Is this super cap overkill?

Recommended Posts

Currently run a pair of sundown SA12s off a dc 2k and a RF P600x4 on a set of t1 components. My voltage stays around 13.8-14.2 unless I’m dipping into a really hard song then it gets down to around 13.3 ish and jumps back up to 13.8-14.2.

I have a mechman 240A 

two runs of 1/0 from front battery to rear

front battery xs power d5100R

rear battery d3400

around 125ah of xs power I think

 

Upgrading to a Fi sp4v2 15 on a AAK 4000.1D or the 5500 variant. 

 

Would this be overkill? https://www.down4soundshop.com/SB1260-31/

Im thinking of running this next to the D3400 or grabbing another d3400 or selling the d3400 to grab a group 31 

 

daily driver if that matters. Appreciate any input you guys have and any personal experience

No such thing as overkill in electrical

 

With that said, for over 800 bucks, I think you might see more benefit dollar per dollar from getting a larger alt

Last I checked Mechman only made up to a 240a for my civic sadly

 

would I see any benefit to adding the smaller capacitor they have of 500F for around 450$ Versus just adding more regular AGMs with my current 240a alt? (In a daily ride not a burp) 

 

so with a 4K/5k total system 240a alt, how many ah of AGM would be a good starting point ? 250 or 300? Or something else with supercaps ?

You sure your pulling max from the alt? Clamped it ?

Haven’t clamped it. It’s possible I’m not, between the eld bs and the belt never being quite right ...
