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.
