Ugly whining noise while accelerating only

[ichiban]

Here is the best way i can describe my problem. When I decide to push really hard on my gas pedal the car does go, but after a few secs around the 5k RPM range it makes a really loud whining noise. To the best of my knowledge it sounds like it is coming from the front of the car. I have an AT, NT. The only reason i know about this is because i was leaving my friends house and sped off and than he called me and was like WTF is that noise coming from your car. He told me it sounds like a really bad whistle/whine. So than when i was driving home i would punch the car and would hear it. I have no idea where to start looking to figure this out. Any ideas where to start would be much appreciated. I have tried to search for something similar to this but came up with nothing. found things about BOV and other things but nothing with my problems. This noise does not happen instantly. It takes a while but most of the time around 5k. than it goes away. wierd.

I'd start by pullng your upper timing cover and making sure that the timing belt isn't rubbing on anything under acceleration. You may also want to check your other pullies for the accessory belts as well.

Keep us posted,

take of the accesory belts and spin each pulley.. i bet your alternator is stuck

I checked all the belts and pulleys... there are all find..... i thought it was the front where the noise is coming from.. but now I can tell it is coming from the rear... Only when I accelerate real hard. the noise is like a loud whistle..... any sugestions would be much appreciated...
