Ernest,

      Some where in all those links I sent you I saw a reference that with

tight housing tolerances the VW fan would pump up to "5 psi" but I do

not no if that pressure was measured with a running VW engine sucking

up all the air or was just a static fan test to determine cfm and pressure..

 

I think that should probably have been 5"H20.
