Squeek Noise From Turbo?

[worzeel]

Hi,

I have had my XR6 Turbo for about a month now, and I was just wondering if it was normal for it to do a squeeking sort of noise under hard acceleration.

Its a 2003 4 speed auto, sometimes if I plant my foot from around 50km/hr or so, when it changes gear, I think the turbo makes a squeek sort of noise... it sounds like a BOV... is this normal? Its different to the flutter noise I sometimes hear when I let off the accelerator at around 3000rpm.

I will try and get a video of my car, to see if you can hear it on the video...

You sure it's the turbo? Could be belt slip when shifting at high rpm.

Does it happen as you accelerate or just when you change gear?

Just when changing gears....

Could be a belt slipping though... but would it always make the noise if its belt slip? cause it doesnt always make the noise

From my experience turbos don't generally make a one off squeek when the car is shifting gears, usually a continuous squeel or howl when boosting. My old BA use to every now and then give a squeek when shifting at high rpm from belt slip.

I'm no expert but might be something for you to consider.

I noticed this morning when I helped my cousin do the paper run (needed to stop lots of times)... sometimes when I went to take off, the engine would just rev, and slowly move, but then once it started moving, then the car just went fine... untill I stopped, and waiting there for a cpl minutes, then would do same thing (rev high / move slow, then go properly).

Is this something with the belt also? or is it something else :o

sounds like your tranny

mine makes a squeek noise 2nd to 3rd sounds very strange...

The slow take off would have nothing to do with the belt. Would have to be a something with the trans, but what that is I don't know.
