So any answer as to how exactly this improves the truck, besides taking a whole 10lbs off? i still dont get how taking off the AC is beneficial and what to do with the hoses when you do?

The point of removing the A/C compressor would be to lessen the drag on the accessory drive, which will increase throttle response and squeeze some hp out of it.
Does anybody know if you can get rid of the AC/idler pulley all together? I already got rid of my mech fan and its pulley. Now that i'm thinking about it i may fab up a bracket to replace my ac with the alt. hmmm

The reason for running both A/C and heat at the same time on defrost is that the A/C both cools and dries the air. When that air is then heated, it is capable of absorbing more moisture from the windows more quickly.
I was really impressed with how much performance I was able to get from a lightweight underdrive pulley on my 300zx. It cuts parasitic drag by a safe 15%, but it also cut 10lbs of mass off of the engine. I couldn't find the equivalent for Cherokee.

My 90 cherokee didn't come with a/c and it uses an idler pulley in place of the compressor. So they do exist if anyone was wondering.

The hoses unscrew, Take them loose and toss them. The electrical connection can be taped up. The condenser (in front of the radiator) can then be removed and increase your airflow to the radiator. Less drag on the motor, less weight (minimal weight loss), less cluttered engine bay.
My air has never worked, and no condenser or hoses there, I intend on turning the pump in to a compressor set-up though rather than go with an idler pulley.

to answer the question of why in case it hasnt been already, it that most ppl that take it out use the spot where the compressor was to mount either a second alternator or move the alternator from the worst spot ever for wheelers(bottom of the motor!
) so it doesnt get too wet
