200a alt needed?

[Birchman1310]

Hey guys. I'm running a dual pump fore fuel system, 3.2 alt pulley, and a 4lb lower. Do you think a 200a JLperformance alt is needed or can I go with the eagleelectric 180a?

JL is $400
Eagle is $180

I have same set up, stock alt. Unless you need an alt I don't see the point.

Alt is going bad. So I have to replace it.

I'm running the fore dual F90000267's pumps with the Mechman 170 and i constantly see 13.25 or higher under WOT (log from last night was 13.5). Normal drive 14-14.5.

I'm thinking the 180amp will be plenty but wanted some feedback to confirm. I just can't see needing more than that when the only additional electrical components I have is the dual pump setup. Thanks!

I run a Mechman 170a with 3 wire upgrade and Dual GT pumps, dual FPDM's, 1000w amp with a 10" sub.

With all accessories running, I never dip below 14v.

Damn. Ok. 180a should be plenty then

It's not so much the amperage you need to be concerned with. It's the fact that alternators are very finicky on these cars, and cheap-o alternators do not last. This is without question a "get what you pay for situation". The only ones that don't seem to have problems are the higher end ones, such as J2, Nations or Mechman. I would run the J2 200a with wire upgrade hands down just for the peace of mind. I would put money on that 180a taking a dump in short order. Also look into a larger pulley since you have a lower pulley.

I'm personally running the J2 setup with wire upgrade, and it has done me good so far.
