Can I use a spacer on my cooling fan? Will it throw the water pump shaft out of balance? Looking to put a 1/2" spacer cause my fan is to close to crank pulley. Any ideas?
Yes, you can use a spacer.
Just make sure you use a good quality manufactured spacer and not some home fabricated piece and then you won't have to worry about the balance.
See my problem is ever since I put the supercharger in, the crank pulley being for two belts now is maybe a 1/4" away from the fan blade. Now my stang sounds like a Mack truck with that loud wooing noise never had that problem b4. Fan clutch is new I figured if I space it I'll get it to quiet down.

I was told that the air bouncing of the crank pulley is causing that noise.

Yes, I could see where that might be the case.
You could also get rid of the engine driven fan and install an electric fan if you wished. That would free up another 10-20 hp at certain rpm's and get rid of that noise and clearance problem.
True. I would also have to get a better alt. 130 amp perhaps. But those electric fans are also pretty loud when they kick on. If the spacer don't work I'll take that route.
True, but depending upon what all you already have (ignition, stereo equipment, etc.) you may need a bigger alternator anyways.
The only time I ever really notice my electric fan is when the car is idling sitting still. :good:
No, you are not wrong.
The engine driven cooling fan is powered by 200-300+ HP.
That would be hard to beat with an electric fan motor.
BUT... It puts out way more air flow than is actually needed to cool the engine.
So, it is really wasting all that air flow and the fuel being burned to produce it.
2000at idle and it slips as rpm's rise. It's probably closer to 4000 when the clutch engages though, but it starts slipping again when the engine cools off enough.
Question....would I need a larger alt with a single elec fan?...no a/c no radio 1 power window (pass window does't wrk)....the kicker is I have underdrive pulleys...im sticking with clutch fan just a random question..

after i installed my electric fan and underdrive pulleys my battery wouldnt charge at idle.i had to put the stock alternator pulley back on then it was fine.
Figured that....well atleast my clutch fan runs on gass!!...no electric fan in my near future...the less wires the better(in my mind)...i dont even like my power windows blah!!...i want manual window regulators!..
