Alternate alternator

I have been running an idea around in my head and would like to get some input from others in my field. I wish to add a second alternator to my truck, but do not have the room to add the pulley and such because of the ram air and other add-ons on the accessory belt, as well as the fact that I'm running that belt at 24% underdrive. I do not wish to upgrade the existing alternator(besides the largest I've found is 150 amp) because of the underdrive, coupled with my experience that high output alts act like undrive pulleys at idle as well, compounding my problem. On to the idea. I have found a device which, by its intended design, is intended to turn a factory water pump to free up horsepower from the accessory belt. My plan is to adapt this mjotor to spinn up an additional alternator. The motor will run off the factory charging system abd draws only 8 amps. With the correct pulleys, the second alternator could produce its full rated output nearly all the time and charge a second battery and runn the audio system, freeing the factory alternator from the burden of the audio system entirely. Another benefit would be that the alternator could be remotely installed, thus freeing up space under the hood. Of course there must be a flaw in my logic on this idea, so I turn to you for thoughts...as well as constuctive criticism. Masta N out

It couuld work. Try it and let us know. Paul

Not neccessarily perpetual motion(and I considered that part of the equation) because it is not powering itself. It draws power from the main alt. By the way I'm thinking, it is much more like a lever, in that it amplifies the energy(effectivly) from another source...do you follow? It might not work, but I'm not convinced that the perpetual power argument really holds water under these circumstances. Especially if the motor spins just as fast as the accessory belt on the truck, does the alternator know how the spin was imparted?

I'm telling you, it'll work. Try it. Hmm.. maybe, just maybe. *Twisted grin* Paul *Edit* The only problem I think you're going to run into is the motor you have turning the alt will have to run at some seriously high RPM's for a LONG time (however long you have your car running). Most electric motors arn't designed to run continusly at high RPM's for a long time. That, and the motor would have to have some pretty good torque to turn the alt.

It is designed to turn a water pump...A job which is by far more demanding than turning an alternator...and the run time is the same as well...the entire time the car is running.

Do you have a link to where I ould check out this product?? Paul

Not a link...but I can tell ya where to look. Go to summitracing.com. In the online store click on cooling. I think it's called an electric water pump motivator...or something like that. It's made by various manufacturers, but the one that is the least expensive is made by Moroso. Sorry I can't post a real link...we only have limited internet access at my work...but I arranged to have this site viewable;). I think Jeg's carries them as well. When I get home I will post an appropriate link for you.

Actually, as per the dictonary     Perpetual Motion:The hypothetical continuous operation of an isolated mechanical device or other closed system without a sustaining energy source. By your line of though a simple lever would be perpetual motion...which we all know is incorrect. One can, with the proper length lever, apply 2 lbs to move 200lbs. The moroso unit's instuctions do not mention using the unit only intermittently http://static.summitracing.com/global/images/instructions/mor-63750.pdf .
