Is it possible to block entire upper grille & still draw on the pressure air coming up from the lower grille, giving you both advantages?
If all holes around radiator are blocked, there is still a large pressure build up in front of the radiator from just the lower grille anyway.
I have seen this with both my vehicles after upper grille blocking.
