Abstract:
A secondary wide open induction apparatus comprising:an engine intake manifold having a primary intake and at least one secondary intake located downstream of the primary intake; a primary throttle body connected to the primary intake; a secondary throttle body connected to each secondary intake, each secondary throttle body having an inlet, a channel, an outlet, and a normally-closed throttle plate disposed within the channel; a throttle control for controlling the secondary throttle body, the throttle control being connected to the secondary throttle body; a throttle position sensor for detecting the throttle position of the primary throttle body; an engine controller receiving a throttle position signal from the throttle position sensor and transmitting a control signal to the throttle control to effect opening of the normally-close throttle plate in response to the magnitude of the throttle position signal exceeding a predetermined value; and a switch in electrical communication with the engine controller, with the engine controller interrupting the transmission of the control signal in response to the switch being in an off position.
