Abstract
The present invention relates to a modified intake manifold having short runner valves in the manifold tuning valve. Anti-chatter devices are disclosed for reducing shaft chatter without placing friction on the shafts. A lost motion linkage is used to ensure closure of the short runner valves. Radiused seating surfaces are used for seating of the manifold tuning valve.
