    Yes, it drew through the carburetor then pushed into another part of the adapter and into the engine. It was a early 'Turbo-sonic' unit and it worked pretty well. Had a 7 lb spring in the wastegate.

    PS. Remembering, as it has been a long time ago, the adapter the carb sat on had a series of 4 floating steel discs in it. Under normal running the fuel/air would enter the engine through these ports. Under boost, the positive pressure would close the discs and the fuel/air would now be pulled into the turbo and sent to the engine below the adapter. It sounds sort of funky but it did work and there was no noticeable lag as it went from no boost to boost.

    Did it have anything to richen the mixture when it was on boost or did it just rely on airflow through the carb?

    Keep in mind this was a bazillion years ago I have have cerebral cobwebs now. It was a Rochester Quadrajet and the secondary metering rods and jets were modified to dump extra fuel when they opened..when the motor was under boost. At least that's how I remember it. This was in the mid to late 70's and things were still somewhat in their early stages, turbo wise..at least in my area.

    So, nothing special to richen the mixture, only tweaking in the carburetor.
