Ceramic coated pistons...

[thefalls]

what difference does it really make to coat forged pistons?
Do they accept more boost?
Does it increase the life of the pistons?
Kindly explain.
Thanks.

"Ceramic Coating, is recommend for use on parts that are exposed to extremely high temperatures such as headers or exhaust pipes, often referred to as exhaust coating, header coating or high heat coating. Ceramic coatings increase part longevity, reduces friction, produces more usable power and protects parts from thermal fatigue."

Found this!

I think on pistons the thing to use is friction reduction coatings, these work by reducing the friction caused by the movement of the pistons which would lead to several things including a loss of power, also extra wear and extra heat building up.
(not much mind I believe). google these cos there's a fair bit of info on friction reduction coatings on the net.... mostly american though when I googled them myself.

you can also get thermal coatings, these do a similar job as ceramic coated manifolds i believe as the thermal coating can either dissipate the heat qucker then the metal or else control the heat within the combustion chamber in general.

I would have thought on a piston it has nothing to do with friction, as the only bit really affected by friction is the piston ring. This probably has more to do with heat spots. Probably not worth it unless you really wishing to push the limits.
