ceramic coated turbo

[saleen01]

I am kind of new to the turbo world but i was wondering since one of the cars i am interested in has the turbo ceramic coated and ive seen a few others listed. i know how the coating helps the exhaust by keeping heat out of the engine compartment but would it help or hurt the turbo. would it retain heat in the turbo and break it down sooner? any info would be greaty appreciated

I really can't see how a coating as thin paint can insulate at all, but a hot turbo is a happy turbo. If exaust gets cooled before the turbo, or in the turbo, it will loose volume and velocity due to cooling and shrinking. And that is what powers a turbo. After the turbo, it is fine to cool.

from what i understand, the ceramic coating doesnt actually cool anything, it holds the heat in, so basically it holds the heat in the exhaust system more effectively, meaning less heat gets transfered to other components

I asked PTE this once whne i bought a housing from them,I was told they dont recommend it as its hard enough to keep the oil seal in tact, the more heat the worse the problem can become, Hence i never tried it.
Maybe Joe can ring in on this

No kidding? I was saying without a coating, you may have more cooling. But then again, I don't see how a thin layer of anything could possibly insulate. I don't care what it is, if it is only a few microns thick, how could it insulate? When I say insulate, I mean keeping heat in.

People wrap turbos with header wrap and the special turbo blankets all the time. My Rivieria T-Type still has the factory coating on the turbine housing. Plenty of turbos have a coating, and no failure. I doubt the coating has that much difference in temp changes of oil seal. The oil seal should have oil right on it to help control the temps.

I think coating a housing is just a cosmetic thing.

that is what was explained to me is it was done for cosmetic reasons but i wasnt sure if it would help or hurt the turbo. i knew it would retain heat in the turbo and also help to keep the engine compartment a little cooler with all the turbo and exhaust coated but wasnt sure about the turbo itself

let us know if you need housings coated....we try to get a bunch together for coating all at once and have 25 or 30 needing done now, most of the GT and std turbos we sell aleready have the housings coated. Avail in Black (JH2000) and the std polished ceramichrome coating. Works well

Oil seal failure due to too much heat in housing? for one the housing will not see much heat increase with the coating, its more of a "looks" thing....The piston ring rides inside the center section and I cant see how a few degrees increase can alter its tolerances much Besides its cooled with engine oil flow through the entire center section and turbine shaft where the ring seals.

Here are some choices

www.jet-hot.com

www.cermakrome.com

www.hpcoatings.com

I am going to use the black coating from www.hpcoatings.com on my GT67 next year.

Also Thermal Tech coatings in Petersburg,VA. They also do a full rainbow of standard powder coating, dry film lube, for piston side skirts, heat reflective ceramic for piston tops, etc.
