no boost....?????
 
I was trying to help out a little but i'm not a mechanic...
So here is the problem: The engine seems good but i doubt theres boost at all. With the hood open reved the engine and there is this flapping sound from the secondary turbo(sort of like sticking a finger in a fan but not as bad/loud). There is no smoke whatsoever(blown turbo sign, right).
Well anyways, it was just a "casual inspection" and didnt see any vacum lines unhooked or cracks.
What could this be? The owner went to get the car looked at by a mechanic today but i'd like to know!
any and all suggestions are welcome!
TIA

Sounds like the chewed turbine blades to me. Pull the front and rear intlet elbow off and confirm visually. I lost some blades on a set about a year ago. Thats exactly what I describe the sound as. Stcking a playing card in a fan.....

Get some new turbos put on it.

Thats my suggestion.

Sorry I just woke up. Took me a second to think.
