Alternator Recommendation

I have been contemplating the same issue(s).

First, you should be able to calculate how many AMP's your combined equip (include headlights, blower motor, horn, etc...) will pull and add 20% to get a reasonable idea of the size you might want.

Next, the wiring must be up to snuff to handle high loads, including proper fused circuits and fusible links where needed.

The ONE-WIRE concept is somewhat misunderstood from what I can see. One wire usually means that the alternator has an internal voltage regulator. The regulator keeps the alternator providing the 14.x volts as required. The problem with them are that most styles get their voltage reading at the alternator output location. Long primary wire runs and bad wiring/corroded connectors (and weak ammeter gauges) all conspire to drop line voltage and you may well end up with 12.5 volts at the actual powered component which can really affect the performance of the component.

Fortunatley there are ways to wire "some" of these (GM models esp) so that they get their voltage "reading" at the end of the feed wired run and where the remote devices tap from so the regulator can more correctly supply true 14.4v. Check out the tech articles at www.madelectrical.com/ for their reasoning and reccomendations... they have some great tech articles to explain this all in general.

I think I am leaning towards the Powermaster PWM-8-57529 140amp alt, wired with the kit from MAD to allow remote field sensing. The issue for me is I have eddy aluminum heads and an electric WP so may have to fab my own brackets. There are also some threads on here with links to a company that makes brackets for other GM and Nippo alt's.

The bottom line is most of our cars are not designed with 80+ amp alternators in mind and some creative wiring, bracketing, and attention to saftey-devices within the circuits is required to get it right. Good luck.
