Ceramic coating questions
 

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.

Share bitch! :) My coating wish list is the same.

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:

Actual website here:

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.

No access to the inside of the turbine and manifold makes sense, I'm not sure how you'd get a sandblasting gun in most areas of those parts. Also totally forgot there were other locals to me here. :bowrofl:

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..

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 :mad:

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 shit, 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 shit 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.

IMHO I think its a waste of time that will produce no visible or measurable results and it seems to be a mostly aesthetic modification.

It has been proven otherwise, do you have some data to back your claim?
Ceramic coatings help quiet a bit, think about efficiency as well.

For example sam i can take my DP after caoting and take a propane torch to it and hold my hand inside right by the spot where the torch is touching it outside and i will not get burned. The ceramic is simply very effeceint at heat blockage man.

Do you have data to prove it does 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.

Quit being ignorant man, there is a boat load of information on ceramic coatings and their effects. There are also several different types of coatings with different properties. Do some searching, or would you like for me to take you by the hand and take you there? :fawk:

------, you offered so heres my hand :jerkit:, take me there. ;)

I spent like 10 min googling and couldnt turn up anything.

Don't have a lot of time, but for starters, read everything you can find on this site

You trying to sound all gansta ghetto? Or are you a racist fuck?

here is more for you, now read it and weep bitch :jerkit:

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

racist

god damn jews

99% of the article is talking about reducing underhood temperatures due to exhaust gas and safegaurding electrical components from heat.

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.

5 lines in this entire article about how keeping the temperature in improves exhaust gas flow. yea, sure, maybe. But has it actually been measured, like on a dyno, you know before and after coating on the same engine with no other modification?

Please link me to the dyno chart, I dont see it.

Woh, these guys actually quoted numbers.
On what engine, do you guys have the dyno chart to prove this statement?

And once again its all about reducing under hood temperatures.

You know where I think the power benefits are coming from? Reduced intake temperatures. :bowrofl:
