recirc question/theory

Hi guys. With the standard recircs being plumbed in down the front, could i take the recirc pipe off the inlet and block that and effectively have an atmospheric dump valve?

Would this actually sound like a dump valve or are they not designed that way?

Has anyone done this yet?

    If your talking about using the standard recirc as an atmospheric dump valve then no it will not work the standard recircs are designed to be wide open at idle when the vacuum in the intake is high and this is what acts on the recirc actuator diaphram, the air leak caused by this will cause the engine to stall at idle, only piston type dump valves will work on a zed and only worth fItting to manuals.
