Downeast Johnny Posted February 27, 2013 Report Share Posted February 27, 2013 Ever looked in to a double alternator setup? http://www.highoutputalternator.com/dual_alternator_kits%20with%20load%20share%20module.htm That a serious looking set-up. Have you checked on the price of any of them? I have a DC Power Engineering 300 SPX alternator. 300 amps at about a cruising speed. I don't have electric fans but its on my list of things to do. I also only have a small system put usually have all 3 power ports in use and one running an inverter. It works pretty good and looks great Sent from my DROID RAZR MAXX using Xparent Red Tapatalk 2 Great looking alt. Does it take a longer belt, or stock?

cb2big4u Posted February 27, 2013 Report Share Posted February 27, 2013 Double alternator setup is around a thousand. Which is more than likely not necessary in your case. New high output alternator will take the same belt. My issue with dcpower is they make their highest output at really high rpms. Most of the time higher than the engine can even rev. Like that spx 300 making top output at 6000-8000 rpm. They have a spec sheet on their site. I will be going with mechman. Full amperage at 1800 rpm.

chawkins6789 Posted February 27, 2013 Report Share Posted February 27, 2013 The spx makes it full output low. Look up DC power engineering on YouTube. They have a video of an alternator similar to mine in a bench being tested. Max output is around 2500 rpm. http://www.youtube.com/watch?v=SSILASmW-mg&feature=youtube_gdata_player Sent from my DROID RAZR MAXX using Xparent Red Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
cb2big4u Posted February 27, 2013 Report Share Posted February 27, 2013 (edited) They should prob change their website then because its misleading. I was really dead set on going with them but not anymore. Also is dependent on ratio of crank pulley to alt pulley. We have a 3.2 to 1. Right on with what their online specs say.

chawkins6789 Posted February 27, 2013 Report Share Posted February 27, 2013 With a 3.2 it would make power at a lower RPM. Their numbers for 300 amps at 2500 rpm is based on a 3 to 1 ratio. I put over 350 miles a week on the highway and it works fine running stereo, all my power accessories and 2 sets of HID's Sent from my DROID RAZR MAXX using Xparent Red Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
cb2big4u Posted February 27, 2013 Report Share Posted February 27, 2013 (edited) Their numbers for a 3 to 1 to 3.5 to 1 ratio say 300 amps is achieved at 8000 rpms.... I don't get it.

chawkins6789 Posted February 27, 2013 Report Share Posted February 27, 2013 8000 alternator RPM. At the factory 3.2 ratio it works out to 2500 engine RPM. Sent from my DROID RAZR MAXX using Xparent Red Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

Aldofashow Posted February 28, 2013 Report Share Posted February 28, 2013 Just to add your PCM is made to run the truck at around 14.4 volts if your at 12volts or less I can't imagine it would run perfect Quote Link to comment Share on other sites More sharing options...
