My newly ceramic coated engine bay parts
 

Thought id share some pix of the parts i just got back from ceramic coating.
The colour is called Tiatanium and is good to 2000 degrees. Parts are also done on the inside to aid in the heat dissapation.

Most guys tend to polish engine parts but im going for a more black and gunmetal combo, looks great and is functional too!

Parts inc are Efini Y pipe, UIM, and rear turbo pipe.

Lookin good. Just keep all the other parts in the engine compartment kinda a dull gray, or black color and it will look slick.

Looks real nice.

That is my goal basically. I have had some paint custom matched to the colour and are going to paint the altenator and TB elbow. Gunmetal piping with black hoses and couplings, should look crisp.

wow i like that alot

Thats hot, dont get me wrong i like polished stuff, but i like the rugged semi-gloss look. Looks more mean IMO.

Too bad i dont got enough money to jet coat all that stuff, so i just bought a powder coating gun for $60 at Harbor freights, it wont be the same but it'll look nice.

Looks good.

FYI adding any type of thermal barrier will not help heat dissapation from the parts, it will decrease the rate of heat energy absorbtion or dissapatation. If the manifold gets hot, it'll stay hot longer, less of the heat energy from the engine compartment will get into the intake air. It won't make a huge difference either way.

According to the company that did this, it helps the UIM etc in not absorbing engine bay heat. It is not a conductor or absorber of heat its a reflector of it.

For instance the downpipe, if ceramic coated yes it will hold the heat in as you say because the heat is on the inside, and the ceramic bounces it back in and doesnt allow it to dissapate out.
So the UIM would normally take the heat and absorb it. There is no hot air running through the UIM so its not trying to get out either. The ceramic will now bounce the heat away from the UIM aiding in keeping the charge running throught the UIM cooler.

So in other words the ceramic is not here to dissapate heat as the UIM doesnt create it to let it out. Just aids in reflecting it so you dont get heat soak as bad.

You mention yourself that "it will decrease the rate of heat energy absorbtion" so how will it not make "a huge difference" in how hot the uIM could get?

So pretty much your agreeing with me;).

In your first post you mentioned dissapation as a reason for getting the coating. I stated the coating does not help with heat dissapation:).

Awesome color of ceramic coating

Where did you have it done?

Thanx Node, it was done at a place here in Canada. Its called High Tech Coatings.

I actually had him darken the colour by 50% because the titanium colour they have was a bit to light for my taste.

Turbojeff, your correct. I did mention dissapation in my original thread when i should have said it aids in preventing heat soak.

I've seen these parts personally, they are sick.

Thanx bro......
Now I just have to get this car together, summers around the corner!

What was the cost if you don't mind sharin'?

I did mine in a Grey Ice 2000 degree coating. looks close to yours. and it looks hot with some polished parts such as a smic and pipes.

Thermal barrier coatings are easy to understand. They don't like for heat to pass through them -- they slow the rate at which heat can move from one side of the coating (say, a manifold) to the other side of the coating (say, the air that surrounds the manifold). Apply that simple rule to any situation in which you may be considering their effects and that should help you figure out what happens. The harder part is figuring out the rate at which heat really flows through the boundary (the manifold / surrounding air boundary, for instance) that you are considering coating, and sometimes which side is really hotter. Heat flows -- the point of coatings and other thermal management techniques is to reduce the amount of heat that will flow from the hot stuff into the stuff you want to keep cool (or the other way around). Always think about flow when you are doing thermal management stuff -- where does heat come from, and what do you want to keep it in or out of?

With the UIM, consider that the heat of the air surrounding the UIM might be hotter than the UIM. And the cool air flow through it is pulling heat out of the UIM from the inside and taking it into the engine. And that is really the goal -- to reduce the intake temps. Keeping the manifold cool for the sake of keeping the manifold cool is pointless -- who cares what temp the manifold is? If you coat the UIM, less heat will flow from the air outside the UIM into the UIM, and then into the air that is flowing through the UIM. You reduce the amount of heat that flows from one place to another.

I had my LIM and UIM coated, too. However, I think two things make it not all that effective. One is that there just isn't a whole lot of heat flowing from the UIM into the air that is quickly rushing though it. So, even if you reduce it by half, the effect isn't very significant. The other issue is that I do think a fair amount of heat flows from the engine block to the LIM and then into the UIM, all through the gasket mating areas. It might even be that more heat flows into the manifolds this way than they absorb from the air that surounds them. The thermal barrier coating traps some heat in the manifolds if that is really the case. Note that "traps in" just means "releases at a slower rate" -- I don't mean that it literally locks the heat up in the manifold, never to escape -- remember, the coatings simply slow the rate at which heat can pass through the surface that you coated. I don't know that more heat comes from the gasket mating areas (and it might be that there isn't one answer to the question -- it could be "sometimes yes, sometimes no"), but it is food for thought.

Looks awesome! I'm not that into chrome polishing and stuff. I was going to do all of mine to black because I just like that color better.

Yes even on the UIM. Doing it on the inside helps a lot more on something like the downpipe. Keeps the heat in and alows it to flow faster.
On the UIM there is no heat to keep in but he does all parts this way, if you read his site it states that all parts are done on both sides. Maybe a waist for the UIM but who knows it may help in being an extra barrier from stopping heat from getting in your UIM.

Parts like the UIM are done with a lighter coat on the inside then the outside beacuse he doesnt want a piece comming off and being sucked into the motor. The coating is very strong and doesnt chip easy but its just a precaution factor.

The way I look at is heat is heat, and the less the better. I have no way of proving if it makes a signifgent difference in temperature of heat soak, but i can only assume its going to work in a possitive way. The cooler the charge entering the car the better, if ceramic coating aids in anyway of keeping it cooler(even a few degrees)the better in my eyes.

We all know how you could fry an egg on the top of your UIM after a few hours on the road, our engine bays are freakin hot! What i would like to do is measure the temp of the metal of my car compared to a stock one, see if the reading is any different. If it ends up being less then its doing something positive, if not then hey it looks good lol. I will make a post one day after i do this test.

For all the parts in the pix was $200.00CDN, thats with my frequent customer discount. prob looking at $250 or so normal.

Interesting color choice. I hope you post pictures when you have them installed.

Unfortunately I think the point Max was trying to emphasize was missed.

The temperature of your motor will not change or could technically go up since you are not transferring heat out of or through those parts as efficiently as you were before. Note the difference is academic only since 99+% of the cooling is via radiator and oil coolers...

As Max said, you may see slightly lower intake temps due to less heat transfer into the intake charge. And if you are able to get air moving at all in your engine bay, the coating will help against baking your wiring and vacuum lines - again, due to slower heat transfer into the surrounding air.
