Difference in DC Power Alternators.


Recommended Posts

I currently have DC 270XP and was looking into getting a 370XP but I noticed that the idle amperage is lower than my DC270XP?

DC270XP

Output Voltage 14.8 Idle Amperage 190 Hot Idle Amperage @ 200ºF 170 Max Amperage 270 Hot Max Amperage @ 200ºF 240

DC 370 XP

Output Voltage 14.8 Idle Amperage 150 Hot Idle Amperage @ 200ºF 130 Max Amperage 370 Hot Max Amperage @ 200ºF 330

Why is that?

Current Build:

1999 Tahoe #ComingSoon

Previous Build(s):

Crossfire Magnum

5k Pontiac G6 GT

Basically with big alternator like that, the whole output curve is shifted up in RPM

internals are the same. if its a 370xp its a 370xp. the case would not effect the idle that much. only thing i cna think of is becaue the alt may not spin as fast on that car at idle so it wont make much amperage since larger alts have a higher turn on. if that is why thats pretty crazy they went through to change that for every vechicle.
