Any progress on this? Just got my 2000 Bluebird All American and was wondering the same thing. I don't have a pic to post, but indeed under there is just the intake. It is not vented to the outside that I can see, other than by the engine compartment doors.
If one were to re-locate the intake further down into the engine compartment, does that affect performance at all? Does that intake need to be higher than the engine in order to draw air?
