    Hi, I'm gathering up the parts I'm going to need for my Regal. Car will have electric fans on radiator, electric water pump (I hope), electric fuel pump, and has a MSD 6 box. I was going to get a Odyssey battery PC925.

    Summit Racing has an 80 amp alternator on sale for $59.00. And they are even powder coated in red/black/blue. Will this alternator be enough to keep everything powered up? Thanks.

    yeah,they look nifty.if you are actually planning on the alternator lasting any length of time,stay away from any kind of coating,powder-chrome-paint.it acts like an insulator,and keeps the alternator from cooling properly.on a low amp unit you can get away with it,not 80amps with all the accessories you want to run.it is a 10si,not built to disperse the heat very well.my alternators are cs130 modified for the heat/hi amp.compare mine to the powermaster pwm-17864 at $329.95 :shock: if you really want the powdercoating and hi amp,stay away from the 10 or 12 si.they wont last very long :mad: i am actually trying to buy a powdercoating system,and will offer them in the future.(cs-130 style)

    Thanks for the info. I don't know much about alternators, that's why I'm asking here. Didn't think about the powder coating retaining heat. Just saw that they were on clearance at Summit. Time to keep lookng.

    I can buy Delco cs alternators at the yard for $25. There are a few tricks to make them work in non compute controlled cars (need to wire in a 75 ohm resistor.) Can think of a lot of things to spend the extra $300 for. Also a used Delco is better (imo) than a rebuilt. I will look up the wiring directions for the conversion this weekend if you want to know.

    Interesting. I'm not one to put colorful things under the hood, but then again, I do really like purple.
