I am looking at closing up some of the grill in my car for better aero dynamics.
Behind my radiator is a 19" diameter round opening in the fan shroud. Less when you consider the round hub of the electric fan.
If my grill is sealed to the front side of the radiator, is there any reason I need more opening in the center of the grill?
Thanks,
Dennis
