Ceramic coating turbo

[Super Bleeder!!]

Why wouldnt you coat the inside? If the inside was coated the heat would have less of a chance of being dumped into the turbine housing metal.

All coating the outside of the housing will do is make sure the turbine housing cant radiate heat into the engine bay, because most of the heat will be trapped inside the material.

imho, from a logical standpoint if you are going to coat it at all coat the inside.

input from others welcome.

Its best to leave anything out of the intake tract. EOS.

Swifty, where was yours done?

Turbine Housing = exhaust not intake

As Floppy said, if all you coat is the outside, you are trapping all that heat in the metal, and not leaving it a nice escape route do to the ceramic coating on it. Coating it inside as well, will give you a barrier helping to prevent some of that heat from ever even entering the metal. Go read up on a lot of the coating forums, and you'll see a majority of them are going to recommend coating both inside and outside.

I also had mine done by Bob at Form and Function. As others have said, he works out of MAP's shop now which is nice and convenient. I had both my manifold, and my turbine housing coated with his Black TurboX coating, inside and out. I definately recommend him.

If you do a search on here for "Ceramic Coating", you'll probably run into the thread I started about a year ago on it. You'll see my pictures in there.

I was quoting super bleeder and missed it said turbine housing.

Regardless, you got a ton of heat and pressure depending on your boost levels so I would have to say not a good idea. Anything in the intake tract or the exhaust tract that has has an opportunity to become free is not a good idea to have. Besides if the outside of the turbo is coated, there is no use of coating the inside, wheres the heat gonna go besides through the exhaust turbine!

There is a use for coating the inside. Like what was said before, When you coat the outside then the heat get into the metal but has to good way of releasing the heat. Whereas if you coat the inside then the heat never gets a chance to see the metal it would just flow right on though and out the exhaust.
As far as it flacking off. What, is a tiny flake of ceramic coat going to mess up your turbine wheel? Probably not. And as what was said before, If it flakes off then it was a crappy ceramic coat/job in the first place and probably didnt do much for you anyways.
