Inner fender removal for weight reduction?
Not only does it allow pressurized air to flow out of the engine compartment it also drops the heat in the engine compartment 5-10 degrees. The flat firewall acting as a piece of plywood I would disagree. The floor pan pushes the air coming through the radiator under the car
. The air above that gets trapped. Raising the hood lets it out. Opening the sides also lets it out. As far as wheels acting as fans? CSX's had pumper wheels there were lefts and rights . They forced air inward and were used to cool the brakes.
My experience,
I added a air scoop under the bumper for cooling. I was on a hard pull up hill. Wound second to 8500 and was pulling hard in drive . At about 120 mph the RPM's climbed like the trans left go. I left off and the next thing was loss of steering. Air got under the car and lifted it. I never experienced anything like that ever. I removed the air scoop under the bumper and lifted the hood and the car stayed on the ground.
The trapped air caused lift. It was not from the scoop it is sealed to the breather.
The best way to eliminate engine compartment drag is a one piece front.
I will be using one now on the new build
