Hi Steve,

On my xA, I found I had better cooling with the upper grill block complete. And you'll want to experiment with a cover on the "chin" opening, which will force the air to flow through the radiator, and not vent out the opening -- but this might end being like your belly pan. You have to balance the grill opening size and the the amount of air you let out.

But in the end, I think anything you do to restrict the air flow through the engine compartment helps your belly pan work better, and any air that you can deflect up and over the hood/car helps, too.
