Thread: Terminator X with Dual Plenum intake manifold.

  1. #1

    Default Terminator X with Dual Plenum intake manifold.

    I have Holleys dual plenum intake manifold and running two 102 mm cable throttle bodies on it. Would the Terminator X work with it, and what would I need if it does? It's a stock 5.3L LSx besides the intake manifold.

    Your issue will be the IAC. Since there is no common plenum, it would be hard to install an IAC. Each TB has it's own IAC and there is no way to control them both. You can maybe build a common plenum between two sides and mount the IAC there.

    This wouldn't be an issue with dual DBW TBs, since there is no separate IACs, but the Terminator X Max only supports a single DBW TB. For dual, you will need the Dominator.

    Also, those 102mm TBs will leak a lot air with the throttle blades closed, so you may have a hard time getting it to idle down, especially on a stock 5.3L. I have dual 87mm DBW TBs on top of a custom High Ram, and getting the idle dialed in was tricky, but it's rock solid now. Andrew

    What if I were to fab up a Y-pipe to connect to both plenums with a flange for only 1 DBC throttle body then I'd eliminate the complication of trying to get the two throttle bodies to run in sink and still keep the coolness of the dual plenum look. This is what it's in: Attachment 8514 Attachment 8515

    That might work. No pictures showing up. Andrew
