Mine is my daily driver to since I still have the ac pulley It still blows air just like a fan does and it's good enough for me.

Nice. and 30 pounds total. Plus the few horsepower it freed up like maybe 5 to 8. But hey every pound and every horsepower adds up..

It removes weight, however no power is "freed up". If the AC is off the compressor clutch pulley is just a free-wheeling idler, and the PCM turns the compressor off at WOT and any load greater than 70%...

Id like to know how u remove an ac compressor w/o a pulley. I mean if u delete the compressor u would delete the pulley as well unleas u are talkin in terms of the ac system. And cliff is right ac compressor is a dead pulley or idler as long as the ac clutch isnt on.

Of coarse it's probably a dead pulley though some people say it isn't I pulled mine of due to weight reduction. Also frees up a few horsepower and weight at the same time which realyl together adds up 30 pounds plus the extra horsepower it frees up. Yes it is worth it to me. Every little pound counts and the more Reduction the bigger my wheelie gets

It frees no HP if the AC is kept off, or switched off by the PCM at throttle positions of more than 75-80% open--none, nada, zippo...

this is y i asked the dumb question, u said u still had the ac pulley which to me means u didnt delete the compressor, so its still a dead pulley which isnt any hp freed up at all, weight however if u deleted all the ac but the compressor u deff freed up some weight.

along with deleting the compressor u have to get a shorter drive belt now to power everything else, which im sure cliffyk should know what belt would do the job.
