Yes, like I said, airflow.

My stock turbo evo 8 flowed 42lb's of airflow through the motor at 27psi. The 20g I put on afterwards flowed 46lb's of airflow at 26.5psi. Which do you think was more stressful on the motor?

Larger volume of air/fuel along with a smooth air will generally produce more power. Only things that will restrict it will be intake CFM. This can be exacerbated by to small a throttle body/s, or reduced positive intake pressure.

The idea here is to speed up the flow of Air/Fuel and balance the charge to each cylinder without disrupting it in the process. I could only show you on a flow bench, as a practical application.

FI engines are not as dependant obviously as an NA engine, although they can benefit additional the additional flow characteristics. I could go on about the size of plenums, tubing bends and lengths, deck heights, circumferences etc. as it would only confuse some. Believe me, it's a bit more complicated then welding some stainless tubing and air boxes togather to design a horsepower making intake manifold.

There were some pictures GTM posted in the other forum several months ago. It looks like cast:
