Smallest, lightest alternator for N52

MWC · 11-19-2021, 04:19 PM

I am building a race car and the alternator I got on ebay for my N52 is a beast and super heavy.

Are the bosch AL0841N and earlier AL0839N models the only alternators that came on N52s? Is there something out there that's much smaller? 180 amps is way overkill for what I'm doing.

FCP euro shows a 155 amp alternator as being a possible fit, no idea if it'll work for you though.

Depends on N52 or N52K. Part numbers for the same AMP are different for 06 and 07+ ones; Though I'm not totally sure of the difference
