I realize that there is probably not any kind of answer.. but thought I would check just in case.
Any idea of the CFM for an 80 series cooling fan mounted to a modified blue hub and turning at say 2500rpm would create? Or any RPM for that matter if there is an answer looking at it that way?
I am just not sure that the dual SPAL fans attached to my Ron Davis radiator are doing a great job. Before I go to the cost and work changing back to "stock" setup.. I am hoping for some ideas that might spur my interest in doing so. Seen some temps this summer with A/C running and ambients of 95º that have me raising an eyebrow. Long fairly steep grade at 40mph (all she would do) over 8 to 9 miles in full sun.. engine temp of 219º at the top. I shut off the A/C at around 212º. May not be extreme.. but I sure don't like those numbers.. I expect something a little lower.. but maybe not realistic. Of course what probably makes it worse is staring at an Ultra Gauge as it inches upward. In typical fashion the stock gauge only bumped up a sliver!
