PolyDyn Coating intake valves and runners? Are there any benefits to coating the intake runners and intake valves with a PolyDyn thermal coating? I have seen a lot of guys do the combustion chamber, exhaust valves, exhaust ports. Not that many do the intake runners as far as I can tell. Is it still beneficial to do them as well?
yes and no....
yes it keeps the air cooler....
no because it makes the port smaller and makes it rough (both cut flow).....
I'm just having my intake V face, C chamber, exhaust V face, exhaust V back, and exhaut port coated and leaving the intake uncoated.
