On the way home today in the turbo I heard a pop and then lost power and developed a whining noise.

When home, I took off all the pipework and had a look into the compressor and it seems ok. Shaft had normal play. I think a pipe might have popped a leak but why now do I have a whine? Similar to the noise this chap has.... http://www.youtube.com/watch?v=F_FXekG16vM&feature=related

I am able now to get full boost pressure but I get very little induction noise compared to before and have the whine.
Any ideas?

That's whatine sounded like when the bolts holding the exhaust housing worked loose and munched the turbine.

ah, so it's either really easy simple problem of hose loosening or a fooked compressor or turbine wheel.

When your turbine got munched were you still able to get full boost?

So finally got time to look at the car last night. Turned out to be the gasket between the two halves of the plenum. All sorted now. Cheers
