Take a look at just about any booster on the firewall of a GM car. There's a small 90 degree plastic fitting (check valve) plugged into a rubber grommet. its purpose is to trap vacuum in the booster chamber to give ONE power-assisted brake application in case of a sudden engine stall. Adding a reservoir simply stores vacuum while it's high (above idle RPM) and makes it available when the rumpy cam you installed during your stupid attack is killing the vacuum at idle. The grommets and the check valves are available at any parts store- - - -even the low end places like Auto Zombie. Just drill or machine a hole in the end cap of your home-built PCV vacuum canister, put an output fitting somewhere, plug everything in, and run a line to your booster. This ain't rocket surgery for anyone with a few brain cells to rub together!
