Check out this picture of a Vortech Supercharger in this Jaguar SC. It blows through the Airflow Performance Fuel injection throttle body. The funny angle is due to an airbox that is designed to allow a trap door to open should the Vortech get clogged for some reason. The trap door will allow somewhat impeaded airflow into the engine to keep it running even though the supercharger's output is blocked! I have come up with a better design which I will incorporate into my LS-1 / Vortech conversion.

And yes, you do see a standard (electronic ignition) distributor on that LS-1, actually, two of them!
