Ceramic Coating

[cnichols]

Obviously it would be a good idea to ceramic coat the turbine housing, the exhaust manifold, and downpipe, but I never hear of too many people ceramic coating pistons or valves...is this just overkill unless you're using Nitrous?

Any other places that are recommended to get this treatment?

Ceramic coating is done to reduce the heat that said part is letting out, and also because it looks cool. It also takes longer for it to rust, but eventually it will.

You wouldnt want to ceramic coat internals, for a couple of reasons...

1. Ceramic coating would increase the parts size, ie piston bore and height, as well as intake or exhaust valves. This in turn would also increase the parts weight.

2. It would produce more friction should you coat a piston. Pistons (good ones, at least) have a coating on the pistons called molybdenum (sp) that reduces friction, and covering that should be a sin, if it isnt already.

3. For the reciprocating parts (pistons), coating them would probably through off balance, and you would have to go about re-balancing them.

Thats how I see it, if Im wrong on anything someone please correct me. Hope that helps.

What about coating the exhaust portion of the head to decrease heat absorption by the head itself and therefore increase air flow velocity?

Im not sure about that...Ive never heard of it being done before, but that doesnt mean its impossibe.

Heh, thats exactly what I told him Drift. : ) Apparently Corky Bell Suggests it in Maximum Boost, but my lazy *** still hasn't looked at it.
