    04 gtp supercharger problems

    I have a 04 gtp with 111,000 miles on it. The supercharger started making a whining sound when it "kicks in". Kind of sounds like an air leak. I changed the air filter and checked the supercharger oil and all is good. Any info or advice would be appreciated. Thanks

    I'm just going to start off with the obvious. It's not the supercharger's whine right?

    How long have you owned the car?

    Blow up a balloon and stretch the mouth of it while you let the air out. That's about the closest description of it that I can think of. Could it possibly be a vacum leak?

    As I imagine the sound of the balloon I can't help but think it's like the normal supercharger's whine, such as:








    Sorry if it's getting repetitive. I just haven't heard a description that doesn't fit supercharger whine yet.

    It is a higher pitch sound than what normal would be. It gets louder the more gas you apply.

    could it be something internal in the supercharger?

    Idler pulley.

    Bearings on the inside could be wearing out/out of bearing grease and causing the noise.

    PCV on pass side upper intake I believe....doesn't sound like a supercharger bearing...you should be able to tell the difference.

    Re: 04 gtp supercharger problems

    So i changed the pcv valve and found a bad s.c. idler [grooved one]. It didn't help. With the s.c. belt off the noise was still there but very faint. The belts don't look to bad maybe a little glaze. Suppose i'll check motor pulleys and try new belts. Maybe belts are slipping? Thanks for all the ideas; any more?

    That sounds a bit loud in the beginning compared to my father's but it is such a nice sound

    I have heard the serpentine belt tension idler make a whine noise when the bearings are shot. Have you checked this?
