Hi-Temp painting for Turbos

[Intercooled T]

Hey Chuck, do you have hi-temp paint for the exhaust side of turbochargers? Picking up a nice turbo this week, want to clean it up a bit :) Still waiting on that downpipe still...so i'll be in touch

It's not really "paint" You would want some sort of Jet-Hot ceramic coating on an housing.

Some powder coaters have "header" powders (that are mostly for looks), but I don't think they are anywhere near the thermal Temps that Jet Hot can stand, and I don't think they are quite as good of an insulator either.

This was just my experience about 1 year ago dealing with another coater and "powder coating" for a thermal barrier.

Bonehead may be able to help you with swaintech or Jethot coatings which I would highly req over a "powder coat" type of coating for a turbo housing. Temps can get as high as 1700F in there, way too hot for almost anything coating related.

VHT makes a paint that actually holds up to the temperatures really well. I painted my turbine housing and O2 housing for my last turbo with it and it survived about 10k miles fine. I'll look for the can in the garage this weekend and let you know the exact model.

I found this on Bonehead's site under powder coating samples: ( http://www.boneheadperformance.com/powdercoating/samples/ )

From what I understood about powder coating, since they have to cure the powder in an oven at roughly 400 degrees F, the coating really isn't meant for anything that gets hotter than that. But I know the pieces above can easily see temps twice that on a normal everyday cruise to work or school and back so I don't know.

Yes, I do carry a high temp powder coat. The colors available are silver, stainless steel, factory gray and black. They are good up to 1000 degrees. I have done many many downpipes, headers, exhaust manifolds, heat shields, o2 housings and turbo housings in this powder. I have not heard any feedback as to whether the coatings have baked off of the items I have done so I am assuming they have not. Now, I can tell you that I coated my heat shield on my DSM about 2-3 years ago and it is now starting to "flake". I have noticed that in most cases that when there is something that is touching the item that is coated, such as a bolt, the rust from the threads of the bolt will start to grow and cause the powder coat to rust also. It is like cancer. Once it starts to grow, there is no stopping it. Most of the items I have done for customers were for show vehicles which were driven on weekends- if that. I drive my DSM everyday which would make the coating less durable from being heated every day. I warranty all of my work I do, but in most cases I cannot warranty high temp powder, if it bakes off over a year or more, due to this. One cure could be to coat the bolt heads also but you still run the risk of having the threads rust which will grow on the part already coated. Items which are brand new typically have to go through a heating cure cycle prior to be powder coated. If it did not and I coated it, as soon as the heat hits the part the coating would peel right off. But to answer your questions, yes I can coat a turbo housing and have done many before.

awesome. thanks
