So are we saying that only one inlet valve per cylinder is actually in operation at lower revs?
And if the butterflies are uncontrolled and flapping about when the connecting arm is off, what position do they want to assume (closed or open)? Will the airflow want to close them? Or will they want to maintain an open position?
If you were to lock the swirl shaft in the open position (assuming this is with the rose joint pulled out towards the swirl motor) then you should have both inlet valves getting air, and you shouldn't have any performance issues on acceleration? And mpg should also be OK.
Perhaps Clan could verify this?
