Now for the numbers.
Electrical - on low speed the fan draws 16.5 amps. On high speed the fan draws 22.5 amp, numbers bounced around some so it's a middle number.
Once the engine hit 210 I jumpered out the switch and turned the low speed fan on. Once the low speed fan cooled as much as it could, probably after 10 minutes, I engaged the high speed to see how much farther down it would go. Ambient was 101 degrees when I measure the numbers with my Ratek IR gun. 185 degree (rated at fully open) thermostat.
Low speed got the temps down to 167, high speed got it to 165 and that I believe is when the thermostat was fully shut.
I did capture airflow numbers. Mechanical was done at idle speed, which is when airflow is at it's least. No shroud in the stock setup, small diameter 4 bladed solid mount fan.
One final set of numbers, it got to 106 yesterday by the time I came in, today it got to 104. I lost 6 lbs, despite trying to stay hydrated. Only 50 more to go, lol.

Took the old Cambridge out on the highway today, only the second time I ever did that. The first time I did it, I got on the highway got it up to 65 and got right off the highway, too squirrelly for me. Since then I rebuilt the front end, new king pins, added some good gas charged shocks in the front, added Aerostar springs, one coil cut. Much less floaty in the city now. DIY alignment.
Took it out on the highway today with my son, got up to 70 mph at one point. She handles the highway well now. Slight drift right if I let go of the wheel. Not sure if it's alignment or road crown. I guess I'll spring for a set of turn plates and double check the alignment. My $1.25 store converted pizza plates ain't cutting it, lol.
Still to do, adding gas charged shocks to the rear. Maybe find a bigger sway bar for the front. Some where I read someone used a Jeep bar, but as is typical no details to speak of.
