Haven't read it yet but looks interesting

 

didnt IvoryGT do something like that?

 

I've read that before and I love scientific articles like that. Actual applied science. How novel.

Reading stuff like that always makes we wonder about that the resonators on the 1st gen G intake pipe. Are they Hemholtz units or not and if so, why doesn't the Z have them? Is there something special about the Z airbox that the G airbox doesn't have therefore needs the resonators? The VQ Maximas have similiar inline resonators and they have been shown on the dyno that they are indeed Hemholtz resonators and improve midrange power by up to 8whp.

 

From my time with the Z oem airbox (v-stack conversion):

1) The G has a way bigger resonator on the tube AND a larger resonator below the airbox.

2) The Z's airbox has a much smaller one.

It's my opinion that the resonance as far as it pertains to hp/torque lie in the plenum itself and doesn't extend beyond the TB.

 

For those interested here is a desertation of design of system:
