Duel Alternator Pullies...any NON underdriven?

I need to pull off my Air Pump because its bearings are shot, the exhaust is replaced now, so I don't need to pump air in the catalytic converters.

But I need a duel alternator pully to prevent belt slippage on the water pump, the only thing is that I do not want to increase stress on the alternator by reducing its RPM by %20.

Any ideas?

You can also use a lawnmower belt on just the eccentric shaft and waterpump pullies, in the groove for the airpump belt. Works like a champ, and CHEAP.

Only problem with the yahoo belt is that it puts an unusually high loading on the waterpump bushing
