what the.... I thought the B18c1 butterflies flew open at high speeds to supply big fat air to the plenums and intake ports. Now I'm told they do the opposite? They are open until the high end and then shut close? Right when short fat quick lines of air are needed? Like the Type R manifold that has the short fat plenums.
Can someone explain? I have been lightly massaging the upper roots in the intake chamber but if the fat tubes are going to be cut off at high RPM's why not just extract them? What the... why are they .....why I otta....why I... POW ZOOM TO THE MOON, ALICE!!!!!!
