Pics of the twin 16" fans Rainsey.
Not suggesting this is the way you should go as I'm unsure of your usage plans mate. In regards shrouds for electric fans it is my belief that they are already built into them and with a twin setup I'd say my custom fat brass radiator appears at least 80% covered. Space wise with a GU 6.5 conversion I reckon a shroud would be near flat blocking sheet metal anyway.
One very important lesson I've learnt the hard way on previous rigs is to never use those electric fan push through radiator zips or bolts with fender washers sometimes also supplied. They will destroy a radiators cores in off-road conditions IMO. Weld up proper mounting rails to bolt to and keep the fans just a few mm off touching the radiator. Pic below also of the 'Derale' control unit for the fans.
It has some great positives but also some quirks that I'm trying to adjust/iron out. Positive 1&2 are that it only requires 1 x sender and also auto kicks the second fan on 10F higher for emergencies. Issues are that it requires 10F below fan 1 kick off to turn off fan 2. I have combated this by a 60 sec full shutdown reset of its brain whilst coasting along. Once all cooling mods are done it should be ok but I'm thinking 2 x seperate senders with seperate adjustments each would be better. Cheers!
