Advice on choosing fan
I have 4 fans on the shelf to choose from.
318 in a Duster. 22” 3 row radiator. 75% street/ 25% strip car.
#1 - 7 blade 19.5”, 2.75” pitch, PN 3462186
#2 - 5 blade 20”, 2.375” pitch, P20118 (off of 85 Dodge truck)
#3 - 7 blade 19”, 2.25” pitch, numbers are 914692L75 and 3991431
#4 - 6 blade 18”, 2.5” pitch, steel center with aluminum fins.
I shift at 6k when racing. Currently running 2 10” electric fans and they aren’t always adequate when the temps climb above 80*.
Which fan would you choose and why?
