I use AutoMeter Gauges in my car. Oil pressure on the left with the needle pointed at the tach in the middle of the cluster at 60 psi. Water temp on the right with the needle pointed at the tach at 190 degrees. That way when I check the tach, both needles are flat and pointed inwards and I don't have to read those numbers, I just automatically know that the systems are ok. I sit so low in the car that I can barely see over the dash and I can't see the hood at all therefore my main gauges are in my line of sight with the road so I can stay focussed on the track. My oil temp gauge is in the center console by my switch panel. If the water temp is off base I can easily check the oil temp by looking to the right. My water temp pich up comes off the back of the water pump. Oil pressure pick up is just below the oil filter area on the block and oil temp at the filter. Only use mechanical gauges. Never electric gauges. Hope this helps.
