher or even more flexible...I dunno. But to be an exhaust coating or a piston coating, they must have similarities or they wouldnt work in their respective environment...........like coating a top with DFL. What I am trying to say is this.........if the coating is decent(some being better) it will bring power levels up and protect the engine all at the same time. Where's the loss there?

I really am going to coat all my exhaust parts, domes, and combustion chambers on all my personal outboard builds from now on. I think its foolish not to........when you can gain measureable power just by "painting" your parts or having a pro "paint" your parts for you? Those are loose quotes by the way.........its more involved than that

Been using them for years, very good company and quality workmanship. They coat my stuff ( I don't do pistons tops, as it creates other issues)

I coated these heads with aluminum a while back ...



Made em where they would fit .



I'm digging them out of the mothballs and going to use them on the "stock 225's " I'm hangin together ... after I make the chambers look like this ...



Next pair .. slugs will look like this ...



You guys outside of "the world" are pretty limited I guess. I'd ask thunderfire or whoever they are if they import TechLine products ... Wheel's look good .. just like DiamonDyze ..

Hey Chazz..watching the vidio ….. can we just use this new stuff instead of nick/chrome? The more you polish the shinneyer it gets?

Seems like thats the 1st thing people do is piston tops can u tell me the other issues it causes? Not doubting you but im bout get some coating done also and would like to know of people different experiences I havent heard about any cons yet thanks.

Curious too...........

But I am still coating mine......

[powerabout]

Imho and no testing done, i think you get 2 issues.
More heat resistant piston so more safety margin.
Less heat lost into the piston so hotter chamber so should increase bmep and maybe detonation if your close with the fuel you use?
But do you now need a modified cooling system and modifed tune to suit the fuel you use?

Here's a question.....can the ceramic coating be used to fill imperfections in a head........like minor pitting? Like could you spray a coat, bake it on, rough up the surface again, and apply another coat? Just me thinking outside of the box.

Anybody ever tried it............kinda like using it like bondo.........apply coating, sand it down, pits are now filled in, apply final coating, new combustion chamber...yes? no? maybe so?

Whatcha think Mr Chaz? And no smart#@$ answers either!!

[Chaz]

Pits ... like pores in a sand or foam casting ... ?

Or Pits ... like in when ya peel back a piston crown and the shrapnel from the ring embeds itself into the head ... ?

When all else fails , read the instructions ...

One thin coat , bake and serve ..

Bondo is in Isle seven next to the putty knifes ..

This stuff works pretty good , in filling those pesky trench's ...

Apologies for the hi-Jack, but since there’s some smart guys on here talking about thermal barrier coatings, I wanted to ask if there is any advantage in ceramic coating the tuner for a high rpm motor? I’ve already done mine, more for looks, tbh. I’m not so dumb to think it will be any discernible difference in HP output, but it should have sort of the same effect as keeping cooling water off the tuner, no?
Not to mention helping to protect the tuner from corrosion (since I’ll be running in salt water):

[keefallan]

It was previously posted that you can expect gains with the tuner coated. It may have been taken down. The answer is yes...there is gains there. But You should try and coat the rest of the exhaust tract as well........keeps the speed of the exhaust up.......improve scavenging.....make that tuner work even better.

1) pits from detonation but no ring plinko..........call it somewheres in between your statements

2)Why read the instructions when I can just ask you? Of course I'd read dem structions......but sumtimz.....I'z trying to tink outside der box... ever done dat one.....?

3) Your are able to get enough heat into the surrounding aluminum to ad that solder sticks? I have no problem using them as filler, especially if I am gonna be coating on top of it. But my biggest prob is getting 'nuff heat .
