Cant say I can positivly pinpoint the noise to my S/C, but my car has been making different noises the last couple days. When I blip/ go WOT I can hear a noise that sounds like a Crank driven coolent fan. Like a whooshing/winding down kinda noise. But it doesnt always make the noise, just every now and then. Does anybody have any kinda Idea of what it might be...

 

Nobody has any in-put???

 

have you checked the mounts? and it's almost 3:30AM over here :p. I think a lot of people are sleeping
