Does anyone have ceramic coating on their pistons or heads? I have heard that you can gain alot of horsepower from having this done but that it is rather expensive. It seems to be a good idea but I want to know more. Any knowledge shared is greatly appreciated.

 

never head of ceramic coating on the piston or heads but i have the silycone coating on my speedpro pistons. it allows for better heat dissapation and less friction.

 

Ceramic coating on the pistons is supposed to hold more heat in the combustion chamber which results in higher temps and more pressure on the piston during the power stroke.

It also provides some protection for the piston against detonation. Try also:

The site doesn't get into the ceramics, but I know they do this for some big names.

I believe this is a good product, but only cost-effective for race applications, severe-duty, or forced-induction.

 

Thanks for all the info.

 

you have three types of coatings on an engine....

piston crowns, valves, intake ports, bottom of intakes, headers are usually coated with thermal barrier coating which limits the bleeding of thermal energy through a surface.....

Coating the piston crown will trap more thermal energy thus having a positive effect on the force acting on the iston during the powerstroke....

coating the valves also aids in keeping the thermal energy inside the chamber thus reducing predetonation on forced induction engines...

Piston skirts, bearings, oil pumps, valve stems, all recieve a dry film moly lube coating, this coating aids in reduction in friction....once wet with oil it allows all moving parts to slide with ease, less friction=less heat more power

heat dispersant coatings, water jackets, blocks, heads, intakes, oil coolers, radiators, oil pans, tranny housings, etc get coated with this stuff.....it dissapates heat faster than aluminum.....thus allowing for cooler running during severe use....or normal running in severe conditions.

I have afew of these coatings done to my engine and the results were nice.....the Volumetric efficiency of this engine definitely went up...

it is pricey though...

Bruce at Microcoat does some good work

And ya got yer oil-shedding polymer coatin fer that ole parasitic drag on da crank...

 

rom what I have seen, the oil shedding coating is water based...and it repels oil like nobody's business

The lower side of the intakes are also coated with this....in order to keep hot oil off the metal.....

I also had the cyl head valve galley coated with this....in order to get the oil back to the sump faster.....

Valve springs also get coated wih moly lube coating in order to prevent galling and binding for high lift cams....

There are also three types of thermal barrier coating....the silver stuff called cerama chrome, the black stuff is high temp....and they also have a titanium
thermal barrier coating out there. all three are good....and all have their specific uses.
