High output Alternator

[06KingRanch]

What is a good High Output Alernator? My stock on is on its way out and looking for some feed back on what brand to go with.

DC Power. Without a doubt.

I have a DC Power on my platinum its been great so far. Would definitely be on the top of my list for an alernator .

I have a DC Power Tad-185

I wanted a DC power unit, but ended up with a Mean Green 200 Amp.

Biggest concern I had was the clearance between the discharge piping, and the back of the alternator.

Here are some pix showing the size difference between the stock, and bigger MG case.

I have a large case high output mechman... hand built in the us for less than $200 shipped and 200 amp output... 120 amp at idle

I tried a 200 amp on my truck and it seemed to be overcharging....

I ended updoing a 140amp large 6g case alternator for a two alternator system combined with a smaller ovrdrive pulley. Works way better then my stock alternator. Tried 3 of them and no stocker could keep up. The one now is stock but 140 compared to 100 from the right on for my truck. Combinedwith the smaller pulley it charges nicely at idle even with verything on.

Only problem with running a smaller pulley without having an alternator designed for the extra rpms is that it tends to shorten the life of the alternator.

Yup.
I ran one of Doug's smaller pulleys on my stock alternator...but at 41-4200 rpm...the alternator is spinning at over 12000 rpm.

It no rikey.

And if 4200RPM continuous is a daily occurrence I'd like to work with you.....
