Small Size Alternator

I am having some problems with finding room to mount a alternator on my Anglia,
with the blower drive pullys, narrow frame , coil/overs/mounts Etc.. there just isn't any room to mount a alternator, and have it driven off the crank
my next object is to maybe find a SMALL sizes alternator that could possably be mounted some where other than the front of the motor and be driven by a elect. motor like is sometimes used on water pumps,
Anyone have any ideas what might work?
I have been looking at atlternators off of small yard tractors, but no luck so far,,
I am open to any suggestions you guys might come up with
Thanks Bill

I can tell you what won't work - your idea of driving the alternator with an electric motor. That's called perpetual motion. If the electric motor is turning the alternator, where's the power for the motor coming from? If you really could get this to work, you would immediately solve the country's energy problems.

There is one alternative you might consider. I've seen street rods with the alternator driven off a pulley on the pinion flange of the rear axle. Naturally it doesn't charge when you're not moving, so keep idling to an absolute minimum.

Another thought is to turn the alternator around so the pulley faces towards the rear of the car and drive it off the inside of the blower belt. This might be a problem for radiator clearance, however.

Check Scooters web site at Project33, he had a unique way of mounting his alternator.

Thanks Vince,, thats quite a interesting site Scooter created,, and some fantastic ideas,, which I hope he don't mind me using the reverse mounting idea,, ( THANKS SCOOTER )

And Thanks Joe,, never know how stupid some ideas are untill you open your mouth ,, and insert foot,,,
after reading Scooters article,, I went out and mounted the front fenders and Grill shell.. The radiator sets forward enough to get the altenerator in there.. it will have to be on the Pass. side, because of the degree wheel pointer..

Thanks guys...

Your welcome, Scooter assisted me greatly in the build of my 34, even made some long distance phone calls. He's a great individual and does not mind sharing his ideas. His 33 build has been finished now for a couple of years but he keeps the site up and running for the benefit of other rodders.

another dumb question on alternators,, do they all charge regardless of the direction they are rotating? or is it just the cooling condition with reversing them? or is this Power master special built to charge in either direction,,,the reason is ,, the cost on that 8142 Powermaster is right at 500$ ( don't know if that is list or my price)

I have 3 new altenators that I could use if they charge either direction. its worth the dumb question if so,,,,,

This does not answer the question just mentioning it. Have seen an alternator driven off the rear end, it was a race application.

The power master is small and 100 amp http://www.summitracing.com/parts/PWM-8-881/?rtype=10

this one is small only 60 amp http://www.summitracing.com/parts/CTR-77-500/

reverse direction , never though about it, but we are talking AC, the alternator cooling would have to be addressed . to find out take any alternator to the local AZ and have them pop it on the test stand twist the drive belt and see what you get ... Report back I am curious ...

Thanks Pepi,, those are the new Rocket Launchers that were just introduced at SEMA,, copy of the ET but at a MUCH better price, 180.$ each,, got em from Nostalgia wheels,,

after doing a little searching I came up with a small alternator , rated at 55 amps,, not sure that would be sufficient to run water pump, fuel pump, MSD ignition, and charge the batt,, and maybe some lights
gonna keep looking some,, You guys think 55 amps would work??

Oh Yeah,,, you were wondering if all alternators will charge in either diration of rotation,,
every thing I could find said they will all charge but need to have internal cooling fans,,

They will charge in either direction,only concern will be cooling fin direction....here is one on my welder that I am building with straight fins ,I have ran it at 130 amps for combined time of about 1 1/2 hours with no problems.This one came off a tri axle GM dump truck....
Good Luck.....Love your build!
