Going to mount up the Spal 12" pusher fan I picked up this weekend, there isn't a whole lot of information about shrouding pusher fans.
Since I'm only running the one fan (left half of the radiator), I want to know if it's worth fabricating a shround into the fan mounts to cover this half of the rad, and leave the other half without the fan as is (obviously!).
I will be making up trim pieces to go around the whole radiator to ensure as much of the incoming air is being forced through the core, and once i have fabricated the manifold and mounted the turbo, to work out a method of ducting the right half (no fan side) of the radiator either out through the bonnet or underneath the car.
It's not going to sit in traffic, so i'm not concerned about having to run 2 fans as one should keep it cool at idle and low speed. There is no AC condensor in the way either.
I will be going to a thicker custom rad at some stage, but not just yet.
To shroud or not to shroud?
