Many Many years ago. I wanted to know if my radiators cooling capabilities had decreased over time. Because of deposit buildup from leaving anti-freeze in more the 3 years. So, I pulled the thermostat out. Put the coolant that I had drained out, back in. Then went for a drive. If the temps are much lower. Then I knew that the radiator was up to the task.
There are many more areas to cover on this topic of cooling the engine/trans. As to the cooling of our GMCs. And those can be covered if there's interest. In short. Buy the things that you find you need. Not the things that you think you need.

The flaw in the test you did is is if the conditions are just at or below the capacity of the cooling system, then removing the stat will cause the system temp to drop. Only because there is no lower limit set point This does not prove the ability to shed heat and prevent temp climb in severe conditions.

This isn't a real scientific test. But an indication of the ability of the radiator to transfer heat. I've done it on 4 GMCs. Drained, flushed, and filled the system. Then took it on a short highway trip. Try to do it on days above 85 degrees. Then come back to pull the 195-degree thermostat out. Refill for that same trip again. If the engine temp is anywhere around 155 degrees. I see that the radiator has good flow. If the temp is around 175 degrees, or higher. Thus, the radiator is acting as a thermostat. By the restriction to the flow of coolant/ heat. It's just an indication. Nothing more.

Isn't wait upfront a good thing with a FWD car? Sometimes, when going on
the onramp of the Autobahn, I do wish for more weight upfront, so that I
do not have to be easy on the throttle. :-)

Olly,
Our LSD helps to keep traction on both sides.
