you probably wont notice the small loss if you do small commutes. to people that drive far and tack on 3-5k in less then a week it makes a difference. noticing how many you mailes you get to a tank, lets say the op gets about 400-450 miles to a tank and now gets about 300-350 is big
:whs:

I know that when I use my dads RAV4, if I am crusing down the highway with the AC off, and I hit the AC button I can actually feel it kick in, like its losing power. I know that is just a little 4banger but they do rob some power

yeah your right, im driving a jeep liberty right now and i can feel the compressor cycle LOL, same with my 4 banger mustang :D

On these trucks i wouldnt think it would matter, i asked about the cooling fan because i know they rob some big hp, i would like to dyno a truck with and without the fan on, but im guessing 30 hp or more of a loss. big semis loose roughly 50 hp on the dyno, there fans are similar but bigger.

Another reason i asked is last year i overcharged my a/c system and it made the fan run like ***in crazy

i think you would feel it more during city driving, thats when you can hear the fan go off the most.
