Rarlyl8... thank you for your response. You are quite prolific in your contributions to this board and I always enjoy your write ups.

So the C2T has no large plenun for the BOV but rather has a stand alone that fits into the long neck intercooler ( I am assuming that this would be the most appropriate location for it ..ahead of the throttle/intake maniifold. So Kokeln or a newer Porsche intercooler/BOV assembly could be substituted... Where does the pressure switch get relocated to?..

A 1 bar spring in the waste gate as you say could affect the tolerances on the Boost pressure switch. Where would one get a pressure switch that would negate this and what spec would you say would be appropriate --- 1.2 to 1.3 maybe?

Lastly the BOV...so the huge spring loaded ram in the plenum....I am trying to understand the flow here... the BOV plenum fits between the throttle/intake mainfold and the neck of the intercooler as well as sits in the path of the air flow which exits the CIS box and feeds the input side of the turbo.. so when the throttle plate is closed..deceleration.. compressed air being pushed out the intercooler neck circulates in the plenum and the BOV opens up to create a loop... intake air out of the CIS box through the turbo through the intercooler ( throttle plate is closed) exit left through the BOV and back into the input side of the turbo....

The BOV is normally closed under no load ( air circulates cis through bov plenum to throttle/intake manifold) and when high engine vacum pulls the plunger/spring open the air is routed through the turbo/intercooler route to the throttle/intake manifold... do I have this right?

Thanks....
