Dont call me an arsewipe sweede Now i look again, you half right n half wrong...

The diagram shows, i think, that a diverter valve opens to pass air past the s/c once the turbo is blowing hard for no restiction, but thats not really what you said in the first place is it

And the diagram shows the DV being routed back into the pipes, but look at the REAL RACE CAR in the pics, that DV is vented to atmo so
