Hi Steve, I almost bought the Reed manometer but I was able to get the Fieldpiece for less so I went with it.

I think you have a point. My current 5.3 reading is with the car not really warmed up (idling in the garage still on the lift, temp gauge somewhat below the 180 hash mark). I’ll make a run in it as soon as the weather clears and measure it when the car is really at true operating temp (like I do for camshaft devs).
