How to get dam air damn off?
My Bad, a little. That slot is part of the function of the damming, but in your case, the stuff you have is breaking-up the clean ram-air and it would not be much of a delta with that obstruction. When I installed hooks in the slot, I cut holes in the cover to just not loose any vacuum action.

If the dam is removed, the fast air flow pressure under the bumper will out pressure the air from the rad that is flowing over/around the engine trying to exit thur/to the vehicle's bottom. So in turn, less air thru the rad. The electric fan will help the situation a little. Does this make sense?
If I could find it, I would install a longer dam to compensate the obstruction of the ram-air thru the rad caused by large aux lamps, bumper guard, winch & stuff.
My 1/2 cents on the topic.

And Two, I have seen old trucks run without the entire bumper and not cause any issues.
And 3, The only time this effect would take place if it did would be when you have a significant amount speed causing wind pressure.
Also, I would think the fan would pull the same amount of air thru the radiator no matter what was in front of it, as long as nothing was flat up against it.
