Abstract
Abstract Several embodiments of supercharged V-type engines wherein at least one plenum chamber is provided that is disposed adjacent at least one of the banks of the cylinders. A supercharger is positioned at the transmission end of the engine and is interconnected with the plenum chamber through a relatively short conduit. In some embodiments, the supercharger is driven from the transmission and in other embodiments, the supercharger is driven from the opposite end of the engine. In one embodiment, there are a pair of plenum chambers, each disposed above a respective cylinder bank.
