Cooling issues

Is your radiator support to hood seal in place? How about your lower splash pan to radiator support seal? Without those, there is no way to funnel the air into the radiator opening. It’s like sucking through a straw with a hole in it. The idea of air flow is to trap the air in front of the radiator, use a conical shaped shroud and clutch fan to draw the air through the radiator like a vacuum. The fan needs to be in the shroud at least 1/3 of the way, otherwise you are just blowing air around and not drawing it through the radiator. The pusher fans and flex fan are not doing you any service if you are not funneling the air through the radiator.
