Looking to replace my clutch fan assembly with an electric. Searched the forum, but didn't really find the answers I'm looking for. First, how many cfm is really needed, obviously, more is better, but how much is enough? Second, considering the Flex-a-lite 294(dual fan setup), 6000cfm, but it draws 28-36amps- is the 117amp alternator that is stock enough for this, or will I need to swap out for the 136amp? BTW- I live in Florida, so I need enough air flow for the AC condenser. Thanks for any help.
