DubNDodge Posted January 22, 2013 Report Share Posted January 22, 2013 I am curious to what the most draw on the stock alternator that there has been. Trying to decide if I can get away with just upgrading batteries for now, and get a H/O alternator down the road. Plus I think it would be cool to see what the biggest system on stock alternator has been. Try to include: Amps put out by the stock alternator The batteries used What amplifiers Voltage drop while going full tilt If the big 3 (4,5 etc) has been done If there has been multiple runs of 1/0 Any other information that would that would be beneficial to know would be great.

purplesyrup Posted January 22, 2013 Report Share Posted January 22, 2013 Im going to contribute, but do not have all of the data your asking for. Stock alternator : 150 amps Battery: Die Hard stock size for car Amp: Crescendo BC3500d Big 3: NO Wiring: 300amp fuse- 1 run of 1/0 and one run of 4 ga. (when I was running the 1/0, I said well hell, might as well leave the 4ga there and use it. more copper=better The highest clamp I have done was 2100w which im sure is all my electrical system can support. Now at the same time, I did not clamp it at any frequency below 40hz, so it could likely be higher on a 35 hz tone around the tuning of the barrel. Note: When I first got the amp, I had only the 4 ga for 2 days, and was waiting on my 1/0 to show up in the mail, I also only had a 125 amp fuse on the amp, I could not pop the fuse, the wire would not let enough current go through to allow the amp to blow it. So technically the amp could have only produce approx. around 1,500w tops off that wire and 125 amp fuse. So, so far, off of my stock electrical, leaving voltage drop out, if i go based off of 12.5v, I've carried approx 168 amps to the amp. then if I went based off of an idle at 13.8, thats approx 152 amps. (again leaving out voltage drop) So in my theory, and very little recorded data, I can tell pretty accurately that I only get about as many amps as my alternator can produce back to the amp. Edit: Also, I am in the process of picking out battery power and a 300amp alternator for this season, Link to comment Share on other sites More sharing options...

But still, running 3500w off stock electrical is pretty awesome, even if your not getting full power out of it. iirc I saw someone on here that was running around 5k, but had like 2 or 3 xs batteries.

Yea man, my first step is getting a 120lb northstar battery, Im working on that now, I will see what that bastard puts out then, the battery is 7000-8000 cranking amps. I ran one back in the day. We will see hwo much better that is, then go for the alt. Im kinda doing this one step at a time to have the enjoyment of watching the increases, and testing, I like to piddle around.
