why? This alternator puts out more at idle and at full tilt. And it isn't made from one off parts and can be rebuilt by any alternator shop.
You dont necessarily need more. Unless someone is running a lot of lights, snowplow, or a big stereo, there's just no need for that much current. Just putting a smaller pulley on helps the IDM and FICM significantly. RPM is negligible on DC motors/alts. Until the bearings fail, lol.
In your 2nd video it appears your first alt's voltage regulator it just starting to wig out as its only charging between 11.8 to 12.?
I'm not saying the one your offering is bad by any means, but DC Power is awfully hard to beat with their reputation. Their OEM alt isnt quite as high output as yours but its $299 and puts out more amps at idle than the other.
Heck Matt, see if you can be a dealer for DC. As there can be a significant wait time for them. I'm sure they spend more time filling dealer orders than customer direct orders.
