  • 3 CarPC setup in Mustang

    Hi friendly forum folk,
    I am installing three Power Bundle - Mobile Car Computer System $584.99 from the MP3.com store to install in my 07 Mustang.
    Why 3 car PC's?
    I need them, trust me.
    Anyway, I was wondering is there a special 2 battery/2 alternator setup I need to do to run three car PCs or can I do it with just one heavy duty top of the line 12volt battery and my stock alternator?

    Thank you in advance.

    You don't need 3, for anything. But go ahead since it's fun! Your car PCs aren't using very much power, and will not be an issue on the stock charging system.

      Thanks for the info dscustoms!
      You were right about the low power requirements of the motherboards. And it seems I have changed my setup a little.

      2 Power Bundle - Mobile Car Computer System CarPCs
      1 Normal desktop PC with a SOLID STATE drive and and specs similar/same as this:

      cpu: http://www.newegg.com/Product/Produc...82E16819103817

      And a 1000 Watt DC/AC Pure Sine Wave Inverter - 12V to power it: http://www.amazon.com/gp/product/B00...tomotive&psc=1

      Now my question is: Will I still be OK with a one battery setup with this new configuration?
      Thanks again for the help!

        My setup was originally supposed to use 7 computers (I drive an SUV with 6 passenger seats). In the end I went with a system with Dual-Core and 4GB of RAM for the Dual-Zone setup. For the individual computers I went with a single AMD Phenom X6 setup. It basically uses virtual machines and creates 6 different environments. Only issue I am having is assigning USB devices to each VM. If the devices are the same, like all my soundcards, it tries to install all of them on that specific VM. So in short, I have 2 computers creating 8 independent zones.

          I'll recommend again that you review the system specs. What are you planning to do with this? Are you planning on using a desktop power supply with that inverter? You would be better using a mobile DC-DC supply. If you are using a desktop supply, I'd get ONE supply and use it to power all three systems.

            Yeah, I'm puzzled by this, too. 2 computers in a Mustang is overkill because NO ONE wants to be riding in a back seat that small. 1 PC can easily handle two users, especially if one is driving (won't be able to utilize a whole lot, safely).

            3 Computers is your car doesn't even make sense. I really think you are overestimating your needs. I could be wrong, but I just don't see it.

              I agree, my Dual Zone PC is split into two areas, the driver (can only see driver based stuff), and the passengers (see only entertainment stuff). I am using a C2D with 4GB of RAM. I am also using onboard video and PCI based soundcard. I did this to save on power.

              Yes, review the system specs. I know for a fact that the graphics card you plan to use requires over 300 watts to operate. Plus 95 watts for the processor and any USB and other devices will add onto it too. No automotive PSU would be strong enough to use the setup. You would have to use an pure sine wave inverter and a desktop PSU. You will then have to figure out a way to automate the start up and shut down process. The way I am getting around it (my install requires a 550 watt PSU) is that the inverter is controlled by the OPUS 320 automotive PSU via relays. With that said, if the main pc is off, the second pc can not be turned on at all.

              You should really rethink your setup. Trust me, I have wasted tons of money on my install trying to work out all the bugs that goes with a multi pc based install.

                Yeah. I have near the exact same car in all but year and options I believe.

                Aside from the "seriously?" factor this brings to mind, even with kids involved for outfitting, as to your original question, our OEM alternators only do about 75amps at idle and absolute max is like 130. This is assuming the OEM one is in great working order, is working at that limit, and assuming you're not one of the many with one that has issues, or about to crap out completely... Then I'd expect to go through a battery per 6 months as a decent guess IMO with what you plan on.

                My current setup I consider massive overkill, even for a multi-monitor VM setup. I just wanted some future-proofing, no chance of a speed issue for video playback, and I like to cook bacon in my console from the heat generated...


                Opus 360 only...about 40mins is the max before risking flintstoning it home with this (engine left off). Even careful, my average is about a year and a half span for battery life now if I'm lucky. That's 1 PC, the stock factory "Faker 1000" amps, and a 300watt kenwood doing the normal speakers.

                If you're dead set on something like this, then you "might" be able to get away with it, but I would suggest something like a second battery with an isolator. FUBAR a spare, not the means to get home.

