OK so I started and drove the car today. I didn't get a lot of set time, but here's what I have.
81 degrees 45% humidity Party sunny
10% propylene glycol and 90% tap water
Fan on, started car and let idle. About 3 minutes running & temp gauge went to 210*
T-stats opened and temp dropped to 170*
Heat gun showed 160* at top tank and 120* bottom tank
Temp gauge in head showed 175* at water neck and 160* at water pump.
I drove the back roads doing 20-30 and 30-40 mph for about 10 minutes and temp went to 180*
Got on the high way and drove 50-65 for only 5 minutes and temp went to 190*
Took back roads home and the temp stayed at 190*
Pulled in the driveway and let it idle to get some readings
I had 188* at top tank and 178* at bottom tank.
Head gauge showed 195* and water pump gauge showed 185*
This is definitely better than before!
I used a cheap anemometer to get some air readings. If any of you have experience with an anemometer
I'd like to know if I'm using properly and doing my calculations correctly


I'm sure Lee would be able to help with the following numbers and procedure.


The fan is a 16" puller Flex-a-lite Flex-wave #238 with 3000 advertised cfm.
It's mounted close to the bottom of the top tank.
I got a low reading of 1215 FPM and a high of 1929 FPM
I converted FPM to CFM as I found on an online calculator.
I used square inches for the fan area 16X16=256 square inches I chose this measurement, but I'm wondering if I should use the entire radiator square inches. I don't think that would be the way to go because the fan is not pulling over the entire radiator.
I came up with 2146 cfm on the low end and 3407 cfm on the high end.
This is through the radiator. Being that the advertised cfm is 3000, I doubt very much my numbers are correct.
I could also try different wind measurements
