May intake valves naman ang engine that open and close, actually its a 4 cycle cumbustion process I think, that will control the flow of air. I think what you are referring to is yung malulunod sa hangin, hindi naman siguro. para malunod sa hangin ang engine you'll need to upgrade your turbo and retain the original setting for the fuel supply. But very rare yata mangyari yun, over supply ng fuel yun lang ang nagawa ko... hehehe