                  Wow thanks guys!
                  A lot of useful info!
                  I need 3 Car PCs because I am the guy who made this:


                  I NEED all these PCs to work to do various car functions of the new KITT.

                  The Sine Wave/High End Desktop route is the way to go I think for my graphics intensive PC application.
                  Then the other 2 mini ITX PCs can run off of there respected PSUs.
                  That would work with a 1 battery/alternator setup right? The only difference in working with the Sine Wave Inverter would be I would just have to go to the trunk and start THAT computer manually right?

                    OMFG...

                    I want one. I still think a modern pc could handle that load, if you are using a good graphics card. That's ******* beautiful. I hope you aren't messing with us and using prerecorded sound board clips...

                    OMFG did I say that enough? I need that in my Lexus, asap.

                    Is this a product you are selling? KIRAD ? Have you been playing with this for years?

                    It's freaking cool.

                      How do I get the sine wave inverter to be controlled by the OPUS 320 automotive PSU via relays like you did HiJackZX1?

                      Yeah I have been working on this since KITT project since the show was still on the air.
                      It really works and responds to your voice. No audio tricks at all lol.
                      KIRAD has pictures of him installing one of my orbs in a customer of mines car on his website.
                      KIRAD never claimed that he made my Orb on his website, just installed it.

                      I am almost done with the project and am ready to purchase the main computer components/systems.
                      Your right one modern PC could handle the load of just the Voice Orb. I have one running it already. I need 3 to do what the car does now. (Heads Up display, center screen, Holo Gauges,ect,ect,)

                      I can't go into a lot of the details yet but trust me, I need 3 (2 Mini-ITX and one heavy duty desktop) pcs that can handle some extreme stuff I have been throwing at it and one carPC is not gonna hack it anymore. lol

                        Honest answer then is no. You'd be averaging above what our OEM alternator is capable of replenishing. It's not like audio amps where the draw is dependent upon the feed given. The PC's and peripherals will maintain a fairly constant draw. I'm pretty sure with 2 stronger mini-itx pc's, and full blown desktop even 130amps average wouldn't do it.

                        I'm not sure on where you intend to mount them, but also keep in mind my own issue currently. Airflow. I had to mount a fan in the mini-itx case just for the video-chip's heatsink to keep it under 100 celcius. This is normally sufficient now to keep it at or below where the CPUs are at, but if I actually had a constant significant load on it I'm sure this thing would be shutting down, as the air has very little place to go. As I'm typing this in my car now (from a coffee shop), everything is hovering around 88 celcius, since the fans have nowhere to push the hot air. EDIT: speaking of which, trip to Microcenter just killed it without the AC on. with the newer setup, got over 100, turned on AC, now at 56 after just a mins. Crap on a stick.

                        Short version, mount somewhere where you can easily maintain airflow since you're not installing the normal low-power CPU/GPU pc's.

                        As stated, that's cool as hell, but at the least you'll need a high power alternator replacement. See a 6G at pa-performance.com for our cars. Or have the OEM one rebuilt.

                        Perhaps another will chime in here, but with that and I assume other odds and ends (amps, etc) your likely looking at that not even being enough. Dunno for sure. Likely you'd need to see the actual draw using an ammeter and plan occordingly.

                          If you are going to be drawing a lot of power, you might want to check out some of the competition car audio websites. You might need more than one alternator and more than one battery. As Wayne has already pointed out, you need to do the math and figure out what your equipment is going to need, then make your plan.

                            i understand and respect that your trying to keep some of the details to yourself to prevent copycats (i am in the process of about $500 of led lighting mods to my car), but at the same time, limiting the details that you give us makes it hard to come to any conclusion..

                            can you give us any benchmarks on what kind of processor/graphics power you require for each feature?

                              Well if i am not mistaken, text to speech where the pc has to listen, takes a lot of PC processing power. I doubt that uses much graphic power though. Even then though, you can still go with one PC. Just use one with more cores. My Multizone setup is a Phenom II x6, meaning it has six processor cores, each at 2.8ghz. i then have a virtual machine assigned to each core. Then Each core gets 1024GB of RAM, which is more then enough to run XP. The host is Win 7 64bit with 6GB RAM. Total of 12GB of RAM. So I have six computers in one package.

                              I have to find the diagram for my OPUS 320 and Inverter setup! I'll look for it for you.
