Hey, A new mod! smile Simple, too! See those vents in the rear bulkhead? I'll bet they let air out! The cabin vents would tend to pressurize the cabin, which would decrease the airflow through the vents. Install the outlet vents to equalize the cabin pressure and increase the flow from the air vents. Pretty slick, huh? grin
