If I remove the fan access door completely I have a radiator (single) built to fit the entire space, it looks like I would have almost twice the cooking area. I would remove the stock fans & rads and cool with 4 electric fans with the appropriate shrouds. access through the old side radiator inlet air ducts, which would be covered by a solid door to force the air down over the engine like the original design.TOM
The negative pressure is strictly a guess on my part. I was just thinking of all the dirt that gets sucked onto the back of the bus and how much gets on our toad. Maybe someone can enlighten us on just what all that air we are pushing through does when it gets to the back of the bus. Anyone got a wind tunnel big enough for a bus? LOL Jack
