Alternator question

[Gbob2003 10+ year member]

So I was looking into getting a performance alternator to replace my stock 80 amp in my 2003 mustang. Is there anyone that knows of an alternator to fit my car? All im seeing is like 120 amps. I wanna get at least 190-200 amps. Any places I should look that im missing?

check out excessive amperage, nathan treated me very well and the alt performs amazing. not to mention he was a good bit cheaper than everyone else i got quoted.

can you have them build the alt to perform at a certain voltage or is that only if you get the regulator

Most votage no days is regulated by your cars computer so alt swaps typically will not change your voltage.

alright thanks

Go with DC Power Engineering. I got a 320 amp alternator from them for $500 for my car. They are able to make alternators that will do 200 amps at idle and they will also run at 15.1 volts since their alternators actually bypass the cars ecm. They can make an alternator for just about any vehicle so they could get you covered.

no... most alts today have an internal regulator that regulates the voltage... your car's ecu has nothing to do with it...

the reason most use external regulators, is because of their adjustability on the fly...

kangaroux... you can ask them if they will build one with a different internal regulator in it, for higher voltage... but they wont make one like that a production model, as most people will only use one HO alt for their setup, and an alt that pushes like 16v is completely useless in that situation
