Here is a few pics of the twin electric fan setup i installed a few weeks ago.
Personally i hate the idea of the water pump turning a fan to keep air flowing i know it works but it looks ugly as hell and adds resistance to the engine, i know its very little but i just don't like it, its a old fashioned thing that should be left with old cars.
So i have a 56mm alloy rad, and a twin electric fan from a AU Falcon installed which works exceptionally well.
The reason for choosing this fan setup over two basic Chinese fans is that alot of muscle car owners along with Off-Roaders and other Nissans use this and do so for a reason, it has two 340mm fans and the fans blades themselves are far more efficient at flowing air then most other fan setups, the shroud has a median divider so even running one fan at a time is sucking air through half of the rad. Im not sure on the airflow rate but its way more then the stock setup. The shroud measures roughly 460mm x 640mm which fits my rad rather well. Finished it takes up 90mm still leaving 110mm to the crank pulley, And not being cheap Chinese fans they will last a hell of alot longer
Best part is that i got the setup for $60 NZD
For now the fan on the turbo side of the rad is wired into the stock thermo switch, in the near future i will change this as the stock cut in is too high. The battery side fan is wired to a switch on the dash as i want control for times like when you are sitting in traffic, if you dont want the fans switching on off on off. The dash switch is wired through a 25amp fuse, might be a bit low but will see how it goes.
To make the shroud fit i had to cut away are area for the bottom return hose and the top feed hose, also cut away an area to fit the BOV pipe.
i simply cut off the plastic tab on the top and made holes to bolt this onto the rad, on the bottom i just simply cable tied it too the bottom tank, this did not require putting cable ties onto any of the core, so its very secure, you could make brackets if you really wanted to.
