Stop in for a cup of coffee

Yeah, warm for my likings anyway. 210ish at freeway speeds. I have electric fans and with the hood on it actually runs cooler with the fans on. With the hood off 190 all day long. So I’m going to open up the fan shroud where I can and put light rubber flaps on it to let air through at freeway speed, and seal up at lower speeds and the fans on. Then close up the front a bit between the grill and radiator to give the air no place but through the radiator.

Mark just curious what or how are you to "close up" the front. Are you using some kind of material or moving components?
