An induction system for a supercharged internal V-type combustion engine includes a monolithic continuous unitary casting housing a supercharger with a rotor and gear assembly operative to discharge pressurized air to a common bounding receiving plenum, through a first slidably-removable intercooler providing a first cooling, and then to a pair of second side intercoolers providing a second cooling within the bounded plenum and in fluid communication therewith. First and second intercoolers are secured within the monolithic housing. The monolithic housing provides a robust and stable housing of light weight and allows an exterior air cooling as well. Side walls of the supercharger are separate from and are spaced from air intake runners of a cylinder block. Air in the plenum is additionally cooled by convective surface cooling while being guided in an appropriate direction. The intercoolers are plumbed in parallel allowing for enhanced temperature management of the air flow in combination with the convective cooling. The monolithic housing includes rib elements for sound attenuation and strength while minimizing weight. This arrangement allows for enhanced cooling, and simplifies manufacture and service. 1. An induction assembly for a supercharged internal combustion engine of a vehicle , said induction assembly comprising:a monolithic continuous unitary housing member;said monolithic housing member continuously bounding a bounded super charger rotor portal, a super charger access portal, a first central intercooler portal, and opposed second and third intercooler portals;said monolithic housing member forming a continuous bounded air distribution plenum in a flow communication from said super charger rotor portal through said super charger access portal into said first central intercooler portal and to each said second and third intercooler portal;a super charger having a rotor assembly operative to produced a pressurized air through said super charger access ...
