"consuming hp through the pumping losses associated with
maintaining operating pressure in the restrictive closed
system. Lexus claimed that the hydraulic fan consumes
much less hp than an electric, and is much quieter too."
I've got to dissagree with Mr. Lexus. Electric motors
and generators can often run better than 90% efficent.
Hydraulic pumps and motors are closer to 70-80%, if that.
Plus, the electric only kicks in when there in insufficent
ram cooling air, and the complexity of the extra hoses
can easily be offset by a well installed electric system,
maybe one with dual, 2 speed fans, set 5 deg apart.
anyway, I'm currently sticking with the stock fan, after a
few moments of warm-up, the viscus clutch releases till it
gets really hot.
