Hi, got wheelhop and a burnt clutch at the drag strip this weekend and when I got home my car won't make any boost and I have this really weird sound. Will upload a few videos soon but here is a guy with the exact same sound.



What the hell have happened? Totally lost right now what to look for but I bet someone here know what it could be.

Have tried to search Google and a bit here but know what to search for. There is a million reasons for no boost but I can't find the issue I have (probably just me missing it). Have found 4 videos with the same fault but none of the have the answer to why it's like that

 

Have you visually inspected the turbos? I'm guessing maybe thats what a turbo with no compressor wheel would sound like - if that's even a thing.

 

Cant see how the compressor could come lose but have found allot of threads with the same noise in the same area (around the secondary turbo). Going to start looking for leaks there as that's what everyone is suggesting it could be.

 

Yeah i would have said leak too except that would have been too obvious and is usually a whooshing noise. Definitely the 1st thing to check though.

 

Ät the garage now tearing thru the pipes. But a smoke machine on it and found a few smaller leaks that I am searching for now will see what I find

 

Lost again the turbos are fine.... A bit of play on the primary turbo but nothing that would cause this. Had a bad hose on the actuator that switch the valve that let the secondary turbo to send air to the Y-pipe but not a big tear so don't think that's the issue..... What the hell can it be? I bet that there is someone here that knows.
