[Healeys] electrc fan vs. belt drive

[Michael Salter]

For the fan to absorb 7% of the engine's power that 7% say 10 BHP would have
to be driven by the single "A" sectopm "V" belt.. 
The last time I looked it usually takes a pair of "A" section belts to drive
1/2 a horsepower!!

I'm also on a Triumph forum where a few people have claimed that the
installation of an electric cooling fan (and elimination of belt drive fan)
has increased their Power by about 7%.

 

They claim that the drag created by the fan on the waterpump pulley creates
a power loss that is more than the power loss due to the burden on the
Alternator/generator created by the electric fan.

 

Anybody have any thoughts?
