I can't believe a venturi is this bad.

    Thanks Larry. I'll check it out.

    The first one with the venturi calculator does not appear to put out
    the data we need. What we need is pressure at p2 as a function of
    air flow
    for this calculator to work. Apparently you have to know what that
    is and plug
    it into the calculator. My browser will not run that java applet for
    some strange
    reason so perhaps somebody with IE can experiment with that for us.

    We need at least 3 input flow values 20 CFM, 100 CFM and 200 CFM.
    More would be better say every 50 CFM.

I have dealt a bunch with single port restricotrs in the fsae series. I
dont have time to run the numbers but if you call the guys at Raetech
they will straighten you out real quick. This is also a SAE guidline to
restrictor design. I dont know where it comes from in terms of purpose
but it pretty much matches most converging and diverging cones I have
seen on racing engines.

Off topic but interesting.
