Electric fan in lieu of Flex Fan

You try to get as much air passing through the rad. as possible and let the fans do all the work. But remember they are pulling 60 amps for both. So adjust your alternator if needed. Mopars put out max 80-90 amps at high rev and 30-40 at idle. Thats why we pull a 155 amp on the giveaway car. With a small pulley it puts out 90 amp at idle.
