Building a vacuum reservoir?

[Cloud]

Do you think there is a cost effective way to use autozone/home depot parts to make a vacuum tank to actuate a cyclone manifold? I assume all I would need is a one way check valve and a reservoir that had correct sized hose inlets and outlets. The cheapest I can find them from a dealer is still over $30 and I just got laid off so I can't really afford to nickel and dime myself with all my little projects anymore... but I really want to make the cyclone work before I stop.

all you have to do is find a vacuum chamber from a montero. I am pretty sure you could buy them new, and they are same as a stock cyclone pretty much. I'll have to find out what year montero.

Yeah I know, and normally I would just buy it but I am in between jobs and looking to scrape for rent and such. If I can build a boost controller for $4 at home depot instead of spending money I figure there are other parts I can do this with.

What I did was use the Nitrous controls in DSM Link to control the fule pressure selenoid which in turn will controll the actuator for the runners.
What I did was hook a vacuum line from the manifold to a check valve (I used a PCV valve which is one way), then from that to the fuel pressure selenoid (which is normally open). From the selenoid to the actuator on the cyclone (which looks like a little wastegate actuator.
By doing this, you will create a vacuum all the way through to the actuator while the car is running which will cause the runners to close (they are normally open). Once I hit the pre determined settings in DSM Link it actuates the fuel pressure selenoid cutting off the vacuum and allowing the runners on the Cyclone to open.
Does that make sense? Basically all you need is a pcv valve, fuel pressure selenoid, nad some way to controll it (which is what the canister would normally do).

After reviewing the diagrams and operation there really isn't any need for a reservoir, it isn't supplying vacuum to a non-actuated source so it doesn't need any volume at all. It's just a hold and release mechanism so a check valve should do just fine. Thanks wazzelby.

No problem! Let me know how it works out for you.
