Ceramic Coat Piston Tops

[DSM_PWR]

I ordered a set of Wiseco 1400 HD .20 Pistons and I got offered the chance to have the top of the pistons ceramic coated for free..

I've heard little to none info on the pro/cons of doing this and wanted to see if anyone out there has more info...

The ceramic coating is to help the piston from getting too hot.

Ceramic keeps the heat of combustion where it belongs, in the combustion chamber, limits the heat lost into the bottom end of the engine. By keeping the heat in the combustion chamber, the heat will produce a more complete use of the products of combustion, resulting in more power.

Ceramic coating is a thin, ultra smooth ceramic layer that insulates the piston metal so oil contacting the underside will not absorb a high amount of heat. Usually no evidence of oil burn will be found on the underside of Ceramic coated pistons. HEAT is what breaks down oil.

Ah I see, very good

Only bad thing about them that I've hear of is that the Ceramic tends to flake on Daily Drivers and is meant more for Race Engines.. any info on that?

 

[Jeff99GS]

Well I have never heard that. I know they use them a lot in BIG diesel engines with HIGH boost and they last over 500,000 miles. I guess it all depends on how the ceramic is applied.

Diesel exhaust temperatures aren't nearly as hot as the exhaust inside a 4g63. The coating does tend to wear off thus mainly it is used in race engines that are taken apart often that can then get re-coated. If you can get it free why not.

True. But they still use the stuff in diesels for engine Longevity, although it is primarily used in the racing world.

Ceramic coated pistons can be used for 1,000,000 miles in a diesel engine and not once see the heat required to cause it to flake. A gas motor will show that heat daily. Where do the flakes go? We have turbochargers .
