I don't know if you would need significantly more air with dual carbs. I would think that the amount of air needed by an engine is a function of displacement and RPMs, not of the size or number of carbs. Larger or more carbs might let the engine breath at its full potential. Therefore, if an engine is drawing a constant amount, and it has to do so through a restrictive aircleaner (which flows at Xcfm) , it seems that the engine would have an easier time drawing such amount with two carbs and aircleaners which could flow 2Xcfm. I have no experience or knowledge in this field whatsoever, so I might be way off base.
