Heat proof ceramic coating

Franco Cozzo · 04-05-2013, 05:14 PM

Hey guys, I'm after some advice on ceramic coating, I've got a Holset HE351VE turbo coming in the mail, and I'd like to get it ceramic coated, some quick google-fu says the black type is better than the shiny "look at me" one.

What parts of the turbo can you get coated? Just the exhaust housing? Or can I just send them the whole thing and it goes in for a dunk and inside/outside/spinning parts can be coated too?

I'm interested because my coolant overflow bottle is actually right above the turbo on my GMC Sierra, and I'm having the feeling if I start putting out a lot of heat, she's going to melt?

Has anyone had any experience with this stuff?

Thanks much.

Yep good stuff .. I have it on hot and cold sides.. critical areas I would still fabricate a shield though..

Is the new turbo any bigger Damo? Just wondering if it is of any benefit seeing as the setup would have probably been driven much harder on duty than you ever would?

Having said that, if it is just for piece of mind a combo of the coating and shield wouldn't go astray.

How are you going to control Variable Vane ?? If it is ?

The boys over at Diesel Place forums have managed to control it crudely using a spring, its functional but obviously not as good as a car with the function mapped into its ECU.

Yeah its a fair bit bigger, the factory GM8 turbo causes a lot of issues on these engines, its undersized from factory, it works ok to 2000 RPM, give the truck a hill and the box kicks down a gear, it causes massive back pressure on the engine and the turbo pretty much becomes a hair dryer, its out of its efficiency range.

Oh ok on std turbo diesel.. Yes just ceramic coat turbine housing and dump pipe..
Or some fibreglass tape on dump pipe for the first 150mm or so..

I prefer the black too.

my brother gets his extractors coated inside and out, i don`t know if one color is better than the the other, but he usually uses the matt black or grey.
this bloke(andrew) does a lot of hot rod stuff and is very good to talk to if you want get info.

Sorry, I have to ask; why don't you want to hear your turbo?

Why drive around with that noise comming out of it - you know you have it, what do you have to prove.......

Because it will be around the same as this, which is freakin' loud.

You can already hear the factory turbo spooling up loudly inside the cab, even with the windows closed and all the crap in the back rattling around.

The outlet on the exhaust of this new turbo, is 4", so that pretty much means I'm running 4" exhaust from turbo to the tail pipe, so even with mufflers and a cat in there, its probably going to still be on the loud side.

yeah have nothing but good things to say about this bloke, we welded up an item and sent it to get a coating to andrew, after blasting it he found a bit of dodgey weld, he re welded it up and did the coating no fuss no problems, top bloke.

HPC down in Leongatha are a great place, had all my housings and dumps done there. For memory my GT42 exh housing was $80, the finish is still perfect on it, id still run a blanket/beanie on it if you want to protect surrounding areas.
