I would think that if those fans cool a V8 Ford properly, then they would do the Rover V8 no problems

What about a TD5?Quote:

I think a bigger issue is getting the right fan housing to gain maximum airflow.
Not sure about the TD5 radiator, but apparently the D2 and the P8 radiators are an almost perfect fit for the Ford EL fan setup.
We have a experimenter (victim :wasntme:) with a P38 who managed to pick up a set of Ford fans for 20 bucks from gumtree, so we are awaiting the results of his endeavours

look at the watts on a drive motor.
the dia is one thing but the horses used to turn it is as important.
most of these electric fan cars require that the fan run most of the time..and need air flow on the motor way[hiway].most of my small sedans didn't need a fan above 80 km hour. look at water temps as you tail gate a line of pantec B doubles.
the assist fans you get on A/C units are often 60-180 watts.thes have brushes that are normally rated at 2000 hour. dependant on moisture and voltage noise.i have seen 250 watt motors.
my BF falcon has a single fan with a resister to halve speed. I think its borrowed from Volvo.
so my thoughts--if wrong that on low speed your still using the same amps.
that the alternator needs to recharge.
japanese cars that used variable voltage controllers that will save amps?

I've fitted Falcon EL fans to my Disco and Falcon AU fans to my 4.6 Rover V8 sedan. Both controlled with an FK 55 Delta Current Controller that ramps he fan speed up and down depending on the temp of the coolant entering the water pump. A dial on the dash let's me adjust the temp at which the fans first starts to wind up.

As far as current draw goes, it may be an issue in some vehicles, but the Bosch P38 has a 150amp alternator, so no problems there.
