Gauge Explanation

[blue_xr6]

I just got my 3 gauges (oil press, oil temp and boost) installed on my T. Since I don't know much about these things, just need someone to explain what are these gauges used for. From the name, I know the oil pressure gauge measure the oil pressure, the boost gauge measure the boost... but can someone tell me more about those numbers on each gauge and which level indicates a good condition on my car and which level tell me that my car need intention. My gauges are ozegauges.

Just say if my car is running at 8 psi (0.55 bar), the needle should point at 0.55 on the gauge is that correct? How about those numbers below the zero on the boost gauge, what are they used for?

Any helps are greatly appreciated.

mate anything below zero is vacum and this is what the guage will run at untill the turbo starts to spool up and make boost (between 2200 and 3000rpm depending on car etc..) if you are running 8 psi it wont read that unless you are at full boost under acceleration

hope this helps

Thank you for your information on boost. How about the oil press and oil temp? What should be the normal reading on the gauge?

My ozeguage oil pressure sits at about 4 bar when warm and highway cruising. It sits higher when cold. Drops down to two when idling.
