E-fan setup. wondering how much air flow i need.
Hey all im wanting to build my own e-fan kit and i found a fan model i like but not sure If it has enough cfm
Its a 11" fan with 1450 cfm puller. How If i used 1 by it self for radiator cooling would it be enough? if not i could use 2 of them and put the a/c condesnor fan in front of it and push on to it. If 1450 is enough to cool the radiator i could just buy 2 of these and use one for a/c one for radiator and have them just pull air past the a/c system. Looking for save a couple bucks but want it done right. Thank u for your help.
Model is 06 f150 4.6 with factory ford upgrade to bigger tran's cooler and extra load spring and what ever else comes in that package not sure what they all add.
