How to Improve LXi Engine Cooling Performance

[davidbrady]

Hish gave me an idea. Why not come up with an articulating cover mounted on the under-radiator shrouding that lets fan air exhaust thru the cover when the bus is underway and that seals closed when the bus is stationary. This way we get great breathing for better cooling when the bus is moving and we stop hot air re-circulation when the bus is stopped or in stop and go traffic. Hish did something similar in his early days at Chrysler and if I got his explanation correct I think his system opened using ram air; it was a passive system. I don't think I'm smart enough to do that but I can picture a powered louver that opens and closes under operator control, or a speed sensor to do the control automatically. Any ideas for parts or contraptions? Perhaps something like this: McMaster-Carr Louvers.
