Alternator Upgrade

[thomo23]

Just wondering if someone can give me some options for an altrnator upgade for s1 RB 25 as with the upgraded fuel pumps ( surge tank ) and thermo fans etc. seem to drane the battery on long stop start trips.

i'd be pointing more to the battery upgrade than the alternator

I was thinking of doing the same thing with my altrnator along with a bigger battery to hole more power for audio set up.

Battery has been upgraded to a large calcium item. Its just the draw of all these ancilliaries which brings current demand close to the limit of the stock alternator. I am a sparky and have tested the alternator. I was just wondering if there was an alternator that fits onto the rb 25 that has an increased capacity and where to track one down.

Don't calcium batteries charge at different rates, or react differently when not charged at the correct rate.

I've been told that putting an ordinary battery in a car designed for a calcium battery is a no-go..... and putting a calcium battery to replace a normal leadacid battery will shorten it's life and charge capacity.

Have I been misinformed?
