misterp Posted August 28, 2006 Report Share Posted August 28, 2006 Question for you parts counter guys, has GM made a dual or secondary alternator bracket for the LSx/LQx engine, so the truck can be equipped with dual alternators (like the Ford F350 dual alt option)? If so can you reply with the part numbers and info required to do this to the SS, I have to upgrade my charging system and it looks like a single HO alternator will not be able to provide enough current, I'm going to have to run dual alternators and hopefully The General has a bracket somewhere in inventory I can leverage and it won't look or perform like crap. OR if anyone knows of an LSx/LQx specific aftermarket bracket, that might do as well. Thanks gents - Mr. P. Quote Link to comment Share on other sites More sharing options...
tawss04 Posted August 28, 2006 Report Share Posted August 28, 2006 The only truck that I know of the has that option is th Duramax. The only up grade for any gas engine is dual batteries. Quote Link to comment Share on other sites More sharing options...

04CHASE Posted August 28, 2006 Report Share Posted August 28, 2006 you need something like this?? Quote Link to comment Share on other sites More sharing options...
misterp Posted August 28, 2006 Author Report Share Posted August 28, 2006 (edited) Thanks gents, yeah Chase I really like that bracket/idler. I'm only shooting for only half that much current though. 900A, sheesus that's like 12-15KW of amplification! Mr. P.

04CHASE Posted August 28, 2006 Report Share Posted August 28, 2006 they both benched 315 amps on that hoe, supposodly he has 17.5 k watts. Quote Link to comment Share on other sites More sharing options...
misterp Posted August 29, 2006 Author Report Share Posted August 29, 2006 (edited) Well hell then maybe I don't need as much alternator as I first thought; I have an Orion 8004 and Orion 2500D (that's 3200W RMS, ~4500W peak). The two amps have three 100A fused power leads so I just figured I needed 300A for the amplifiers, 145A for the truck (lights, engine, AC, etc), plus some extra for safety's sake and that totals 480A of current so I was thinking two 240A alternators running in parallel? Sound about right to you guys? Or is that under/over kill? The Iraggi Amputator can put out 180A at idle, with two of them that's 360A capacity, meaning I could run the engine, A/C, and deathmatch the stereo on a high-idle. I think? But if I could do it on a single 320A HO alternator then hey that's money back in my pocket... Mr. P.

04CHASE Posted August 29, 2006 Report Share Posted August 29, 2006 i think a nice 300 amp alt would do you just fine, i had a tahoe before this and i had about 3000+ watts with a matts 2400 amp ( ot pulled alot of amps trust me) the 145 amp just didnt cut it at all. and it did the job fine with a 240 amp.

d_a_n_payne Posted August 29, 2006 Report Share Posted August 29, 2006 Im gonna be runnin an Orion 2500d and Im just gonna build up the current alt as much as possible and the put an isolator in....im gonna put the yellowtop in the back with beside the system....the guy said that goin that route would be the smarter move....

fuganator Posted August 29, 2006 Report Share Posted August 29, 2006 I am putting together an spl truck with 4 kx2500.1s and when I talked to stinger about an alternator, they said a 300 amp would be fine to charge the batteries and keep the voltage up. And those amps draw a ton of power. Quote Link to comment Share on other sites More sharing options...

d_a_n_payne Posted August 29, 2006 Report Share Posted August 29, 2006 I think it mainly matters that the batteries are charged....when the amp pulls hard, I dont think it really matters what the alt is, to an extent...the amps will just pull a lot out of the batteries and then your alt is there to fill em back up....I might be wrong....
