I love the looks of the NEW Needswings manifolds. But no matter how I write it up it still comes out the same, No Extra Power.
If I am wrong please chime in but please think first.
Blower = same amount of CFM
Larger pipes and manifolds = < LBS Pressure and < CFM @ initial WOT
Intakes on heads are = to factory spec therefore = amount of CFM
All I can find as a positive is one will experiance slower kick in the butt dyno until system is at a full pressure which at that point will be equal to the original manifold power.
Isn't it so, that until the intake on the heads themselves are inlarged to and at the same ratio as the New manifolds tubes, due to the increased volume they can only cause a miniscule stall?

You seem to think pressure is related to volume it's not. When you use a compressor with the air attachment you flow high pressure but not volume. Needswings and 240 manifolds both show hp/tq gains which obviously show the heads are capable on injesting more air then the stock setup. So my first responce to you answered the question. You may register a high boost reading at the y pipe but the stock manifolds aren't flowing enough cfm once the intake valves open to fully fill the cylinders. Don't know what else to tell ya.
