Abstract
A number of embodiments of compact high efficiency induction systems for an internal combustion engine. In each embodiment, the induction system includes a first pipe section that extends from the respective intake passage of the engine and which terminates in a downwardly turned right angle section. A U shaped pipe section is interconnected at one end to this right angle section and its other end is served by a plenum chamber that is integrally formed with the first pipe section. In some embodiments, the plenum chamber lies at least in part over the first pipe section and in other embodiments it is forwardly of it. In some embodiments, the U shaped pipe section is detachably connected to the plenum chamber, first pipe section assembly so as to permit attachment of different length sections for tuning for different engines.
