I find that the fastest way to increase Horse power

Yes, it has been done. By some guys who do not post in here much anymore. And it worked well when set up properly.

But I personally do not have the details.

ok, here we go. I am starting to see how is going to be posible. After some preliminary mesurments if you put a standard electrik fan with the size of the original, the motor more or less does not fit, <img src="/forums/images/graemlins/confused.gif" alt="" />
But I came with the idea of leaving the fan as it is free wheeling on its original axle, place the motor near the altenator ( mayme usung the same mounting) and driving it with a belt after ofcourse ripping of the engage mechanism.
pros: adecuate motor - possibility of regulating rpm's
cons: more complex having to modify motor to put a driving wheel, capasity of the alt. base to hold the weigh.

Question.
will it eat the free wheeling all the HP gained?

I leave the electrics for a later post.

im confused, how is an electric fan a HP gain? <img src="/forums/images/graemlins/confused.gif" alt="" />

I've seen this in a competition sportage. The guy fitted the electrical fan in the original place, but had to reposition the radiator about 1 inch to the front of the car (some trimming on the body was required)

it's not. what it does is this: it takes a power-robbing belt out of the picture. the fan belt is run off the crank pulley and when the clutch kicks in, it makes the fan difficult to turn and therefore robs some of the HP directly from the crank. an electric fan only robs electricity from the battery. with an electric fan, you never get that variation in HP from when the clutch kicks in. the consensus is that that usually robs about 10 HP from the crank, but my opinion is that that probably varies greatly with altitude and age of the pulley bearings and all that.

Wow! 10+/-? That is an appreciable amount.

I think I am excited about this idea. Sounds like it might be kind of fun to try.
Does the electric fan cycle through a thermostat or will it just run all the time and will orig fan belt/clutch removal affect engine idle, up/down whatever?

Good luck Fokion. <img src="/forums/images/graemlins/kewl.gif" alt="" />

You need to cycle an electric fan with a thermostat, and even though the electric fan is not driven directly by a belt connected to the engine, it is driven by the alternator which is driven by a belt.

The battery doesn't actually drive any electrical components unless the engine is off and then when you start the engine the alteranator must make up the deficit in the battery so the net is less than 0 because the alternator is not 100% efficient.

Please forgive my wordiness.

What is behind the bullnosed pulley that the viscous fan is mounted to? Could the entire assy be removed altogether to create a bit more room for an electric fan?

One other consideration is that when you remove the factory fan clutch, a whole new belt size will need to be found somewhere, as the same belt that drives the clutch drives the alternator.
I guess an option would be to just gut the clutch but keep the "shell" in place. That way you could still use the same belt. (Hope that shell doesn't get in the way of the new electric fan, however)
