So what I was trying to say is that a fan installed closer to the radiator will not provide any more airflow then one further away. (Installed in a shroud) By elevating the fan you eliminate the dead zone and pull the air through the radiator surface that was once covered by it. Different people have different opinions as to the proper elevation height.
As for smoke testing, this is something that can be benificial as I have used it for wind tunnel testing 1/10th scale model vehicles. But I am not in school any more and the information I obtained in aerodynamics 400 whatever is a little rusty.
Oh and thanks for the info Bill, it will make a great sig!!!
