radiator shroud and fans

nazgulMember

happy belated new year!!!

i have two new cooling fans i am going to install as sucker fans and am curious as to the better mounting method. should i mount them on rails or fabricate a shroud that would cover the entire back side of the radiator?

i do not want to mount the fans with any "through the core" fastening devices (much too easy to do).

if the shroud is the better route, about how close to the radiator can the shroud be, the greater the distance between the radiator face and the shroud results in air being pulled over a greater surface area of the radiator. but then the radiator must be leaned forward to a greater degree which directs the airflow less efficently (no hood vents).

without a shroud, it would seem that you get cooling air being passively forced through the radiator by the cars movement and by fan assist. whereas with a shroud, the passive airflow would be substantially, if not totally, reduced.

thoughts, opinions, suggestions????

thanks in advance
