And I would not worry about this as mine did this even when I had taken my system out for a while. I would sit at stop lights and hit the window button just to the the rpms fluctuate lol

I suggest check some of the mk3 threads as this is for mk2's. also if you call ford they'll tell you.

I was hoping the stocker was 110 amp alt. That way it seems I was getting so much more with a 270 amp HO alt.. But if stocker is 150 then im only gaining 120 amps.

Kinda considering only doing a 2200 rms setup now and stick with a 200 amp alt and single 100AH battery.

But was planning on 4000 rms, 270 amp alt, and 2 102AH in trunk.
Yeah, Singer told me to just stick with my stock since it is already 150 amps.

I have two amps, about 1400rms total and with only one shuirken bt-20 I had very little voltage drop. I just recieved a bt45 also that im going to add in and I expect almost no voltage drop.

crice8 I was looking into this a few weeks ago also. When I browsed the web places said the oem one is 110-120. But I talked to singer alts and He checked his sources and he says our stock alt on the 2010 focus is a 150amp alt! I was going to order a HO also but he didn't have a case that would fit our model.
