High Temp Coating the exhaust turbine housing?

[sdstriper]

I am interested to hear opinions on coating the exhaust turbine housing? A high temp coating such as ceramic. If you have had this done or DIY, info and opinions appreciated.

Is it cheap? Ok then. Is it expensive? I'd pass. Put the money somewhere else. If you really wanted to, throw some high temp black on there.

Are you talking ceramic coating the outside or inside? My son had a manifold coated on the inside once. It wasn't that expensive... I'm thinking it was something like $100 for a 4 cyl... don't really know if it helped or not... they say it makes it flow better ... in theory. So perhaps it might be worth doing on the inside of the housing... after it has been ported that is.



I used Krylon high temp stove black (1200 F) on the outside of mine and it didn't last for beans so forget that. Right now it's a "natural rust" color. :-laf

It works great we have been doing this for a long time this is a pic of the one on my truck

this is a pic of the compressor housing and it has thermal dispersant coating on it. this helps in shedding heat about 10 percent better then plane alum. on race cars that run methanol the intake manifold will ice up with the coating.

As far as coatings or for that matter any parts, I am less interested in looks/appearance than I am the overall performance. EGT's and any small flow enhancements would be worth it for the pricing I have seen. Ceramic coating an exhaust housing looks to be approx. $55-75 plus shipping. So the "paints" are not what I am after,the ceramics have my interest as well as other specialty coatings for inside and outside of the housings.



I like to bump the performance minimally and try to maintain mileage, and as always preventitive measures to achieve minimal downtime, that is most important of all.

both of the coatings in the pics are special coatings the coating on the turbine housing is ceramic and the coating on the compressor housing is heat dispersant coating. the ceramic coating works great it will help flow but not a lot gases flow better when hot. we have found that the exhaust will scavenge a bit better with the ceramic coatings. the heat dispersant coating helps a lot in getting rid of unwanted heat. if you want more info i can pm you a phone number of some ont that has a lot of experience with the coatings.
