And that difference in large part comes down to the kind of experience and knowledge that you and Mark represent. Thanks much for sharing.
The fan data is very helpful for me - I'm looking to upgrade the track day cooling on my car and I think airflow is one of the major areas for improvement. Trying to figure out the part numbers for the SRX fan, is this it?

And do you happen to have the part number for the fan controller? I'm switching over to a GM E38 controller, and am very familiar with HP tuners and the PWM fan control settings, so I think that part is straightforward ...
Again, thanks for your contributions.

SRX turbo fan part number is 25931645 as you show. PWM controller is built in to fan motor - so no separate module like Corvette fan.
Max PWM duty cycle is 90% positive polarity @ 100 Hz (need this for calibration). Size wiring & fuse appropriately - 64 AMPS peak.
First used this fan on Red Devil and dropped coolant and oil temps ~10F just by changing to this fan from 400W Corvette fan.
