Re: Ditched the "Air Maze"...
I am going to guess that with the elbow facing down the airflow is set up to turn up through the venturi. With the elbow up or sideways that is not the case. Air flow can be funny through a series of turns. That is why a generous radius is used when the lowest pressure loss is desired. CAD programs like Solidworks have options where the flow through a passage can be visualized. The flow is always surprising. For instance, with a straight inlet the flow gets restricted just past the opening. That is why horns are used on the inlet to carburetors on racing cars.
