arias has two types of coatings. the first coasting is for friction on the skirts. which they are one every pistions that i order. the second coating is for the tops. which it cost good bit more. they say if you melt a pistions with the second coating you had very extreme temps. that coating i make a special order.

schwain tech.

TBC™ Ceramic keeps the heat of combustion where it belongs, in the combustion chamber, limits the heat lost into the bottom end into the cooling system. By keeping the heat in the combustion chamber, the heat will produce a more complete use of the products of combustion, resulting in more power.

TBC™ Ceramic is applied to piston domes by a proprietary metallurgical process that literally co-mingles the substrate for a super high strength bond. This thin, ultra smooth ceramic coating insulates the piston metal so oil contacting the underside will not absorb a high amount of heat. No evidence of oil burn will be found on the underside of Swain Tech coated pistons.

Pistons that do not have the Swain Tech coatings will experience many fuel related problems due to low sulfur fuel and inconsistent additives. The erratic heat from the fuel’s spray pattern leads to heat checking and piston dome melting. Swain’s TBC Ceramic coating eliminates checking and melting.

Hey i dont mind your questions at all, it's those that dont appreciate/listento the answers i give that i would rather not help.

Diesel power, I gotta say that you've got the most skewed, screwed up interpretation of thermodynamics and heat transfer theory I've ever seen. Stingpuller had a legit question and through your smoke and BS, he gave up trying to get a straightforward legitimate answer.

Then, you come up with an arrogant statement like the one above. Puh-Leeeze. Dude, when you get your physics straight, feel free to denigrate at will. Until then, back up your statements with some science, not fluff like "you just don't understand all the stuff I know. "

Until then, we're all here trying to learn a few things. It's like the old saying, "If you can't dazzle 'em with your brilliance......."

Thanks

I wondered if I was the only one. Like I said before I just have a hillbilly degree "i have broke a lot of stuff and learned a little" or aleast I have wasted a lot of money trying. My question was a real question. I really was wanting to know. Thanks Jeff

Well as ignorant, uneducated and skewed my interpretation is, it sure has made a lot of fast trucks and worked well in the field or shall i say the "real world"

Who know's maybe i did not fully understand the questions being asked? most of my replies were based off of the saying" keep it simple stupid"....

Eather way i put out results ---point blank.

I did my best to answer with out writing an essay. Sorry i couldent help.

Maybe with all the extensive knowldge Redbone has he could better address the question/s

You need to take a chill pill. Your not the smartest person in the world. One minute you say peak cyl can occour befor TDC which it can't and then someone calls you on it and you shrug it off. You may have built some fast rides but that doesnt mean you have the correct answers to everything.


No matter how smart someone is they will be wrong at some point. The fact that we have lots of people to give input is what helps to come up with the best ideas. :hug:

This was my responce to his question.

"Well i think that you can have tremendous pressure before TDC, maybe not peak but enough to slow the rotaion up and cause bent/ broke stuff

No shrug off there.... initially i jumped the gun on the answer then i corrected my self. im much better at explaining these things over the phone rather than typing.

There are only a limited number of folk running forged, but so far the results look promising.

A little background, an "expert" had said a couple years ago that he had extensive test data on forged pistons in diesels and said they would not hold up. So folk are a little edgey still. Rumors by "experts" have killed more parts than failures ever have.

the only other option is cast right?

Cast pistons have been cracking on some engines, hence the huge interest in forged.

Here's a dirty little secret that's not so secret. The life expectancy of a built Dmax is still not very good. So if the concern is that forged pistons won't last as long as stock, it's not really relevant yet. We probably won't know the normal lifespan of forged pistons for another year or more.

The oldest one I know of, lasted 3 years, with Ross slugs, then the oil rings stuck. Pistons were still intact.

"Why are we racing our TRUCKS?"......Well cause gassers suck:rofl::joker:

Well said Pat! IMO, were fighting kinda a mute point here, Like Pat has said, "theres no free lunch". Were prolly as close to a "free lunch" as anyone with our high powered diesels but theres prolly always going to be a trade-off, performance or longevity, which is like oil and water, they dont combine well. Some of us are getting away with super tricked out cast pistons and some are seeming to make forged slugs last. still a crap shoot at high HP levels till we see more trucks runnin them. IMO, coatings might be the "free lunch" when used on forged slugs but only time will tell;)

When time comes for my build, so far im itching for forged/coated for mine.;)
