Any benefit in having the hot side of an S5 turbo and the S5 stock T2 exhaust manifold coated with some type of heat rejection coating. It does get very hot under my hood and among other things I still have anti lock brakes and its computer is next to/ over the stock turbo location.
Does anyone have any suggestions as to what type of coating I should give consideration to........or should I even bother with this idea.

It might look good until you bolt it up and run it. Most coatings wont take the heat made by a turbo. Other than looks you wouldnt see any change in anything like heat

Thanks for the input on this. I was afraid of this issue more than any other.

Im not up to date on coating really. Only thing I can think of that MIGHT hold up a little would be powder coating. Even that I doubt would hold up to that sort of heat. Just give it a good cleaning and let it go

Wouldn't powder coating melt? I mean... thats how powder coating works.... they bake it in an oven and it turns the powder into a glaze. I would imagine it would just turn liquid again and burn off.

edit: it also wouldn't do much in the way of heat insulation.... near zero I would imagine

I dont think it will reliquify, just pretty much burn off and turn into flakes

Ceramic coating should help. Alot of the single turbo guys do that. My manifold, turbine snail, and downpipe are all coated with high temp ceramic inside and out. I've got an A-Spec GT500R turbo kit though. Check out my buildup thread for pics. There are a few color options you have for ceramic coatings too. I chose black and I feel it looks great in a black engine bay.

You can heat wrap the downpipe too. You can even ceramic coat it and wrap it.

Will a rattle can ceramic work as well as a professional job? I know Ive seen some that claims something like 1200 degree ceramic coating

My coating is 2000 degree coating I think. I wouldn't use any less.

this should do it. http://www.performancecoatings.com/headercoatings.html

no affiliation with them but i wanted to do my turbo and they are close to me.

Polydyn coating will resist any temp your 13BT can dish out.

I and some friends have used Performance Coatings in the past with great results. Turbo and supercharger applications and never had a problem with the coating.

You're WAAYY off base. Thermal Barrier coatings have come along way since their inception some 10 years ago. There's a coating for every application, but not one for all. I personally have my intake manifold done in Cerma Chrome. easy to clean and still could be touched after a hot run. The Turbine housing and turbo manifold are both done in Cerma Chrome by HyperKote in Orlando FL. the Chrome does loose some shine on really hot parts, but nothing bad. It hasn't flaked, melted, or turned blue. I'm making a new DP so it's not coated . Using a UV pyrometer after a 1/4 mile pull my temps went like this .......DP (uncoated) 633*F Surface temp Turbine housing and manifold (coated) 377*F. To say these things don't work or barrier against heat is simply living in a closet. Not all coatings are the same or do the same job. The quality of the spray process also plays a role. I've had my intake manifold done for 4 years, the rest 2 years, and I have absolutely no problems with it. Next motor I do, I'll add some dry film lubricant coatings to help reduce friction. Powder coating by the way...WILL flake off. Trust me i've wasted money on that route.

and the benefits....your underhood temps aren't baking. By keeping the heat inside the gas, you're retaining the energy...thus better spool.

Ceramic coating's WILL help you out and I do sugest them. If you need some help finding someone to do this let me know and I will help you out.

Question for you stylEmon: Have you ever had them do your rotor faces, housings, and side plates as well?

I'm waiting for bearing press tools to arrive to take just about an entire engine down to them (they're in Houston).

I'm going to have them coat pretty much all the internals except the intake, just wondered if you have experience with the internal engine stuff? I know their exhaust housing, DP, etc. hotside coating is awesome...apparently they can even coat a turbine wheel with good success.
