Not true.
When the AC is not on, the pulley is free spinning and has little to no effect on parasitic load.

The only "good" it does is to lighten the weight of the vehicle slightly.
IMHO.

I agree with this. The pulley just freewheels when the A/C is not on. So if you remove all the A/C stuff you wont get any more power but you will eliminate about 50 lbs from the front of the car.

Removing the A/C also simplifies installing a TMIC and makes a LOT more room in the engine compartment

I like it because it gave me a place to put the coolant tank on my car.

seems to make sense but it seemed to help me out when i got rid of mine. i was able to go up a mountain without having to shift down to 3rd, was able to stay in 4TH. also freed up the engine bay a good bit

taking the belt will do very little. the a/c cuts out when you get on it anyways. but, that copressor is heavy. you can also rip out the exchanger, wires, tubing ect. i've enjoyed this mod.
and if you can fab up a bracket for the alternator, you can get rid of that big cluncky cast iron stock one.
