Rear mount rad fans

[Batfastard]

Is one big fan better than two smaller fans . I have a twin fan set up at tge mo but want the upgrade .

Which ever covers the most area and moves the most air. Unless your radiator is square 2 fans will most likely cover it better either way it will work better if will shrouded.

must have a shroud..
do the dropped paper test
set fan one up with it running full and drop a sheet of paper down it front of the rad, keep moving the paper away until the draw no longer pulls on the paper then repeat on the second set up.
if concerned about the width repeat test on the outer edges of the rad as well. you will be able to see if there's any major difference or not

Just going through with my truck. More of an issue (assuming you're doing the 1000 again) is airflow to the rad. I think I'll have to bring scoop to above windscreen on mine and you'll probably be the same.

warm day = delta T is shite, meaning not enough available cool air onto your radiator. lowbox = lack of airflow over said radiator compounding matters.. long story short, a better shrouded fan and the radiator moved away from the body a bit with some effective ducting would be for the win..
