But with that said, new cars have underbelly pans and open grills so the designed (on new cars) air flow works correctly.

I'll do an undertray at some point. But... are those resonators or catalytic converters on the exhaust pipes just aft of the engine bay? With grills blocked and the belly enclosed, I would think heat builds up more, especially if the CAT is still in the bay, no? These cars have more cooling capacity in some other way? Better pump or radiator?

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
