I run all of my dyno pulls with 180 degree water temp these days. I used to try and run cooler but eventually just decided it was easier to run everything at 180. I usually try to get the oil to 180 also but it tends to vary more. Sometimes the first pull is at 150 oil temp and then after a few back to back pulls it will get up into the 200 range.

Glad to hear it ran good. 28 pulls in a day is a lot of work, especially if you are swapping parts and then trying to get the engine pulled down and ready for the road.
