What say ye?Will there be any clearance issues with ceramic coat on the inside of the turbo turbine housing?The thickness should only add .003 to the housing.Maybe a light port and then coat it?

Just for clarification,I am speaking of the exhaust side.I always mix up the turbine and compressor terms.

 

Port and than coat. Problem is its hard to find a coater that can get it in good enough to stick in high egt pulls. If it starts to flake off you might be saying buy, buy turbo.

 

I'll just do the outside in cermachrome.

 

Jet hot.

 

Doing it myself.It'll be a service I offer, once I get set up and I get comfy doing my own stuff.

 

External coating alone doesn't have much benefit, it will only reduce underhood temperatures. The whole point of coating it to help stop the exhaust from heating up the metal itself. Coating the outside alone will increase cracking since the metal can't dissipate away heat, but internal coating will reduce how much it absorbs in the first place.

 

I may attempt an inside and outside coat.What's the worst thing that can happen,a blown turbo?

 

Like forced induction said, Coating the outside wont have much benefit for spooling or EGTs but the underhood temp is always nice to have low. Ceramic coatings seem to stick better on more porous materials like Aluminum. That is why you can coat a piston top. Coatings have gotten better and if you have a reputable place i bet they could coat the inside and it would last a very long time. Although, unless you coat the exhaust manifold, the heat is still going to soak into the turbine housing all the same, just not quite as fast.
