ABSTRACT:
Two embodiments of compact high performance induction systems for V type engines that include pairs of plenum chambers that extend over the respective cylinder banks. First pairs of runners extend from an inlet opening in each plenum chamber to an outlet opening that communicates with the cylinder of the opposite bank. Second pairs of intake passages are provided which extend from inlet openings in the respective plenum chambers to outlet openings in the cylinders of the adjacent cylinder head. The first intake passages have portions that extend through the other plenum chambers and the second intake passages communicate with the cylinders through these intermediate portions. The intermediate portions are curved and in one embodiment the second intake passages are tangential to these curved portions and in the other embodiment they are radial to it.
