Supercharger outlet resonator

A supercharger assembly comprising:

• a supercharger, wherein the supercharger comprises:
• a housing, the housing comprising:
• an axial inlet;
• a radial outlet;
• a rotor bore connected between the axial inlet and the radial outlet;
• and
• at least one pair of backflow ports adjacent one of the axial inlet or the radial outlet, the at least one pair of backflow ports fluidly connected to the rotor bore;
• a supercharger outlet resonator adjoined to the supercharger adjacent the radial outlet, the supercharger outlet resonator comprising:
• a housing;
• a first surface comprising a first opening and a housing axis bisecting the first opening, the first opening coupled to the outlet;
• a second surface comprising a second opening, the second surface located parallel to the first surface;
• a channel perpendicular to the housing axis and connecting the first opening to the second opening, the channel comprising at least one sidewall;
• an envelope fluidly separated from the channel by the at least one sidewall, the envelope at least partially surrounding the channel, the envelope extending from the first surface to the second surface, the envelope comprising:
• a third opening;
• and
• at least one second sidewall;
• and
• a noise-reducing material located on the housing.
