High Output Alternator - 4.6L Engine
I'm wondering if anyone has any knowledge or experience with high output alternators for the 4.6L engine. The stock unit is a Denso SC-1 which I understand is rated for a maximum output of 140A. I'm looking at trying to increase the idle output because I've added some power hungry options which are often used during idling. I believe the alternator itself can handle the overall load I have. I've contacted a couple of specialty shops who don't have a solution for me. In the interim I'm going to try and reduce the pulley size. Currently there is about a 2.5" pulley and I have a 1.75" on the way. As it sits now, everything is great if I increase the engine RPM slightly.
Thoughts will be appreciated.

i have seen ur style alternators re-wound to a max output of 200 amps. most alts will put out 70% of its max rated value. so effectively that would be 140 amps @ idle. which sheould be plenty for any addition 1500 watts rms or less.
but im suprised that a starter/alternator specialty shop wouldnt help you boost the output.
