    Idle drop while braking,backing out of driveway

    This was done at idle, booster disconnected, gauge to booster line. Let idle, then checked at 3k rpm to see. My helper is vehicle illiterate so it’s been a rough day lmfao I even smoke tested and found zero smoke pushing out anywhere. Engine also assembled by a great reputable shop in Nc...

    Idle drop while braking,backing out of driveway

    doing this in morning. And checking vac as well. Also. Running a rear setup with no parking brake. Will check in morning. Also it was tuned by a reputable shop in nc so I’m sure whatever needed to be done was done. Converter I don’t think has a play here as this is a newish issue.

    Idle drop while braking,backing out of driveway

    Also, with testing it this Way, unsafe to drive with no booster vac. How do you safely test this with foot on brake and in gear. With no vac to booster couldn’t I risk damaging diaphragm?

    Idle drop while braking,backing out of driveway

    That’s on my agenda when I wake up. 12 hr shifts suck. Plus gives the neighborhood some time to wake up haha now assuming the idle dip doesn’t happen while clamped off I could probably assume it is In fact booster /vacuum related ?
