If I feed the plenum flap from the resonance flap, it should open at 3k rpm, thus not restricting airflow at low rpm. The downside is that the resonance flap closes at >5k rpm and so at high rpm I may restrict airflow since the intake manifold will be cut into two separate intakes. My hope is that this will cause a supercharging effect at the heads (crossing my fingers), or wreak havoc on the intake tuning lol.
This is the extent of what I think I know. Does it make sense at all?
