I just bought a A pillar gauge pod and i am planning to install a boost/vaccum gauge on my 1985 supercharged 928. so i am standing in front of the motor and i have no idea where on the intake manifold should i attach the vaccum hose to get a correct reading???
BTW, it has a S4 intake manifold
Any ideas out there.

I take mine off the fuel regulator vaccum line.

Thats probably more convenient than the ports on the underside of the throttle body

Tim Murphy suggested that I take my vac line off or near the computer brain. That way you get a very close read to what the computer is reading. Meanwhile I had already taken off from very near the FPR, so now I've got to swap to Tim's advice.

Thanks for all the advice. I will run it to the vaccum line by the brain.
This is a great forum!!!
