Think of that area as like a blow off valve. When less boost is needed this is open and the boost leaves the intake manifold. When you want more boost the valve closes and pressure goes up.

Ok, and when this valve opens to release the extra boost, where is that extra being dumped to? Exhaust? I remember seeing a line running from around the BCS area to the exhaust manifold i believe.
Also, does the M62/90 have any form of cooling system? Such as a water jacket transfer from the intake?
What are the two upper holes used for where the throttle body connects?
And the single one on the left?
Sorry for the multitude of questions, I really want to get the grasp of how this SC works.
Thanks again!

The boost reenters the system between the throttle body and the rotors to be reused.
The two hole above the intake is the cooling jacket. A small amount of coolant goes threw the throttle body to warm it up.
I seem to remember there was a write up in tech info about superchargers and how they operate. might make for good reading.

Awesome, just read that article, i understand the theory of superchargers, I just wanted to learn more about the M62/M90.
Final question for you sir, whats that port to the left of where the throttle body connects?
The return line for coolant?

The BCS is operated by vacuum with a vacuum solenoid. The solenoid needs to get vacuum, as does other components; and a vacuum tree occupies the area I believe you are talking about.
