Actually is was Dan that did the "testing" on his old s14, so I would say that it was done right.

And no, it doesn't run at max, but when you can notice a voltage drop just by turning on the headlights, I don't see how a set of good, high CFM fans with a higher draw isn't going to have a greater effect

and I agree, higher end cars have them because there are significant advantages to them.
difference is though, those cars are designed and built for them.
I'm of the opinion that a e-fan install doesn't require upgrading the charging system.

So what are you considering "done right"
a radiator swap to increase heat exchange to compensate for the lower air flow?
an alternator swap to compensate for the increased electrical load?
harness upgrades to properly handle the increase amperage?
A pulley swap to keep the alternator spinning at more optimum rpm's?

a correct e-fan install should only be the fans, shroud, temp driven controller.
If you can't get the job done, with those parts as good, or better than the stock clutch fan, without sacrificing anything, then it isn't worth it.
