Alternator upping amperage suggestions, I already up'd to 75 amps... not enough. Options

[pnewman]

Ok Ok Ok.

I have to many gadgets in my car for a 75 amp alternator to support. They all work great but they are pigs:
Heated seats
high power stereo
Sub woofer w/ amp
HID headlights
windshield washer pump
Interior / map lights in rear view mirror
etc.

So I have a seperate circuit and an electrical sub-panel to support the load safely but simply put:

"I need more power Scotty!"

Took my old 50 amp Bosch to an alternator / starter rebuilder and after looking at it a bit they recommended the AC Delco 100 / 105+ amp single wire alternator with integral regulator for $110 rebuilt. He stated that it could run the dash idiot light too.

Not quite ready to bypass the voltage regulator etc.

I am sure this mod is probably old hat for some.

Thoughts?

Thanks in advance, (IMG:style_emoticons/default/driving-girl.gif)

I don't see why you would ever run a one wire setup.

This is for a different vehicle but here is a link to a discussion on one vs. three wire connection and converting from a externally regulated alternator to an internally regulated alternator. Bob Skelly's Alternator Site

The CS series alternators and the 12SI series are supposed to have excellent cooling.

What would you use for a pulley? I think these typically spin at about 1/2 engine speed. The pulley on the fan is pretty big which means you should have a big pulley on the alternator. The pulleys on modern alternators are pretty small. Maybe they are suppposed to spin faster.

I spoke with an alternator / starter rebuilder and he was trying to pitch the GM unit. One of his pitched pro's was it's smaller pulley which he stated: will provide higher alternator rpm at idle; giving you more current at idle which is a shortcoming of larger pullied units.
