I have been watching a lot of Dyno testing of different combinations lately and there's a guy, his name is Richard Holdener. Check him out on YouTube. Very sharp guy and makes some very interesting observations and explanations of things. He has done a ton of tests comparing single to dual plane, shirt runner and long runner intakes and it almost always leans toward the long runner or dual planes, anywhere under 6k. Not just small displacement street motors eithi. His point on this is regardless of displacement, boost or no boost, the intakes generally are more rpm dependant than anything else. And he backs this up with Dyno pulls. And we're not talking 5 ft lbs torque. It's often like 30-50 ft lbs for large stretches of the power curve. That's a big reason why I've been seriously pondering this in the first place.
