clutch fan gap too short

@65 Cuda 340
A lot of unknowns about the chart.
Was that measured with air of various speeds blowing on the fan?

Was the viscous fan the same diameter, number of blades and pitch as non viscous fan?

Most of the time our engines are not at 3500 RPM or greater. If you are drag racing I would not want a viscous fan rotating at 4000 to 6000 RPM, wouldn't want any fan rotating that fast.

I'm not flaming you I just do not feel the chart is presenting a complete story. On a Dyno sure, fan draws power. In the real world the difference in nominal.

If you want ultimate power from the engine add a second battery. Have electric fans, elec water pump, and elec power steering pump. The battery is not hooked up to the alternator it is only externally charged, you just gained 5 hp, remove the alternator too and use another battery externally charged to start the car, 1 more hp, at 3000 rpm. Sounds silly, but if you are going for the parasitic losses....

Just my 2 cents
