[V8] Intake/supercharger

[Buchholz, Steven]

... the project I was discussing on the phone involved retaining the Ford's
intercooler setup ... seems to me that approach might allow you to use the
factory lower IM.  The thing is that the engine on my bench still has the
upper and lower IM in place, so I am not sure about whether or not it would
be practical to mount the blower above the factory lower IM.  Perhaps it
would make sense to attach the blower to the *upper* IM ... it is mostly
just a plenum after all ... if that would make any sense then you could
possibly retain the Audi MAF ... and then pull the "elbow" piece that feeds
the TBs and replace it with something to accept the inlet from the
intercooler.  Funny, this almost sounds as funky as the guy wanting to drop
a carb on his car ... ;-)

As to the subject of auto adjusting ... sure, the engine will try to use the
OXS feedback mechanism on the fuel side, but there would be no compensation
in the ignition circuit.  I've got to believe that you will need to have a
way to tweak the timing based on the manifold pressure.  I guess that means
that we might be talking about tossing the factory control out the window
completely ...
