Cotreker Posted October 31, 2023 Report Share Posted October 31, 2023 Where on the intake manifold do I find the place to tap into the vacuum for boost gauge? Where does the Pryor probe need to be installed. Does it need to welded with bung? What brands are favorites? Where to purchase? Lastly where on dash are you mounting gauges? Thanks, if this topic is already posted could not find.

Steve from SoCal Posted October 31, 2023 Report Share Posted October 31, 2023 I don't have a Volvo but, I did install a pyro and boost gauge in my truck. "Most" engines have a plug on the elbow at the head for a boost gauge. The exhaust housing on the turbo should have a plug as well? The thermocouple should be on the cold side of the turbo to prevent damage if the probe fails. If either of the locations have to be pierced a tap should be all that is needed to install the sensor. Drilling the exhaust housing after the turbine is not an issue. Drilling the intake elbow should be done with the elbow open and a rag beyond the area to keep swarf from entering the engine. Don't know the Volvo dash but, the gauges should be in an area within the normal scan of instruments. I found getting the sensor wires/tubing into the cab the most daunting part of the job. The most direct path may not be the best or even pracitical way in to the cab.

Moresmoke Posted November 12, 2023 Report Share Posted November 12, 2023 Do you have any blank spaces in the dash cluster? Might be able to add the factory gauges. Another option would be a Scan Gauge whatever they call the heavy duty version. I know for certain that engine has a manifold pressure sensor, and would think it has exhaust temp also as it is an EGR engine. Quote Link to comment Share on other sites More sharing options...
