So i went WOT today, and afterwards i noticed that i have this whining sound like a high pitch turbo as rpm's increase, but it isnt noticeable at idle. i popped the hood and it sounds like the altenator or p.s. pump area. It still steers fine but i dont ever recall hearing this sound this loud before. Any opinions? how much is a new pump and how hard is it to install? The car only has 54k miles, and they are mainly highway.

 

it really sounds like a supercharger is under the hood (LITERALLY!) and it is freaking me out, so does anyone have any suggestions? I have one thing to add, i tried to suck out some of my old fluid with a tukey baster and put in some new stuff about a month ago so..........

 

well i WAS going to say air pump but thats driveside...

check for loose turbos and superchargers


then id say your right. Not much over there aside from an alternator and PS pump and PS pumps do sound like that on thier way out

 

they also sound like that when they are low on fluid...check that if you haven't already.
