Alternator in place of the A.I.R. Pump?

[Lil-Pony]

I was reading some post about winchs and car batteries and i read a comment on a second alternator being installed... Has any one done this with a 2.8? I was thinking of placing it where the air pump went since the bottom braket of the pump will fit an alterntor as well. My one worry is i dont believe there will be enough belt contacting the pully for it to be effective... Yalls thoughts...

does anyone have a comment on this ideal?

Not sure if it would work or not, don't see why it wouldn't with a bit of knowledge and tinkering. May need a different size belt or the stock smog pump belt may work. I don't have the pump bracket or I would try it myself in my B2.

i may have to try to mock up my old 60 and see if it would fit.

What would be the advantage of adding another alternator? I would think just upgrading to a high output alternator and adding some relays for running high amp draw appliances would be a better alternative. Just run the addons directly from the battery those military style battery clamps make that real easy.

I alread have a 140 amp alt, and i was just wondering what i could do with my old 60. And i thought of this.

The high amp alternators are kind of pricey. You can get dual standard output alternators for a fraction of the cost of a high amp alternator. Not to mention the likelyhood of a dual alternator setup having both alternators fail at the same time is very slim, so that's kind of a failsafe, if one alternator fails, you at least have the 2nd alternator to get you to your destination.

Also...
Most high amp alternators make less power at idle then a stock alt. That would be a big benefit when sitting at idle trying to winch yourself out of a jam.

Yeah, they seem to be RPM based for max power output. Dang wish I had an air pump bracket I have a spare alternator and wouldn't mind trying it. Guess I should make a trip to the salvage yard just for a bracket, expensive trip though cuz I'd have to drive my truck not the B2 due to the continuing alignment issue.

I think have both the bracket and alt. in my garage, i just havent gotten around to test fitting them, i also dont have my b2 to mock it up in right now either. Ill post pics of the alt and the bracket to see how well they fit tomorrow.
