Without phasing the push / pull fans, you can actually end up with LOWER airflow than a single fan..
I also dont have much room in front of the radiator as it is mounted right near the front of the truck chassis..
I figure if a OEM mechanically driven fan is pulling 8000-10,000CFM through a 90mm (3 inch) core on a truck..fully ducted..I need at least 1.5 times that CFM for a 180mm core (6 inchs of core!)
The only fans I can find that meet that are the Horton units...and being able to direct drive from the crank, and avoid frictional losses through a belt driven oem fan, I should also gain a small amount in savings on that
