They called me--I ordered the dual fans--and said that the single fan has greater cfm, so I 'upgraded' for no cost. Before I agreed I checked the mfr website and the single fan does have greater cfm and less amps (by 2 amps, I think). Also, on their FAQ, it says the shroud should not cover the whole radiator to allow air to easily go around the shroud at higher speeds.


DID I SCREW UP?!

 

Shoot....maybe I screwed
I throw the single fan on and we shall see what happens. Smack dab right in the middle

 

i really think the shroud should cover the whole radiator, if not at low speed/stopped the fan will not pull air across the whole radiator. jmho

 

i had 2 fans with no shroud direct on my rad on the d1 they seemed fine but i could not get the temp switch right and it was mounted in the thermostat housing would start coming on and off at different temps ( using gm 1 wire fan switch with a relay)

keeping tabs on this as i want rid of my clutch fan

 

Well since the single fan is supposed to be an upgrade I think ill just use it for now and see how thing turn out. Honestly right now anything would be better than the clutch fan full shroud or not.

 

Is there enough room to mount 2 of those singe fans? For the ultimate upgrade?

 

Not enough room to run two....

 

That shroud coverage looks very poor, especially left/right.

 

it look like 20% of the rad is not going to get air at idle or a stop.

 

I wanted to buy a set up, so I messaged them. Here is the response:

"ffd changed up there systems on a few vehicles this year and land rover was one of them,the older system was a two fan and the 2015 systems are single fan. it had to do with geting more air thrlough the radiator at highway speeds so they went to smaller shrouds. you can email ffd and see if they have or can build you the older system but we only have the newer ones in stock now."
