    RS2 - Normal Vacuum?

    I've tried searchin for this info, but I can't seem to find it.

    Does anyone know how much vacuum is normal on a 20VT Engine at idle? I'm seeing about -0,5 bar at idle with the engine warmed up, and about -0,75 to -0,80 bar when I'm rolling in gear.

    I believe that the gauge usually is maxed out when rolling in gear, but I'm not sure.

          Thanks for the replies! Having extra gauges is nice, but sometimes they mess with your head!
