INTAKE RUNNER COATINGS

Two different coatings are used on intake runners depending if they see wet flow or dry flow conditions. The base coating is an insulating thermal barrier that also produces a very smooth finished layer. The main objectives of this coating are to keep the fuel/air charge as cool as possible by minimizing the heat transfer from the engine to the charge producing a denser mixture and to smooth out the port increasing flow. We have seen a two percent improvement in flow on 18 degree Chev Bow Tie heads. We use this coating for dry flow applications and as a base for our fuel dispersion coating. The dispersion coating is used for wet flow applications, its main objective is to prevent fuel from clinging to the walls and floors of the port. Wet flow testing has revealed approximately a 30 percent reduction of fuel on the walls and floor producing a more uniform fuel/air mixture.
