my bad i keep calling the secondaries housing type thing a diaphragm

That's strange... how could they be open all the time with high vacuum? Mine are hooked up that way and are closed at idle and open at higher throttle/rpms when the vacuum drops and gets closer to atmospheric pressure....

Is that a typo perhaps?

I remember hooking it up to the back of the intake mani and nothing happened. It wasn't a typo but it was weird. I was experimenting with making the iab's close and they just stayed open the entire time ::shrugs:: maybe u guys will have better luck cause i don't know what happened to mine there maybe the plug was clogged. I never checked to see if it was sucking in air unplugged anyways so that could've been it

Hey Zigen, are you saying to just disconnect the vacuum hose from the metal drum thing and run it straight to the back of the manifold or to run the vacuum to the IAB box and run another vacuum line from the IAB box to the back of the manifold?

Old posts are good... revitalize the current knowledge base instead of making a newer post asking the same thing...
