| for a fun speedy revving and peppy ride, I don't think the need for dual intakes is needed until you start playing around with displacement. I am working a high horsepower NA engine for the project track car. The goal for that car is a 13:1 compression with a overbore to 89 or 90 mm. The heads will have a full work over and of course we work some magic on the upper intake and throttle bodies. I think at that point the need for a dual MAF/Dual Intake might prove beneficial but for 90% of the NA builds I have seen, the dual just hasn't proven beneficial. But....I would love to proven wrong. :) If you are going to do it, I would say split the signal with the Selin as it's a great breakthrough in simplicity for that.
