Hi all,
I'm looking at getting the exhaust housing of my 1.06 35r ceramic coated (properly plasma applied coating, not just the spray on HT paint stuff that some places used) but am slightly nervous due to the grapevine rumours about the life of GT series BB turbos with heat insulation.

How many of you guys have actually got experience of ceramic coated/turbo beanied GT series Garretts? What's the lifespan been like?

Car will be used for fast road/track, anticipate seeing about 1.2 bar on pump fuel (out 99 RON, but I understand it's similar to your 93).

I've searched but not come up with much at all.

Cheers

Ceramic coating will be fine, running a turbine blanket will shorten the life on a purpose built track car.

I agree with Sean. Here is a good alternative to the turbo blanket that will not shorten life and work just as well.

Why does a blanket shorten its life?

Thing is, a decent ceramic coat should, to the best of my knowledge, keep the heat in very well indeed, with results that aren't too far off that of a turbo blanket. I've spoken to people who have been able to touch the hotside within a minute or so of killing the car after a run - that's pretty impressive for a coating - that heat's gotta go somewhere surely, and my concern is for the bearings.
I'm sort of looking for some figures if anyone has got them? As in if you'v had it done, what do you use the car for, how many miles is the turbo on, and what's happened (i.e. nothing, it blew up after x miles, etc etc)

I'm not saying anyone's wrong or anything, I'm just a hugely sceptical person when it comes to, err, everything

The main benefit of ceramic coatings is coating the inside of the turbine housing. Even coated inside and out its still does not work as well as a turbo blanket or shield in terms of heat management.

The best overall solution is a heat shield such as the one linked to above. It keeps heat from radiating too much while allowing the turbine housing to "breath". As for the the OP's original question, ceramic coating wont shorten CHRA or turbine wheel life. I haven't nor have any of my customers experienced it yet.

Swain also has a slick coating for piston side skirts. Would that be useful on rotors or some turbo parts?

Another interesting link from that site about internal coatings...
