Uh... no. It's definitely at fault. Stockers were only 75 amp. Swapping all pullies except the alternator resulted in no problems, but replacing the alternator and crank resulted in a lack of charging in my car. I swapped the stock pulley back on and no problems. Funny because I could keep the car alive during the day for a while, but with the lights on, there was no chance. I think I was still running a stock coil at the time. Don't know how you pulled off the E-fan and all pullies. When I upgraded to an e-fan, I also upgraded to a 90 amp autozone deal to keep things humming along.
With the new combo, computer stuff, and all new badass stuff under the hood, I went with an equally badass 200 amp PA performance deal. Hopefully, that quenches any electrical thirst I ever have. I'm sure it's overkill, but between the BS3, MSD 7+, "high voltage/current" HVC coil, dual electric fans, insane fuel pump, etc, etc... maybe even a sound system one day? 200 amp should have me covered
But... and I'm definitely ignorant on electrical systems... My theory is that a given alternator draws the amperage that the system currently needs. So, I question the use of alternator pullies altogether.
