I just installed this setup on my rig and I am very happy with it. The fans are mounted close enough to the radiator that they don't require a shroud. Very high quality parts at a very fair price.

I thought about doing something like this, but I've read in numerous places that on an off-road vehicle, you don't want to mount the fan(s) directly to the core. I suppose the fear of flexing the chassis/radiator is the only real reason. Regardless, most 14" fans will be too large to do it anyway.
the belt is routed as stock except goes crank to alt.
I thought about this as well, but decided there wasn't enough belt wrap around the crank and alternator to be comfortable running it.
While it's a great idea and all, not having a shroud is like pissing in the wind. In the hot summer, it will not work. Secondly, it's VERY dangerous. You can get a 2200cfm electric fan with shroud on ebay (fits like it was made for the XJ) for $29.00
A for effort, but F for functionality.
I will happily address the valid concerns you raised:
1) A shroud definitely improves fan efficiency, no doubt about that.
2) I said multiple times I want to add a shroud, so don't imply I'm avoiding one intentionally, or don't think they work.
3) In summer, in Florida, with 100*F temps and 95% RH, I am 100% confident this will keep my Jeep cooler than the OE setup.
4) While an open fan isn't the best idea, it's only dangerous if strangers are playing in my engine bay with the ignition on.
5) Any 2200 CFM fan for $29 isn't going to last/perform. You get what you pay for, everyone knows that.
6) This setup, while it certainly could be improved, functions quite well as it sits.
Note to all: I respect other people's opinions, and will address concerns as best I can, but please don't ruin my thread with your bull$hit.
