Ok, so what increases / decreases does everyone have on this ? I know I will drop 50-75 lbs and all that (maybe more) I want to keep the bare minumum for defrost and straight air from outside.... Maybe just keep the compressor ? But what increases / gains would I see by getting rid of it ? I know I will need a new belt, timing, pulleys ? Suprised I was unable to find anything on it. Just a thought as I will be doing in on a weekend when the wife is not around
our cars timing dose not around the ac. When the compressor is not engaged im sure it robs a little power....but engaged with the ac on i have heard up to 15-20hp lost not to mention mpg. Our cars weight around 3000lbs with 224 hp that gives us a power to weight of 13.39. so every 13 pounds you remove from your car frees up a horse making it that much easier for your engine to pull it around. id say the compressor lines condensor and some of the wiring could put you in at 75+ lbs. removing that much weight you would feel the difference of about 6hp. but i think you could feel more becuase you are taking drag off of the crank by removing the compressor and putting in a shorter belt so if a full pulley kit gives you 12. we can guess removing compressor and shorter belt could give you 6hp. removing the ac completely could net you up to 12hp.....in theory.....
I'm not entirely sure about on the Subaru, but i've always heard people wanting to disconnect the A/C for more power, when in reality, sometimes you gain like what, 3hp? My 86' Corolla has the A/C belt off, and i didn't notice anything at all...
