intake valve coating
Just out of curiosity, did you always coat both front and back faces of the intake valve on these valve coating tests?
I am thinking you might get best of both worlds by coating the chamber face only but leaving the manifold face clean so it is easily cooled by the fuel, Which would also help evaporate and slightly preheat the fuel so it would more readily evaporate as it entered the lower pressure area inside the chamber on the intake stroke.
