Abstract: A forced air induction system (10) constructed in accordance with the principles of a preferred embodiment of the present invention and configured for supplying compressed induction fluid to an internal combustion engine (E) for powering a vehicle (V) is disclosed. The illustrated forced air induction system (10) broadly includes a blower (12) for compressing induction fluid for the engine (E) and an improved carburetor hat (14) in communication with the blower (12) for delivering the compressed induction fluid to the carburetor (C). The illustrated blower (12) is a centrifugal supercharger. The illustrated carburetor hat (14) defines a neck section (26), a throat section (28), and an internal chamber (30) disposed between the neck and throat sections (26,28).

Abstract: An air induction system (10) for use with an internal combustion engine (E) including an intake is disclosed. The system (10) includes a supercharger (12) and a valve assembly. The valve assembly comprises a valve (14) and a valve control mechanism (16). The supercharger (12) receives air through a supply opening (18), pressurizes it, and discharges it through an exhaust opening (20). The valve (14) is in communication with the supply opening (18) to control air supply thereto. The control mechanism (16) is coupled to the valve (14) and causes it to vary the air supply to the opening (18) in response to air pressure conditions downstream from the supercharger (12). In one embodiment, the control mechanism (16) varies the air supply responsive to air pressure in the intake in order to both throttle the supercharger (12) as well as substantially eliminate undesirable surge conditions therein.

Alternately, the control mechanism (118) varies the air supply responsive to air pressure in the inlet (110) of a turbocharger (106) to provide supercharged air thereto at a substantially constant pressure.
