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.

Those oil cooler fans are not moving 3200cfm when mounted on a cooler. Most aftermarket fans flow fans in open air, put a restriction on them and flow will plummet.
The problem with the 911 fan is airflow to the areas that need it. There has been plenty of information about putting that fan on a T4 and the issues associated with it. Also look on the Shoptalk Forum. https://www.spalautomotive.it/axial-fans |

The 1500 l/sec matches what I've read.
Are you looking to evacuate the spent cooling air from the engine area? Usually the air just needs a place to go - it doesn't necessarily need help getting out, unless you've closed off the underside of the engine bay or something. |
