    Pheonix Gold or Stinger

    I have a pheonix gold ...dont remember the model number because I installed it about 7 years ago, but it puts out 175 amps on a Dodge Ram 50.

    About the horse power statement. Technically yes, your engine needs to work harder, but you wont notice it. You cant even feel horse power to begin with and 2nd it will not affect your gas miliage. I have been using this alternator for 7 years and my gas miliage is the same.

    I use a battery isolater to 2 red top optimas and never have had any issues running my 375 amp stereo (300 for bass and 75 for highs). Never cuts off and never goes below 12 volts.

    I would look into a Stinger dealer. They usually will set you up with the kit and instructions. Its not cheap though.

    Don't go dual alternator. There is nothing wrong with it, but you can get alternators even higher than 200 if you have the money.

    Frodo, if you want true isolation i would go with 2 alternators.. i ran a pretty hefty system with a dedicated 130 amp alternator to the back battery and i never had any problems.. i lost mabye .5-1MPG and no noticable HP..
    i picked it up for 100 bucks and never worried about it until i sold the car.. i put about 120k miles on that set up.

    I don't think they're still making them. Checked their site and didn't see anything listed. We used to carry them when I was doing installs though and never had any problems with them, they always worked great. The Ford one may be the way to go though since you'll have less trouble installing it than with an aftermarket one I would think.

    check to see what kind of output it makes at idle, and what output it has at high rpms. realize that lower outputs at idle can lead to dimming at stoplights, or poor performance at competition.

    make sure the alternator will perform how you want. If you only want 130 amp output, you shouldnt have to buy a 250 amp alternator just to get that output at 800 rpm....

    so im taking it that roughly ~ 838 rpms is average at idle?
    Is there a indivdual constant for an alternator in amps per rpm or does it exponetaily increase?
