A 130A alternator is a common OEM size. I think you will find this is a "peak" rating of only a few minutes or so. It's continuous rating is about 50-60A, called a "duty cycle". Also the drive belt/pulley system is usually only designed for about that amount of torque without protest (squealing).
I have seen rebuilts with a warning label attached with "Install only on a vehicle with a fully charged battery or warrenty is void".
I have noticed if the alternator is physically small it's continuous output rating is also small. Size does matter.
