Spuggy - very helpful. Thanks. looks like a critical piece of kit. Just checked mine. It is still working.
If I understand it right, this piece of gear bypasses the boost pressure in the IC etc, either to waste, or in this case into the turbo intake side. It does this when the throttle plate shuts and the vacuum on the underside of the plate sucks the valve open, allowing the dump of pressure?
Is this so the turbo doesn't stall since no air is being sucked thru while the butterfly is shut?
