I would think it would be bad as you are keeping hot gases inside the exhaust and turbo where you would rather bleed some heat in to the engine compartment. Just a thought though.

The hotter the manifold/header is, the best it will perform. You will improve the turbo lag and protect other engine components.

You'll always have the heat transfer from the exhaust side of the turbine. That's why the inter-cooler is there. I've seen the turbo orange red after drag runs... very cool stuff.

The physics behind it is: The hotter the gas is, the faster it will flow. Hotter gases have more energy.

Edit: I should have stated that ceramic coating will prolong the life of the manifold/header. The turbo and manifold/header "wrap" will help keep them hotter and protect the other engine components.

I have used "Jet Hot" coatings on Tubular exhaust manifolds . It's a nice finish inside and out and it will prevent corrosion and to some extent depending on the manifold lower the resistance of the exhaust gasses (freer flow)

Just be sure to drill and tap it for your pyrometer probe prior to getting it coated. Otherwise there's no down-side but you might want to get it checked for cracks before you go ahead, I'm not sure what a magnaflux scan costs but it'd be a shame to coat a manifold that's ready to crack.

I just got the M&D Engineering VNT Turbo kit for the 300tdi and I'm planning to use a local company to apply a ceramic coating to the the new manifold and other parts in order to keep it from rusting and hopefully also lowering engine temp a bit. This company also does it to turbos. Is it safe to apply a ceramic coating to the turbo? I assume it has to be taken apart in order to do this? Has anyone else applied ceramic coating to manifold or exhaust and if so did you notice a difference in under hood temperature?

manifold

2x on the below. I have ceramic coated my headers on the V8 and the cool down nice and fast compared to the rest of the motor. I have not noticed any deterioration in them.
I used to get my 3inch down pipes of the Volvo turbos ceramic coated as well for faster flow.
"Jet Hot" coated is a specific brand of coating. It leaves a chrome like finished.

coatings

I have not used these guys yet, but hoping to do so soon. Was thinking of doing both the Exhaust and Intake manifolds.

I am not sure I would rap a turbo as you do not want to cook the turbo seals (which leads to blow by of oil past the seals) and also the hotter the turbo stays inside it will transfer the heat to the for and aft propellers heating the compressed air going into the intake which you want to keep that air as cool as possible - hence using an intercooler - IMHO. I use Olympic Coating in Escondido, CA and they do mail order parts. They are pretty reasonable. My ceramic coating has held going on 5 years I believe.
