Nope, no AC yet. I don't think you can beat the 7 blade for volume of air moved. When I stand in front of the car with a loose t-shirt, it'll actually suck the t-shirt up against the grille. I think the key is to have a good tight fitting shroud, tight all around the radiator's outer edges (to utilize all of the radiator), and tight around the fan. And if you want to get really anal, the radiator should be sealed all around to force 100% of the air flow through the radiator.
Now, the electric fan is really nice for cooling after you shut the engine off. Good luck!
