is ceramic coating of pistons worth the effort?
what about doing only the piston tops and not the combustion chamber? I am getting a new set of pistons and can have them supplied with the ceramic coating... I would have to clean up and send out the heads to have them done..looking for forum wisdom. |

I would do valve heads, piston tops, and the exhaust. The idea is to get the heat out of the head. The 951 used alucil to slave the piston, but they didn't use a thermal coating on the block. With the cylinder head of the 951 having ceramic liners it did increased the efficiency of the turbo, but did remove heat from the head also.

QUOTE(Mikey914 @ Dec 24 2019, 06:48 PM)  I would do valve heads, piston tops, and the exhaust. I've found ceramic and DFL don't adhere well to steel, they get a better bite into aluminum. Even with aluminum the ceramic doesn't like sharp corners like valve recesses etc. On my 3.0 I used DFL on the skirts and bearings, I DFL coated my rocker pads, most of it wore off, but you can still see a bit in the "pores". The ceramic coating I used on the piston tops and the head chambers and ports, it took me several tries till I got the process down pat. BTW it isn't the same stuff as on ceramic headers, it's a very dull finish. |
