Re: Check this out-nice little 2-speed fan harness...
2 speeds are not exponential, they are...well, only 2 speeds. Still not enough to correctly cool an earlier non-emissions engine.
And, well, the single horsepower it takes to spin an engine driven fan, sooooo much loss of performance, gee, what a determent to a street driven vehicle.
All I was doing with the thermal efficiency was pointing out that it goes away with very narrow parameters of cool to hot.
I see a whole lot of electric fan con job hype advertizing talking points being posted here now, but not much practical and correct application. Keep getting that bogus info off them sales sites, I'll opt to keep getting my info from the engines myself.
