Is the electrical fan conversion any good?

[jondee86]

The fan absorbed power that is stated, occurs at around 7,500 rpm
engine speed. The fan is overdriven. I don't have the measurements
to hand, but I'd guess by about 30%. In round figures this will give a
fan speed of 10,000 rpm.

Now, the Fan Laws say that the power absorbed by a fan varies as the
cube of the rpm. So, even in the absence of any data on airflow or
pressure, I have no difficulty in believing that the OEM fan could absorb
8 hp. Dyno testing is probably more demanding than actual road use,
as there will be less airflow thru the radiator from the external cooling
fans. And the viscous coupling tightens up as it gets hotter.

Having said that, I still use the viscous fan for everyday driving, but I
do take it off for circuit racing For a dedicated race car I would use
an electric fan and thermostatic switch.
