I'd really love to see some dyno numbers on alot of this ****.

What? The alternator is turning harder?
The alternator load on the engine will be the same regardless of adding accessories that draw more power, just in bigger power draw cases like stereo amplifiers or winches it may not be able to provide all the power that is needed. An alternator does not have a clutch on it like an a/c compressor, which can load up the engine a little more when it engages. So, no, not extra cooling capacity--but slightly less load on the engine=more power, possibly cooler engine. Gain may be negligible, but it will be a gain no less.
Removing the fan/clutch will free up some load on the engine for less drag, plain and simple. I'm not sure of the gains of doing this, but it does make a lot of sense.
