How much horsepower does the belt load steal, vs. the electric driven. It would be interesting to see the comparison.

If there is no clutch on the fan it represents a constant load so an electric fan running off a thermostatic switch is a lower engine load. If the electric fan is always on it's probably about the same load as a belt driven fan without a clutch. If the belt driven fan is on a clutch then there's probably little or no difference between it and an electric fan running on a thermostatic switch.
The point is we're talking about 2-3 HP. Can anyone here honestly tell the difference when the motor is banging out 300hp? I doubt it. It's just 1% of the total output and it get's even more rediculous when you start arguing about trucks made to run at the track. The 572 in my 67 C-10 is putting out somewhere north of 650 Hp. I can't tell the difference between 600 and 650 cause the whole shootin match is limited by tires!
