Default Vacuum Block Routing

I have a general idea of how I am supposed to run the lines but some things are still unclear like pre TB or post TB connection points.

I have dual 44mm gates, BOV, AMS 500 V2 boost controller and boost gauge. Anyone wanna draw me up a diagram to show how things should be "properly routed"?

Here is the vacuum block I am using:

Are you splicing this into the brake booster line?

The WG and boost controller will be tied together, you are running C02 right?



Otherwise, I would use a port direct on intake for BOV, and run all other stuff off your vac block. You can search for Blackbirdws6's setup for mounting the vac block.

No C02 just yet? I'll see how the car leaves on 8lbs (which should give me a max of 16lbs) and then change the spring to the 12lbs(which should give me a max of 24lbs) and try to run at least 20lbs of boost. Then I'd get a C02 setup

Slightly iffy pic


But, passenger side has one line running to the FPR. Other ports plugged.

Drive side has the one port on intake dedicated to BOV, then the brake line fitting runs to feed the vac block. That has all your sensors and other feeds needed for boost/vac etc. This was all done with AN fittings and what not for easy removal.
