I'm not running a p.s. cooler and I'm not even sure this is my problem to be honest. But, has anyone else experienced this? If so, what were your symptoms?

 

unfortunately this isn't an uncommon problem:

Actually, you ARE running one. Most people replace the OEM cooler with a larger version.

Here's a couple of DIYs on replacing it.

You can also pick up a NISMO PS cooler for around $150, it's a direct plug-in replacement. It's about twice the size of the OEM cooler.

 

after reading the threads i don't think this is my problem. I've got a whine noise/drone coming from the ar ONLY when giving it gas. Sounds like a supercharger. Hard to pinpoint where the noise is coming from b/c of the drone.

After leaving the track and slowly drivin home it seemed toget better....or maybe I was getting used to the noise? I dunno.

 

whining noise, especially if it's RPM dependent, can definitely indicate a problem with the PS pump.

 

might be a bad ground, do you have an aftermarket head unit?

 

no stereo.

 

yeah, I bet you roasted the fluid in the pump. My guess it's better but not completely gone, and then a fluid change will make it quiet again. But it's overheating on the track.

 

i'll try doing a flush at work to see if it helps at all. I'll keep you all updated. thanks for the help!

 

do Jason's DIY setup and get some nice synthetic ATF fluid from Redline or something...hopefully your pump is ok.

 

not the p.s. drove it last night after it had been sitting for a few days and still made the noise. so hard to pinpoint b/c of the drone. damn this car!

 

did you change the fluid? Remember that you probably scorched the fluid that's in there.
