Measuring Alternator Needs


Recommended Posts

Ok guys...gettin ready to purchase the amps for my truck, but I need to know how to figure out what size alternator I will need to replace mine with? Of course it will be an iraggi.

My truck came stock with a 136 and I know on a cold day that my grid heater draws about 80 upon startup.

The two amps that I am purchasing are the Soundstream TRA-960.4 (fused off at 100) and the TRA800.2 (fused off at 80).  Now even though the fuses are max draw and being that I won't be competing and have the power up max pretty much at all, how do I figure average current draw? 

Also, the truck has stock dual 960amp batteries.  Do I need to worry about stacking additional batteries (hopefully not, don't have the space to do so).

Thanks guys..

Unfortunately it is not as easy for me to get a huge alternator as it is for most of you guys.  Why...Diesel Powered babbyyy.  In english, my truck redlines at 3200 rpms.  Most gassers get their peak current around the 4-5 k range, where as I need my peak power down in the 2k range.  So that's why I need to figure out what size I need, then start working with Dom to get one made for my truck.

Yep...that's why I'm trying to figure out what size I will need, so that I can start working on pulley size and then have him work on the making it work.
