Mechanical Boost Gauge Hook Up

Where is the best place to hook up a mechanical boost gauge and what type material for the tubing?

Best place - intake manifold
Best material - S/S braided line

Or the brake booster, it's a bit closer.

Actually it depends on what you want to read.
If all you are concerned about is the boost level seen by the engine heads then plumb the line into the intake manifold after the throttle.
If you want to also see if spikes exist during closed throttle events then plumb the line before the throttle.
If you are interested in the shortest path to run a line then plumb it into the brake vac system.
The stock location for a 930 is plumbed into the BOV housing - before the throttle. If you use a tattle tale gauge plumbed into the stock location it will record boost spikes.

As for line material, if you desire the least expensive material use plastic tubing. If you desire the most robust use S/S braided line.

Before throttle: no vacuum but you see boost peaks in case BOV goes off-line.

After throttle: you get vacuum reading but no boost peaks.


Your gauge doesn't register vacuum so I suggest connecting it somewhere on the intercooler, before throttle. Hose material is not critical, there is no flow trough the hose. Ordinarry rubber line works OK.

I bought one from Hollywood speedo and it came with the "T" and hose kit for the brake booster. It is a boosy only gage and works great. Since the brake booster is in the front trunk area and never sees any sort of abuse, you don't need SS hose. I used the same hose that vacuum lines use.
