Pat 12 gets a nose job

Hi Tony

Your giving me some interesting things to think about with this which is making it into both an interesting test but a quest for more information. I'm rethinking my testing logic and data collection methods. One thing for sure next test will set the Go-Pro Camera to capture the engine instrument panel through the whole test. Need to move it closer to the instrument panel this next time, so the gauges are easy to read.

At the end of your post you said " It would be interesting to set one up in a perspex tube instead of the housing, so it could be seen operating. It would also be interesting to have a delta gauge on the dashboard, I'm not sure what earthly use it would be but the same could be said of vacuum gauges"

Your comment about being able to see the thermostat in a prespex tube how about thisl

Here is their web site https://coolviewthermostat.com/ not sure I want to spend that much for a single test but it would provide an interesting diagnostic tool. I just check and they have one that fits 216 https://coolviewthermostat.com/products/chevy-products/ and they have ones that fit the Ford Flat Head.

Here is the first round of data collection for this test

I'm going to do one more engine flush on the radiator tomorrow then do another round of testing.

Bob, your thoughts on cleaning are running along with mine. I did back flush the radiator with it upside down but surely did not reach the flow rates my flow test (on the 261 at 1000RPM) showed of 20GPM. Had thought about mounting the radiator upside down running the engine but with no way of catching any trash that might come out decided that might be counter productive.

One of the things that running the engine from cold to full hot showed was the value of the coolant recovery tank over a Half Gallon of water goes out into the tank and is drawn back in as the engine cools.

Cheers Phil

PS In the 1990s worked on a couple of large Co-Gen setups for hospitals we were using 545 Cat engines which put out a lot of heat at full power, the system was recovering the heat from both exhaust and from the cooling systems and using the heat to heat the hospitals. As owners rep on the project part of my role was to make the various engineers and suppliers explain how the system and components worked. If they could not explain it they generally did really understand it themselves.
