Piston Coatings
Does anyone have any experience with coatings used on pistons? I've seen coatings for piston skirts, piston tops, etc. Do these work or is it a waste of $$$?
Thanks

Hi Justin:
In a turbocharged engine that is subjected to a great deal of heat stress, these coatings do work to reduce the thermal loads imposed on the pistons.
As you can well imagine, these must really be applied properly to do any good and stay in place at 1600 deg F.
A Thermal Barrier on the piston crowns and the Anti-Friction coating on the skirts reduces oil temperatures and chances of piston scuffing when the P/C's are new.

Justin;
I have enclosed a picture my original 98mm Mahle piston designed for a 964 stroker motor, and my new set of JE's. I have used and seen coatings for many years now, but last year I decided to find out the various commercial manufactures of the coating and to try it for myself. It is a very easy process (these were not my first attempt). I would recommend this to anyone that want to push the limit, besides the OEM manufactures are doing it. One of the reasons that I coated my pistons was to reduce the piston scuff, you can see the bright polished Mahle skirt. Reducing heat transfer in high boost situation will save our engines.
