Yes Joe, we are limited in alternator output by our low RPM. If you remember Hanley's alternator drive system off the flywheel with a larger pulley ratio and dual belts, he could get closer to rated output with it that we can with our stock accessory drive. However, looking at the same 35A load on our original Motorola 35A alternator compared to a 100A Delco, the Motorola will be running at max while the Delco will cruise along at 35% of its rating.

I had to slightly modify my alternator bracket for the 10Si to fit. A few minutes with a grinder did the trick.
