Turbo or air cooler

Pipes. Check them all

 

It can whistle but that doesn't necessarily mean the compressed air is actually being fed into the engine.. are you going by the sound or do you have a gauge that shows what psi you are actually making?

 

Should be 4 boots and two pipes. Also check the lines going to your air compressor.

 

Ya
Spinning like hell and not returning the boost to the engine

I think maybe I was thinking this can cause turbo overspeed

 

Stop driving it. You will burn up your turbo if you stay on the throttle

 

I'm not sure you need tow yet. Company driver ?
