www.alternatorparts.com has a ton of big amperage units for lots of different applications...up to 350 amps !!!...nuts Randy does good for a one man shop out of his garage, I would have to say he has to be the most creative guys out there. As far as stepping alternators up to higher amperage from a small alternator you always have to lose something, heat issues, less charge at low RPM. OE makes as small as they think they should to keep things reliable and with the charge being at the RPM's they want. If they could keep making them smaller, they would keep shrinking them until they look like a micro chip by now. You can step most alternators up 35-40% without losing a whole lot of low end power. I guess it depends on what you are using it for. For drag cars you can step them up a lot and keep it small, high RPM's and short run time, perfect. I sell parts to starter and alternator rebuilders for a living. For the CS130D (normally 105 amp) I think I have a couple hundred 200 amp stators on the shelf to step them up. I talk customers out of buying them. They don't work worth a darn. Kids think they want a 200 amp alternator to run their stereos, fact is these put out way less power idling and driving around town then their OE alternator. They make power but the RPM's must be screaming. Larger alternators step up power much better

With my fans and all acc running the voltage meter drops to around 12volts...I watch it like a hawk. I got the alt off a Honda CRX years ago.Not even sure of the amperage. But it works. If I need to upgrade I'll contact you.

CS130D is a Delco unit, it's pretty good. I think I read you have a Denso on yours now Mr. P? I would just up that one to your needs, less weight, less rotating mass, everything already lines up and you don't street drive it I will be using this on my Rampage.. its street driven with injection... the part that Willie shows below is pretty much what I think I need but with a single pulley.. assuming this is the same size as the 70a thanks

They are pretty good work horses, just a little large. They make self excited regulators to make them a 1 wire too Cool, thanks. So it puts out decent amps at idle? More than the toyota self regulated one or the same? I understand it depends on idle rpm and whatnot.
