turbo's and vacuum hoses

[sampson240sx]

I noticed a few hoses in the intake the connect to things that run off the vacuum for the intake, AKA vacuum hoses. I was wondering how these things work when they are pressurized by a turbo/super charger? (they must work because its been done before) if anyone knows it would be greatly appreciated if you would share your knowledge.

-Thanks

Before or after the throttle body?  Before the throttle body need to be plumbed into the compressed intake.  And one of the vacuum lines needs to go to the blow off valve.
I don't quite know what you are asking?
If it works?  You have already answered that.
What are side effects of a turbo?  
My auto doesn't quite shift right because the manifold pressure that autos rely on has been raised, so the tranny shifts later.  And when the BOV blows... it empties the air from the intake and makes the car run rich...
Like I said... I don't understand.  Please be more specific.
