To digress slightly -- a 1000 cfm Rotron cooling fan,
what benefits could one expect from putting something
like that in the intake flow ???  It draws little juice
and would insure a _slight_ positive pressure flow
under all conditions -- and esp at low vehicle speeds.

Just a thought I've been playing with.  Seems it
might make some slight but noticeable improvement
on the normally aspirated engine ???
