Bonneville Landspeed Racing - Let's Try a Thing.

Block it off. The 2-3 mph you’ll pick up is worth it. Race cars don’t have fresh air vents.
Use a Parker pumper and push fresh air in to your helmet.
Sorry for the confusion. What i meant was for any street driving, it could be made to work.

I also wonder about removing the door handles and adding ones like drag cars now that the vent windows are gone. Top of door at the vent windows area I wonder what a 4-5" hole in the window would do aero wise in that area??? Could it still net a gain over the stock door handles?
