Thread: ceramic coating exhst. manifold- yes/no

To answer your questions, yes, and yes.

Ceramic contains the heat in the gas (less radiating heat to engine bay).
Hot gas moves faster (more energy to turbo)

My very limited understanding is that in order to get the effect of the under bonnet heat reduction you need to insulate coat the turbbo and dump pipe and at least the first section of the exhaust.


I think performance advantage in a landrover is somewhat questionalble as far as realistic performance benifit.

The reall beinfit of coatings, exhaust wraps, heat shields etc is usulally to reduce in cabin heat secondly under bonet temp.

My simple views. If money was not an object then do it otherwise their are better performance options.

Me of even less understanding in this....

- Would it make a significant differance to the 3.9 V-8 ?

Would I gain similar advantages by wrapping the exhaust manifolds in fibreglass insulating tape?

As a relative newby to Range-Rovers, I'm staggered at the amount of heat in the engine-room compared to every other vehicle I've owned or used.

So can you get a DIY ceramic coating paint for manifolds? Rather than paying through the nose for someone else to do it. And are there any alternatives for the diy enthusiast?

James, dont wrap cast iron or stainless steel (or worn / thin carbon steel pipes for that matter) as they will stuff up in sort order.

ceramic is best for them.

wrapping near new carbon steel pipes is fine.

No don't believe the ceramic coating is DYI.

About 20 years ago on my old Range Rover I wrapped a section of new extractor pipe near the starter motor to act as a heat shield. On the way back from WA the pipe literally fell apart, it looked as if it had crystallised.
