Trying to get it mostly right the first time: A 5.9 Magnum, 46RE swapped and tummy tucked daily driver TJ

I set the AA motor mounts where the kit intended them to go and while it allowed several OEM parts to bolt back on it greatly limited what I could install due to the distance from the water pump pulley to the radiator. The 16" fan I'd run previously would move a lot of air (1400CFM, from memory) but it lacked in the static pressure to pull the air through the radiator. The only way to get a fan capable of a higher static pressure was to install 2 smaller diameter fans on either side of the water pump pulley.

Each fan pulls 12.9 amps max.

We've talked about this A LOT over the past few years... The SPAL new brushless fans seem to move more air. The 300 CFM one that came on my radiator seemed to be enough with the Magnum engine but it doesn't seem to be adequate for the Hemi so I've stepped up to the BIG DOG.... This Camero SPAL brushless is a 850 watt monster.

I hear you about the space - same for me with not much room between the Hemi water pump and the radiator. Something less than 4" if I recall.

This is the fan that I run: Spal 500 watt brushless, draws something like 41 amps. It's the only thing I've found so far that can keep up with the heat on the Hemi (plus the A/C condenser, and the tranny and hydro coolers sitting in front of it), and it's the only one I've found that is narrow enough to fit that tight space. It's something like 3 or 3.5" deep. It's also a nesting type fan, so it mounts recessed into the shroud - which seems to work well at moving air across the entire radiator.

Here it is in-situ:

Hopefully your setup works for you, but man, just looking at it seems like it can't possibly move enough air. Most folks who run dual fans run them in front of wide rectangular radiator - like the XJ. Since ours are basically square, a single large fan has much more surface area than two smaller fans.

Keep us posted on how it works, and good luck with the setup. Keeping these big V8's cool is always fun.

Not sure if you are in the market for a radiator or not but here is what I bought.

They have one with an electric fan option as well. you might check them out.
