Air movement, How much air does a 911 fan move Options

[914 Ranch]

There's got to be a number on that somewhere. I know that there are a few different fans but what I was thinking about is how many CFM do they move. I was just thinking about the air flow out of the back of a car. If the air exiting from the engine is so high that I can't remove it from the car that I will need to move it out through some sort of diffuser. I would like to have no air build up under the rear of the car. Speaking of exhaust I have no idea what I'm going to do for it. And all of this still will need a diffuser. The fans in the oil cooler move 3200 CFM, I am just hoping that that would be enough.

It would be interesting to see how the rear section of that PMS pan mates to the underside of the engine. guiding the air flow away from the bottom of the cylinders and preventing the airflow from being trapped in the rear section of the under pan would be essential in making this whole package work effectively.

It is sometimes overlooked that cooling airflow that flows through the car creates as much drag as the air that flows around the car ( of course relative to the volume of the flow). That is why so much engineering is put into the design of cooling air exits in race planes and high end race cars like F1. Guiding that cooling air out and returning it smoothly to the surrounding airflow can produce significant reductions in drag and improvements in cooling
