Random thought on Stillen Gen 3 and VVEL

I was looking at different dyno's of the JWT intakes vs the Stillen Gen 3 long tubes, and began to wonder why the huge difference in power. Yes the usual lower IAT thoughts come to mind, allowing for the ECU to keep/add timing, but that can't be it alone. Then I saw that video explaining some of the VVEL technology, and a thought came to me. Since throttling is happening at the point of the intake valves, and not at the TB during post startup operation, Tubes are essentially acting as an extension of the upper intake plenum. The longer tubes add additional volume, but also and more importantly increase air velocity. Both these factors are important in adding torque in NA motors. Basically the upper plenum has had several liters of volume added, and it's runners lengthened by 3 feet. Just a random opinion I thought I'd share.
