I bought the output pipe that has the fitting already drilled and tapped for a temperature gauge, and the T-stat is in the upper hose with the button facing the engine as close to the engine as I can get it. I drilled a couple holes in the T-stat.

I get very stable results except, there are times on cooler days going down a hill where the reading will go pretty low, but come right back up under any kind of load. I have a 160 degree and the only time it goes over that is on a hot day when even wide open, the cooling system would go over even with no T-stat in the system. With the new Brassworks radiator, it stays below 190 even on a pretty hot day. But, going back to non-extreme weather, I get real stable results with the set-up.
