Hey guys, I just read though CIC's website and according to them getting just about every part of your engine ceramic coated (various coatings) is a great thing to do....

CIC Ceramic Coatings

Ive had a Turbo ceramic coated and engine bay temps were noticably lower so I think its great in that reguard but Im not sure about things like Heads, pistons, valves, cranks etc...

Just wondering if anyone has looked into this much and if it is actually worth doing? or are the benefits barely noticable? (as it is quite expensive)

And im a little sus about getting tops of pistons and combustions chambers coatings as it would stop heat from dissipating from the chamber? They say its a good thing and increases power which I can understand, but isnt too much heat in the chamber also a bad thing?

Anyway yea whats your thoughts

ceramic coating pistons has been around for a while especially if the clearance is too much to bring the right tolerence . heat wise it would keep the metal in the piston less hotter .

dont know about coating valves etc .

It keeps the heat in the mixture and away from the engine itself which is a very good thing. It means the heat is going out the exhaust every time instead of being soaked up by the engine which means it should run better and cooler.

More heat makes more power, the more heat you waist the more power you loose, this is why engines that make more power produce more heat than a stocker.
Are you following me, around 33% of usefull heat spins the crank, the rest is radiated thru the cooling system, around 33% and the rest goes straight out the exhaust.
Alot of engineering power gains have been had thru ceramic engines but cost is a big factor.
In a nut shell if the product you use does what it is intended to do it can only be good, in saying that tho I would think if it was working that good then you would have to consider;
A. clearances would no longer be in spec, ie. standard pistons - coated would now not expand as per OEM,
B. If it did retain that much heat then would detonation be a problem, maybe timing could be tuned to suit.

If you can see where I am going with this I would recommend u stick with OEM coated parts when it comes to pistons etc, I don't see a problem with manifolds etc.

Does the supercharged V6 commondore have ceramic coated pistons?

I was able to inspect a Lycoming 0-360 aircraft engine,4cyl flat 4 360 cubic inch air cooled motor redline 3100rpm that had some ceramic coatings when it had its 2400 hr rebuild.

He did the piston crowns,Combustion chamber in cylinder head,exhaust ports, intake valves on combustion side,exhaust valves on the combustion side and on the back of the exhaust valve.He used swain tech in the USA? and they claim the ceramic coating has a bond strength of 100,000 psi.

The results were pretty good it knocked about 30 degC off the oil temps and the CHT temps are also lower which means he can now go full throttle to cruising altitude of 12,000ft instead of backing off to keep temps under control.
These lycoming engines are notorious for exhaust valve problems which are heat related and the rebuild showed these parts are lasting much longer with the ceramic coatings.

Power wise the gains are very small so not really worth it for that reason yet it works well for improving durability.

the japanese made a ceramic motor. shit you not. the whjole kit was ceramic, temps were down, no parts needed replacing like rings an stuff. it revved out of this world and weighed bugger all. guess who bought it and hushed it up?

4AGZE (toyota) pistons have ceramic coated crowns from factory (as do all replacement pistons)

Hey guys, just digging this thread up from the pile as Ill be building a motor soonish so yea, hopefully can get more opinions.

I see CIC now list that they can coat bearings and cranks, increased lube and protection apparently

Also was thinking of getting the pistons, combustion chambers and valves done, but will be using forged pistons so worried about clearances as the pistons wont get as hot (well they shouldnt if it does what they say it does) so should I have the bores machined abit tighter??

I would do the exhaust port as well stops some heat going into the cooling system.
If you are worried about piston slap aim for the tight end of the piston to bore tolerance.

I doubt that i would coat the bearings if you have good oil pressure that will not be an issue and i doubt the crank coating would do much in shedding oil with something spinning at 3000rpm.
