Charging Issue Question

I would suggest getting a higher output alt. The stock unit only produces 45-55 amps which is just enough for the car, AC, and a basic radio. With all of that and an electric fuel pump, electric fan, an MSD, and not to mention any better radio you probably need closer to 100 amps.

I had the same problems so I got a bigger and bigger one, then I calculated that my stereo needed most of the amperage I was producing. After that I went with a 200 amp powermaster, with no problems since then.

I agree. Running an electric fuel pump and msd is probably a little much for stock alt. If you are also running reduction pullys this will also add to the problem. I'd go to 100 amp minimum.
