Vacuum line, BOV+boost gauge
Craigorypeck - 18/10/11 at 09:58 PM

Wheres best to take a boost gauge reading from?
Each cylinder has a separate runner, one currently has the servo tapped in and the BOV has a reference from another.
Can the bov line just run a t piece for the gauge or should I steer clear and tap into another unused runner....?

Cheers!

Normally I would "T" them all together to get them equalized.

So best run a reservoir from each separate runner then have lines for bov and boost gauge from there?

Its a good idea to run all the vacuum connections into a small plenum so they all equalise then take your sensor connections from there too. Makes for a more stable and accurate reading.

Won't be much vacuum if its a blown system?

I havent seen many blown systems that doesnt show vacuum 98 % of the time.
For how long do you run 50 % throttle or more?

Dont make a plenum - Just a connection between the 4-5-6-8-10-12 cylinders.
