Lots of interesting ideas on this swap. I can see this being of some benefit to drag racers how much is going to depend on the ambient temps and amount of power the mechanical fan would use. As far as MPG are concerned Toyota would commit murders to gain .3 mpg's in a 5.7 truck. If they could get even close to 1 mpg fleet improvement and have similar reliability as the clutch fan we'd all have electric fans from the factory. Alternators use plenty of power too, my guess is in terms of power consumed over the long haul per BTU of cooling the mechanical fan is better.
It would be interesting to see how this setup does with 8K lbs of trailer behind it going up some long grades in the summer with the AC. If anyone has this setup and tows let us know how you make out.
