Turbo boost gauge take off connection

[bigalw35]

Hi, knowledgable peeps, I have a 2001 Mercedes B680 2.1cc and would like to connect a turbo boost gauge, where is the connection on the turbo ?? Ideas please

An alternative aproach would to use the obd2 port but 2001 may be too early.

Anywhere between the turbo and inlet manifold.

Fitted mine to the top hose of the inter cooler, been working well for 10 years, aluminium barbed fitting and a bit of hose is all that’s needed,

Many thanks for replying, so, is it a vacuum gauge or a pressure gauge

It is a pressure gauge. Although a normally aspirated engine inlet manifold would have a negative pressure, a turbo charged engine inlet manifold will have a positive pressure. You will need a gauge that will accurately read up to about 5psi. A Gauge that has a scale of say 30psi will not give you a meaningful reading. Also you will need to find out what the turbo boost pressure is supposed to be, otherwise your readings will not mean anything.
I use a long connection pipe, to reach into the passenger compartment, this enables readings to be taken whilst driving.
