Bags are for Fags tech request

I've got two viair 450c's going into my Bel Air wagon, hooked to two 5 gal 4 port tanks with 1/2" electric valves. Should I run dual alternators and two batterys? Would it be necessary?

One for the cars electrical and one for the compressors & stereo? Or should I just get a big alternator? Also, I hate having relays, could I run power directly from the alternator with a maxi fuse? The car will also have power windows, poppers and power tailgate glass.

Thanks

 

I had to upgrade my alt. to a 140 amp internally regulated unit, got advance auto to price match summit on a chrome powermaster. I run two optima yellow tops wired in parallel. I also wired everything using 2 gauge wiring in the engine compartment, the power wire, and a ground going from the alternator to the frame, and the battery to the frame along with the existing ground to the block. I struggled with that shit for about a month, but I have no problems what so ever now. I'm running an air zenith compressor which draws around 35 amps I think, I have an airlift 450 too, but only run it when I'm playing with them and want a faster fill time. I'm running a 1440 watt amp for my ghetto fabulous stereo too, and I have no more charging issues beside the damn alt. idiot light staying on......Oh yeah, I used 4 gauge wire to connect the front battery to the rear battery and also going to the 200 psi pressure switch. This stuff shouldn't affect any of your power accessories. Hope this helps you out.

 

We have the same type set-up, 2 viar 450's etc. and we didn't do all the changes mentioned in the last post. We put a 100 amp alternator in, and bigger wire from the alternator to the battery and that's all. Inline 30 amp fuses to the compressors, with 12 ga. wire. Haven't had any problems yet. You will want to run the relays though. They take the load off the switches.

 

i would get rid of the viair compressors and find a york a/c compressor, they are cheap at the wreckers, they have their own oil so they dont burn up, they are quiet and have way more cfm. I have run bags on a few cars now and I will never ever use an electric compressor ever again. The only draw back is the motor has to be running to pump air. just my thought, it seems easier than running to alternators and 2 batteries and all that crap

 

I would, but I don't want that massive heap inside the engine compartment. Next time I go air thats the route I'm going. Even onboardair.com has all the brackets for a SBC app.

 

I was told by a air installer that running 2 tanks is not ideal. Says that the compressors will always be running. He suggest 2 compressors with one 5 gal tank. Quick fill

 

Whatever your decision, keep in mind a lot of that stuff (pwr windows, poppers, etc) is only momentary and won't tax the electrical system much. It's the stereo (if it's got a bunch of amps/speakers) and things that are run more constant that matter. Point is, don't overkill the charging system because of a bunch of momentary items. Just rock a good high amp battery and a reasonable alternator. I'll only ASSUME your not in some hopping contest with the airbags.

 

You can find a Sanden a/c compressor. I dont know much about those since i have a york. I have seen them and they are smaller than york but you will need to put an inline oiler on it since it doesnt hold oil like the york.

Electric compressors CAN SUCK A FAT ONE.

those things are noisy and break down alot. I would rather haul around a small nitrogen bottle than listen to those noisy things.

Hope this helps you any!



P.S.
I though people around here didnt like airbags and such.

 

I do alot with airbags.
A ideal set up would be 2 viar 480 compressors or something equal and one 5 gallon tank. You want quick fill with the least amount of wear on your compressors. Also you can run a nitrogen tank with a back up electric air system.

The more air volume you have, (tanks) the more compressors you have to run. On average a viar 480 comp is good for one 3gallon tank without killing it.

 

thanks guys.... so ideally I should run two batterys and a 140 (or bigger) amp alternator then.

 

Sounds like you are set on electric pumps, but I'll chime in anyway. I just put a Sanden on mine, and it is the cat's ass. No comparison at all. Supposedly 8-9 cfm, next to no current draw, and silent. It's fast.

 

I think the best route is to run two hydraulic pumps, 4 accumalators from Parker so you can get that Caddy ride, 2- 6" cylinders in the front, and 2 10" cylinders in the back....and four batteries. You'd be done.

 

Here is a Viair 450-c after only 8 months of daily use.

 

they come with a warranty as long as you run one of their pressure switches.
