When I'm actually "running" the car hard I'm not watching the gauges at all. So I figured let's see what most folks watch while driving. I moved the water temp up to the A pillar where I can see it easy. That one is a no brainer. What would your second most watched gauge be? My thought was with my high stall I'd like to know how hot my trans is. The only other gauge I care about it oil pressure but that just is what it is. If it falls off I'm screwed and I have no way to pull over and let it fix it self. (unlike temp, that I can fix by stopping). So I figured let oil PSI be down in the dash and H2O, Trans temp be in my direct line of sight? What do you monitor most? Remember my car is a "street car" so it is driving around. Not just rolling off the trailer.
