    Default Keep A/C after 3x Weber swap. Where Vacuum connector, Fast Idle Actuator connect?

    Hi,

    I'd like to keep factory AC even after swapping fuel injection to triple weber.
    I could not find any documentation about how to.

    Does anyone keep factory AC with triple weber with canon intake?

    Thanks,

    With the weber you may end up setting your idle to 1000rpm so it would already be relatively fast and should be able to handle the AC load.

    Tapping a runner for idle vacuum would be easy but setting up a fast idle with air for each runner would be similar but more complex as you will need some sort of controlled air device to leak just after the throttle valve. An alternate way would be to hook up some electromechanical system for opening the throttle at the linkage.


    I'd try AC w/o the controls first to see if it affects your performance and ease of driving at idle.
