What is blown to pieces?

[Kroegarn]

Popped a hose at the highway, yesterday, running high boost and speed. Got the hose properly back, but now the car has no boost, zero, nada, noll, inget.

Checked the turbo at the compressor side and it looked fine, no unwanted sound or rattleling. The car is running superfine except the lack of boost. Could I have destroyed the turbine blades or?

Just looking for some hints since I wont be able to pressurize the system for leak check until monday.

Will check the turbine side tonight so that I won´t have to go all weekend worrying about a broken turbo

Hopefully it didn't overspin when the hose blew off

Now I´m in desperate need of some insight and ideas of where my boost has hidden.

I´ve checked the turbo. Impellers are fine and the shaft is not broken, nor is there any noise.

The wastegate is closed and takes some effort to open by hand.

Changed the bypass to one that I´m not totally sure of the status. Only that is was harder to open than the one on the car.

Althoug I´m not even getting wg spring pressure I disconnected the multitempsensor contact with no change.

I´m going to check for airleaks next but should´nt the car run bad if MAF measured air are lost on the way to combustion? Anyhow that is my only idea left

Cracks in the tubular manifold?? Should´nt I hear that and at least some boost should make its way to the turbo.

Help plz

Could it be the water temp switch under the inlet manifold? I heard this sensor can affect boost.

Disconnected that one, although with it broken, that one will at least give you "wg spring boost" (what is that called?). I do not even have that.

I´ll check for leaks tomorrow and if there is´nt any I cant see anything else broken but the turbo .

Now I what is broken at least The turbon sealing seems to have given up. I lifted the top on the wg and moved the membrane up and down. The wooshing noise came from the compressor side of the turbo does not sound good to me

Buhuuuu just had to cry a bit
