I think it's likely you're going to see some improvement if only because it's a big grille block. It would be interesting to see coastdown results....

The only suggestion I can make is to perhaps tape the top edges of the dam to the bumper (white duct tape?) so that edge (with the small gap behind it) isn't exposed.

Good luck on your trip this weekend!
