I can't seem to find a 100% definite answer on this..
Found a local shop to do ceramic coatings and I'm curious to WHAT I should have coated and what not. What I was thinking is the turbine housing outside, inside, wheel, manifold inside and outside.
Yes / No to the above, and why? Thanks!

never heard of coating the wheel.
and the only thing i've seen (unconfirmed / uncorroborated) is that coating the inside of the mani and housing can lead to flake off going through the turbine section.
I think my manifold IS coated on the inside. fwiw.

I've read about some RX-7 club guys use a company called Turblown for coating the areas you suggested.
Some pics of coating said parts here:
http://www.nothingained.com/turblown...s/coatings.htm
Actual website here:
http://www.turblown.net/coat.html
They use Polydyn ceramic exhaust coatings and claim a surface thickness of only 0.0002" - 0.0007", compared to say SwainTech's WhiteLightning which is about 0.015" thick.
I have no definitive answer to your question, but FWIW SwainTech rags on everybody else's coasting as either being just pretty paint and/or too thin to be an effective insulator. They also do exterior only on turbine housings and manifolds claiming its not possible to get good adhesion on interior surfaces. Something about the difficulty of sand blasting interior surfaces at a 90* angle.

Share bitch!
My coating wish list is the same.

I posted on a KC Crotch rocket site asking if anyone knew of a place, and a guy that works for the ford plant forwarded me to his best friend who does ceramic coatings of firearm receivers and such..
http://www.ultracoatingsinc.com/
Then another guy chimed in and suggested this place where he had his intake manifold, headers and some other stuff coated: Powder Coat Plus Llc Excelsior Springs,MO Tel. (816) 863-4420.
Haven't called either yet, been pretty busy

What I found so far from the research I've been doing is that you don't want to coat the inside of the housing due to reasons posted above.
On a turbo car, you want to coat the manifold and exhaust housing with a heat retaining coating, many names for it with various companies, but they all generaly do the same thing. Everyone I talked to claims they are superior, Calico is the only one that I felt was being honest when they said "it's all the same ****, it's all about how you apply it." They are kinda close to me, so I think I'll go with them, and they have been in business for longer than I have been alive.

yes caot autside manifold hotside dp etc good. Caot inside could be good but is dangerous so i recomend you do like i did and just caot the outside of everything hotside and you will be good to go. FWIW powder caoting and ceramic caoting while similar are not the same. If you powder caot your manifold etc that **** is gonna melt off fast. But if you ceramic caot that bitch it will dramatically reduce the radiant, and contact heat to stuff in your engine bay making everything else happier. And trap more heat energy into the hotside making you happier with better spool etc. The shop that did my stuff has since gone out of business i think but they charged me bout 250 $ to do all my turbine mani dp stuff and did great work.

I highly doubt a ceramic coating alone will produce a faster spool on say a GT2554 which is already stupid fast.
Heat retention, yatta yatta, reducing ambient heat output maybe, sure. But as for producing a performance advantage, youre gonna have to sell me because I doubt it.
I guess thats why they use ceramic on the space shuttle.

sad thing is, these showed up in google search with keyword "benefits of ceramic coating" , how do you not find info on google?

Literally 2 lines are from a subaru engineer saying that their ceramic manifolds and downpipes in the impreza help the turbo spool 300 rpm sooner. I think thats a crock of marketing bullshit. Want to make an impreza spool faster?, get rid of the shitty downpipe that looks like a Begi S pipe and turn it into a bell mouth. Not to mention the stupid pre cats.

Thermal barriers lower air intake temperatures which can lead to power improvements of up to 6%.
And once again its all about reducing under hood temperatures.
You know where I think the power benefits are coming from? Reduced intake temperatures.
