I sometimes wonder why more people haven't simply added an AC or smog 
pump pulley to the crank and used it along with a home brew bracket 
to drive an alternator via a 2nd belt, while adding another idler 
pulley for the standard fan belt to run the fan.


Removing the alternator/generator load from the fan's drive belt 
would go a LONG way towards extending belt life along with making it 
a lot less likely to toss a belt.    Be sure to use a smog/AC motor 
mount bracket.


People modify 'Vairs in many different ways to improve things... 
seems somebody would have done this along the way.   If I had access 
to a machine shop to fabricate brackets I would have... but then I 
don't drive as aggressively as I used to (aversion to tickets) so I 
usually don't toss belts these days.

I know, if it works don't fix it.   But it would be kinda handy at 
the autocross to help keep the belt on the engine.   I've seen more 
than one autocrosser/racer with no alternator on it at all, just a 
2nd idler pulley to route the belt.   ...and no spring loaded idler anywhere.
