Yeah, I missed that one too. Found out about it after the issue went off the
newsstands.
The more suction/pressure you can have the more accuracy you will get. Check
the Superflow site. Try this to start:
http://www.superflow.com/flowbench/sf1020.html
The NASCAR teams use a very high level of test pressure. Any small changes
are soon apparent.
Also, it simply takes quite a bit of power to turn one of those Rootes type
superchargers that Eaton makes.
You can improve your heads with a vacuum cleaner level of suction, but you
can truly REFINE them with more pressure available.
