I have a cyclone intake manifold and I'm trying to set it up to be RPM activated by the FPRS. I found this diagram online and it seems pretty simple and I have all the parts but I'm not sure this is right, or if I'm reading this right.
Does the canister flow one way from B to A? It makes sense how I'm thinking about it, and that's with boost pressure causing the butterflies to actuate.
But if the canister flows A to B I'm not sure how the FPRS or the actuator would work. I guess I'm just confused at where the air travels in this diagram and how the FPRS shutting could make the butterflies open. From what I can tell intake is normally closed so it uses the long runners at low RPM, and air flow has to make it to the actuator to open the butterflies to the short runners. But I don't see how closing the FPRS at a set RPM can do this. Especially since I could be seeing either boost or vacuum at that RPM.
