Just for so everyone knows, I never had a fan shroud on my car when I put my electric fan on there..
Never had a heating problem ever.. I really don't feel a fan shroud is a nessecity with an electric fan placed directly onto the radiator.
If you have overheating probs without a shroud and with an electric fan its most probably due to an insufficiently sized fan..
If you don't have a shroud on your radiator, it is relying entirly on air flow through the front of the car and over the radiator, the fan should only really come on when stationary or when moving slowly in traffic or something..
....IMHO

I think you have a very efficient radiator, and do not do very much low speed driving. Fan shrouds do work, they have been proven many times over. I am glad your setup works, but I think you are the exception - not the norm.

I had an OEM twin-fan set-up from a wrecker on my Cosmo. Because of the Cosmo's rectangular radiator, this fit perfectly on the core. It was unshrouded and worked perfectly. And I got stuck in traffic nearly every day...
If you have a fan that is as big as will fit on the core and pulls a decent amount of air, and it sits hard against the core (no gap around the outer ring) then you're pulling air through most of the core anyway. A shroud isn't going to make a huge difference.
Try it and see. Make sure it's installed propery, and if it keeps the temp needle where it normally sits, you're fine.
