I want to eventually run underdrive pulleys, electric fans, and my stereo pulling 38 Amps MAX. What size Alternator do I need to power this, or could I get by with a capacitor and an Optima battery?

And would pulleys and electric fans yeild a nice power increase, or can yall recommend something else?

 

I would get the biggest one you can afford, but a 90 amper would probably handle it easily.

Yeah the pullies and the fans work ok, but i would rather save for a supercharger, something you can bolt on and get 200 horses instantly instead of getting 5 at a time with the little mods.

Lets see, I run a 600 watt jensen amp, and i have locking doors and elec. windows, and a few other things, and my NEW 80 amp handles it great, i got it from o reillys, 139 dollars
