Thanks for illustration ryan
Now from looking at that, and with me not having VIC's butterflies/shutter valves, I would be getting double the air?

Down low yes. Up high no.

Also, down low the velocity of the air would be lower because you do not have the VICS butterflies (closed). This might hurt your bottom end a little bit

No it gives the charge correct velocity to suck itself in sort of and propagate through pipes with minimal losses. For each speed of air there is a correct diameter/length combination for maximum efficiency. This. Adresses the issue sort off

Howd you get fuel from that diagram?
It shows what happens at specific points in the rpm range. How the runner length changes to suit the RPM band. At higher rpms the reflections should be shorter/fewer.

another thing to remember is that this only works on NA applications as on FI runner lenght doesnt affect it as much. so in the high RPM range when the buttrfly is opn the suction of the engine will more likely suck through the shortest path IE the shorter runner and not that much through the longer one

Here is a dyno graph of my engine open vs closed with the 1.8 ecu.
