<div class='quotetop'>QUOTE (Jazz9 @ Feb 26 2008, 10:10 PM) </div>the butterflys are open at their rest position,
they use the manifold vacuum to close in the bottom half of the rev range,
the reason i want it working is coz it's a pig to drive with it disconnected you go no where under 3,000rpm,
that and you loose a significant amount of torque without them working,
