Ive seen it for sale in NOPI.. No idea whatsoever who makes it, anyone?
ELECTRIC COOLING FANS: The stock cooling fan runs off a clutch which is driven by the crankshaft. This is a cause of some considerable drag, and certainly is not the most efficient way of doing it, as the fan is on all the time. A switch to a high capacity electric fan could result in some considerable increases in power, in the neighborhood of 10-15HP at high Rpm’s. The fan should be triggered by a water temp sensor, so it will only turn on when necessary. In fact, I really doubt the fan is useful except when idling. When in motion, the fan is basically pointless. Note here that the draw rating of a large fan will be around 15amps. This can cause some serious strain on a poor condition alternator/charging system. Make sure your alternator is up to snuff.
