Default Need some Efan answers

Hello all,

I did the search and looked through all the Efan thread and 90% of them were pertaining to install, my question is how much CFM is needed, i have found several different options that i could use that say they are capable of stand alone use and they range 2100 to 3200 CFM and every where between.

I have the heavy duty trans cooler on my truck so the trans cooler and ac condenser already have there own fan so how much flow would i need for just my engine cooling and not be way overkill and not get hot..

Thank you guys in advance.

Sorry I cant help with your questions bud... is doing an efan upgrade a pretty good mod for performance also on these 4th gen trucks? You would figure this would be done stock in this day in age... I was just curious as to what the benefits would be to doing this upgrade?
