I finally was able to jump start my car (after checking over all the wiring). So when I went on a 'test drive' I hear this soft high pitched whistle sound that is linked to the accelerator pedal. The more I push it down, the more I hear the soft whistle sound...(I didn't go WOT though...just cruised around...boost guage didn't go above 1 psi).

Do I have a vacuum leak? I did leave my car out in the cold for a few days...so my hoses could have frozen and expanded a little?

OH, I have a turbo running at 5 psi.

I really didn't notice this before...but then again I never left my car out in the cold for so long either...

But the thing is, I never heard that sound before on my car after putting the turbo... But on my friend's stock Talon TSI AWD I do hear that sound...

Maybe it is the turbo? ;)

I just hope it ain't fuel pressure leaking or something?

Do you hear a sound like that?

thats what a turbo sounds like when its spooling...its sounds like a whistle and you feel like your car is going into warp drive(star trek thingy) usually around 2-3k for me

sounds like it is the turbo spooling....it should sound really nice soft whistle pitch. Good luck

This sound is common all the time to the turbo guys with a boost leak. Check your pipe connections.

Ever blow a LOT of air through a thin slit? (whistle!)

Ya, I'd check all your lines, and pipe connections. Make sure your BOV is screwed all the way down too. You will know if its the turbo spooling up, cause it will sound cooler then shit!:-) When I first heard my turbo spooling up, I almost... never mind.

If it is an air leak you can definatly tell the difference.
Its a mad rush of air. The turbo spooling up happnes when there is a light load on the motor (20% THR) and slowly accelerating from 2-3.5kRPM.
An air leak will only get louder as you put oyur foot down farthur to accelerate.

I think I have an air leak in that case...cause I hear that noise even before load (when I step on throttle 5%, 10%, etc).

Just to make sure, load happens when you see the boost guage read over 0 psi ?
