Mike,
To help answerone of your questions, or At least one thing to consider is the venturi effect. Sometimes too much flow is well, too much. Allvolume and no air speed can hurt too.
Back in the days of carburetors, "choking" a fully adjustable carb w/a venturi could bea good thing, rather than bad.
i.e. The stock AM setup for a dual DCOEWeber setup for a BMW 2002 were dual 45mmcarbs w/a 42mm venturi. But w/o a highly modified racing engine behind them they would turn it into a gas guzzling DOG!! For a streetable engine, it was actually better to go w/40's or 42's and choke down to 36-38mm.
