Would a high temp paint work on the rear housing on a turbo? They have paint thats upto 1600 degrees but how hot does the housing actually get? Ive seen them white hot in dyno videos but I dont kno what temp that is. In a few years when the turbo needs rebuilding I am going to have it ceramic coated but I would like to do something in the mean time. Would the high temp paint work?

 

No i don't think it would. You can have them jet hot coated but i am pretty sure any "high temp" paint would certainly burn off. Try painting a peice of metal then throw it in a fire for a few hours. If the paint stays on then you good to go huh.

 

your turbo gets about 1800 degrees under hard boost.

 

Yeah, when you deal with those temperatures, the 200F air outside + 1800F temps inside means the paint is gonna have trouble. The thermal stresses it would experience are off the charts.

I mean, look at the alloy steel cast turbo housings - that stuff is really hard to corrode but when you get it at 1800F it turns yukky in a hurry. Even if the paint could adhere to it, the metal underneath would oxidize so it flakes off.

 

Just cover it with a chrome heat shield, nice and bling and keep the heat in.

 

Jet hot is the way to go

 

What are the advantages of coating the exhaust housing of the turbo? That means disassembly is required right?

 

right! check out jethotcoatings.com

 

you could always just try to paint it and see if it holds up

 

Jet hot or hpc would be good I have mine coated hoc did the coating ....the thing is, high temp paint is still paint, this will burn at sustained temp over 800f. ceramic matrix is what hpc and jet hot use this will burn at 1300f is sustained for a long period as well but we are talking like days of constant heat

 

Regular ceramic glazes are fired at about 1900 deg F. Maybe you could decorate it like your favorite coffee mug!

 

thats great. lol
