Radiator Fan Test Data

[Bitsyncmaster]

I ran a baseline test with my new test setup today. Takes about 3 hours of work so don't expect the same test with Toby's fans until next weekend.

I'm doing all this just because I find it interesting learning this new stuff. So some of you other engineers may find it interesting. I should be able to compute the CFM rating of the OEM fan with this data. If any of you want to do the calculations pleas do. I took three air speed readings. I plan to compute the fan area in three areas each occupying 1/3 of the fan blade length.

The OEM fan motor gets quite hot running 14 volts. I would not expect it would ever get 14 volts with it's high current draw and voltage drops of the car wiring.
