Lets hope so mate cos at 1bar if its not it will let go!
If i was you i'd take it off or pay someone to take it off and check for steel internals it wont cost alot, however if its standard and running 1bar you have a big bill coming mate!
That sound mate you sure its not DET?

17psi is closer to 1.2bar.

Whip the intake pipe off and have a look at the compressor nut and spin the wheel.

what should the nut look like muilt spline or somthing
its not det its the turbo when it spins up or down same as my old scooby with a rollerbearing turbo if i get hold of a magnet would that stick to the compressor wheel
