You're right about the diagram...marconi seems to indicate that its possible to get to the intake manifold checkvalve without taking the valve cover off...i'll check that Saturday when I actually get to work on it a bit..

agreed on the amount of vacuum, but a company could easily test this and be able to sell a very nice system. max manifold measurement and some calculations based on the restrictor would be a good start.
