914World.com _ 914World Garage _ ? Better alternator

Posted by: jwalters Jan 15 2005, 10:23 AM

IPB Image Hi guys, has anyone here modified a better alternator to take the place of the stock meager one? I would like to go with an internal regulated one wire model--or any other model which puts out more amperage.

Thanks in advance-

Look in the vendor section for davep. He has the stock unit rewound to put out more current.

I believe that Griznant from the shoptalkforums BBS modified the drive shaft on a GM "one-wire" alternator to accept the stock 914 pulley. (Turned it down on a lathe.) He then bolted it right up to the 914 motor in his 912 (stock cooling, not an "upright" conversion). No provision for getting cooling air into the alternator housing like the stock one has, so durability may be an issue.

...Or may not, time will tell!

Davep bumps the stocker up to 75amp which should be plenty. Stock is 55amps.
He's a real good guy.
