I think i have heard of this... Does it keep the heat in the cylinder? That would make sense, reducing the external temperature of the engine through insulation. I don't know if this works in real life though, or whether it is worth forking out the money... probably can be spent else where

I thought it would cost a crap load, hell i'd try anything if it only cost 26 bucks. Let us know how it turns out

HPC & Jethot (among others) do ceramic coatings for various mechanical components.

I say 'various mechanical components' as the coatings were first developed by NASA & the like for the aerospace industry.

You can have pretty much any parts done - valves, piston skirts, sumps, manifolds, etc etc. See http://www.hpcoatings.com for some more info.

is it worth it though?

have a read of the site & then ask the question again [img]/w3timages/icons/smile.gif[/img]

I'm going to get my exhaust manifold done, & probably the pistons & valve heads.

www.zbuild.net has built a L28 turbo and gone nuts on HPC engine coatings. I have read the article on his Z in Zoom magazine a mag we get in Australia very interesting and he's extracting alot of power from that engine. Anyway have a read and if not for the performance side of it consider the extra life from the engine and how good everything looks coated in it.

The whole point of thermal coatings is to not only reduce internal engine temperatures which wear on internals themselves, but also to reduce the overall coeffecient of friction which increases hp and reduces wear also. If you think about it, heat and friction are the number one and two enemies of your engine. The less friction in your engine, the more hp and less wear, while a reduction in heat also reduces wear. Such coatings on the valves will reduce the heat transferred to the intake charge thus upping hp. These same coatings on a pistons will reduce the friction between the piston and the wall itself which keeps clearences tighter for a longer amount of time and adds to the hp also. It is definately a job that a proffesional should complete for you. Their ovens reach baking temperatures which our home ovens are not capable of reaching. These high temps ensure the complete baking and longevity/efficiency of these coatings. Hope this helps. If you are curious, visit www.zbuild.net and check out Simon's HPC coatings which are used on just about every part of his engine.-zbg
