So i have an electric fan to keep the car cool at idle, but it just doesn't move enough air. Currently i have a 14" pusher (there isn't any room for a puller) that is shrouded and rated at 1585 cfm. I'm looking to step it up to a fan that moves more air. The next step up in a 14" dia. is a Perma-Cool that doesn't have a shroud. It's rated at 2950 cfm. I'm thinking that this fan will be much better, but i'm wondering why it's unshrouded. Does it make any difference? (since it'll be set up as a pusher...I'm thinking the unshrouded one may actually be more efficient since it doesn't have to pull the air through the shroud..but i'd like to hear some other opinions.)
Or, i could do this....run two 10" pushers and cover more area, but combined they only move 2500 cfm. This may actually be better..but i'm just not sure.
What do ya'll think?
