Thread: 3 Bar MAP Sensors

    Default 3 Bar MAP Sensors

    Does Holley plan to or already have a 3 bar MAP sensor that will plug into the stock location on the Terminator throttle body? So far, it looks like I have to use a remote GM/Holley style 3 bar MAP sensor and either make an adapter or cut and re-wire the MAP connector, which I really hate to have to cut it up. Thanks, Dan

    No, the Terminator TBI systems are complete kits, intended for naturally aspirated applications; therefore equipped with a 1 bar MAP sensor.

    The supplied (LS1) 1 bar MAP sensor (naturally aspirated) is attached to the side of the throttle body. This location is fine for a 2 bar or higher MAP sensor, on a blow-through application; but if a Roots type blower (draw-through supercharger application) is used, you'll need to abandon the existing MAP sensor location and connect a 2 bar or higher MAP sensor hose to the bottom side of the blower (boost).

    If used on a blow-through application, find a 2 bar or higher MAP sensor (such as a Pontiac Grand Prix, GTP) that fits.
    This will be the end user's responsibility, but here's some options:

    http://www.powerandsignal.de/docs/Products/09350899.pdf (Delphi/Isuzu 2 bar MAP sensor)

    http://www.powerandsignal.com/docs/P...s/12215049.pdf (Delphi 3.3 bar MAP sensor)
    http://www.powerandsignal.com/docs/P...s/09373269.pdf (
    Delphi/Isuzu 3.3 bar MAP sensor)

    Another aspect to consider is the 250-600 horsepower rating (
    naturally aspirated).
    With forced induction, the maximum rating is 500
    horsepower due to the increased BSFC.
    The four 80 lb/hr fuel injectors won't support big power levels.
    May God's grace bless you in the Lord Jesus Christ.

    Thought I would share what I found, as this might help someone else that is looking for MAP sensors that would work in a
    blow through turbo setup, without needing to use a remote MAP sensor and having to plug the hole in the Terminator TB.

    GM MAP Sensors, true linear 0-5 volt scale:
    Delphi 2 bar - 12615136 (Various GM cars/trucks)
    Delphi 3.3 bar - 12215049 (2004 SILVERADO 6.6L DIESEL)

    These sensors are slightly different than the stock Holley one but the connector is the same and so is the hole that the sensor pushes into.
    The nipple on the sensor was also off center slightly but it was real easy to make it fit.

    To make them work I had to:
    Cut the top retaining clip off the new sensor with a pair of dikes so it will clear the underside of the air cleaner mounting flange.
    When installing the sensor, rotate it slightly counter clock wise so the screw hole in the metal clip that is used to mount it to the throttle body will line up correctly.
    Done, easy. NO modifications at all are needed to the TB or its wiring etc.

    If I'll use the Delphi 2 bar MAP sensor, what sensor type should I choose in the Holley laptop EFI software?

    You'd select "Custom 2 bar" MAP sensor (Sensors ICF), and enter the Calibration Curve values.
