i have been doing some reading and have found out i have a 90 amp alternator. I will be drawing 475 watt rms (max) from amps which would be a 32 amp drain on battery. If i upity the wire guage from alternator to battery to a 4 guage, and the chasis ground from negative terminal, I think i will do without the cap for the time being.

Does this sound sufficient? Am I gonna have to upgrade the alternator?(which i will next time, but was not counting on right now)
I have a 148 hp motor(roughly 110kw)
As always, I very much appreciate the feedback.

 

Check back to your other post.

 

eventually yes, but it depends on so many factors. if you plan on expanding your system in the future than you should consider it. a stock alt will take the abuse for so long until it gets tired and fails. don`t forget that your cars electrical system needs 50-60amps to operate, and whats left is reserve capacity, but also note that you have a loss of amperage due to heat of about 20-40% at operating temperature. if you do the math there goes all your reserve capacity.

your poor alt has to work so hard for the same amount of pay, one day it`ll want to retire early?

 

Damn mayhem, you're going to make me shed a tear.
