They told me if I ship an old alternator to them they'll rebuild it for $195 with an upgrade to 200 amps including return shipping.
See below for the text of my emails to and from them:
The regulator has a high cutout point of 14.7 volts. This means that the highest voltage will be 14.7V. Voltage will vary in the system depending on the output ratio of the alternator. When amperage goes up, voltage goes down and vice versa. Voltage rarely remains constant when you have heavy loads such as with a stereo system. The best way to keep voltage higher is to use and alternator that is rated much higher than the load demand that you need.

I forgot to ask, do you guys set the voltage regulator at 14.4? Can we tweak it to 14.5?
Thanks!

Subject: Re: 1994 Q45 alternator upgrade
If you would like to ship us your alternator we can upgrade it to 200 amp (including bearings, brushes, etc) for $195.00. You would be responsible for shipping it to us and we would include regular ground shipping back to you in the continental US. Our 200 amp alternator will provide about 110 amp at idle and should reach max output by 1600 - 1800 engine RPM. These numbers are from our testing at a 750 RPM idle with a 3:1 pulley ratio. You numbers could be slightly different depending on your idle speed and pulley ratio. We have no problems with the cooling at that amperage.

I would like to send in my factory alternator from my 94 Infiniti Q45 base model for a rebuild and amperage boost. I would like to get between 180-220 amps, and would like to know what amperages would be available at what rpms.
I would prefer ALL serviceable components replaced, including bearings. I am also concerned about adequate cooling for the assembly, so if you could detail how that would be addressed I would appreciate it.
Turnaround time is not critical, as I will be sending you a used unit that is not in the car.
Please send price and specifics as to what you can do for me.
Thanks!
