Looks like your getting there now. For efi intake questions, ill give you some insight on the difference. Dual plane would work but limit rpms before its rated rpm window n/a. It would also work up to a certain power output before restricting the air and heating it even more. The reasoning for the single plane is equaling pulses to a center point in the intake. It does not create a restriction under pressure due to its open plenum. This alone stops power losses for the majority of the people using forced induction. Also in a boosted application the single plane does not adversely affect low rpm driving as it would in n/a form. Due in large part the comp wheel adding air to the intake charge even not under pressure conditions. Now not all engines are created equal even when using identical parts side by side. So there are those who have better power out of a dual plane intake when used under boost. However if its for a great amount of power and rpms a dual plane is simply stupid to use. as it has distributing problems that are equal(vacumn) in n/a form, but unequal when pressurized do to directional flow in the runners that are inconsistent per cylinder. It will cause tunning inconsistency and possible damages to a pressurized engine. My suggestion is <500hp either will work fine. >500hp don't take the chance on it. If there was not any difference. i think a dual plane would be most used due to the additional broad torque curve it could provide to make a turbo car even more dominating.

According to some this is probably bad tech. I Can't teach experience, but can share solid information on this subject.
