This sounds similiar to a device that Smokey Yunich (sp?) used in an
article about how he got 40% increase in hp & 40-50mpg from ANY engine
(thats right - a retro-fit) just by using a similiar trick in the intake
stream.  It was a three-stage intake setup used to prepare (by heating &
homogenizing) the mixture for a more optimal combustion.  The carb was
relocated over by the fender and the air/fuel mixture was first heated
using the coolant then by exhaust gas and finally mixed(??) using a
turbo-like device that he called a homogenizer.  It was like a turbo
(being exhaust gas driven) but didn't produce much pressure.  Instead,
he said that it acted as a 'one-way check valve' of sorts.  The engine
seemed to be aspirating itself due to a/f mixture expanding against the
engine on one side and the 'check valve' on the other while in the final
stage.  

This is just the kind of effect that you mention - slight boost at all
times.  Care to elaborate on the 1000cfm fan thing?  How much juice does
it requre?
