<VV> MY ALTERNATOR CONVERSIONS

[corvairs at pacifier.com]

Tim - My youngest brother was a commercial custom electrical component
rebuilder for nearly 20 years and he said that anything over 75 amps in a
Corvair alternator was a shaky proposition.

The reason is the small contact area on the pulley made by the Corvair fan
belt. You get much above 75 amps and start getting slippage and other
problems.

As usual, his standards were based on a safe margin, and like many things,
your experiences may vary.
