I wait for a minimum oil temp of 120F before going to takeoff power setting.

The RV-8 cowl was off due to changing the oil, so I gave it a pretty good inspection, reassembled it and started it up.
I was planning to do a tethered trial at take off power, but the weather was clear and cold with low overcast and no wind, so I taxied about while waiting for the engine to warm up.
It never warmed up. The oil temp came up to about 156F, but the water temp came up to 128F while idling or slow taxiing. I did 4 aborted take off, the water temp rose to about 138F.
I have heard that this is not warm enough for full power. I did accelerate to 4850 RPM (2200+ prop RPM) before I let off the brakes and concentrated on rolling down the runway, lifting the tail and throttling back @ about 45 MPH.
I don't have a thermostat in it right now, the one try with a thermostat ended in an overheat shut down before damage. maybe I didn't have all the air pockets burped out. So I might have removed it prematurely.
What does the group say about warm up before take off, and about using a thermostat?
