what are my options. Got a brand new alt on there now, but it can't keep up with the heat, the lights and my stereo amps.



Anyone got any ideas?

GM powermaster- ask Jim

FD alternator

or my choice: have your alternator rebuilt and upgraded by a local rebuilder and get a warranty to boot

I can get the powermaster through one of my suppliers, how does it bolt up?

I believe the only thing you have to do is buy the 2 wire pigtail

that fits it, which any auto parts store sells, then clock the alternator

so the bolt holes line up. Swap pulleys and I think your set.

all told thats like a 1/2 hour worth of work.

Bolts to existing mount huh?



That would be all right.

The FD alternator would probably be a better option than the GM alternator. That silverrotor guy on teamfc3s.org is selling them brand new for about $165 shipped. You can even get a dual pulley at no charge. He also gives you the required connector. A good S5 alternator would be another option. They put out a little more than the S4 alternators.

Yes, it bolts right in. It's too shiny with all of that chrome crap. I'm used to my dirty aluminum parts under the hood. https://www.nopistons.com/forums/pub...#>/biggrin.png

if i recall correctly..

fd alternator is a 10amp increase from the fc..

The S5 is 80 A. The FD is supposed to be 100 A.
