|  | | | Porsche 924S/944/968 Fuel Injection - Page 4 | Turbo Cut-Off Valve | | A diverter valve, also referred to as a "pop off valve", "blow off valve", "boost re-circulation valve", "air/boost bypass valve" is designed to re-circulate the boost pressure that gets built up in the intake manifold in between shifts. The valve at idle (under vacuum) will remain open allowing the air to circulate freely through the intake to the turbo (s) fresh air side. As soon as the throttle is cracked, ie: the accelerator pedal is moved, the valve will be forced shut stopping the re-circulation of intake air to the turbos and allowing all the boost pressure to enter the motor. The OEM valve is what is commonly known as a diaphragm valve. This valve has been around since the mid 80's and has always been a very problematic part that typically wears out within the first 6 months of operation.
