My Mark 4 Airride Build...

[Chaoz]

id still definitely add another down the road. i hated the sound of my compressor
the 444 is 100% duty cycle tho, so it doesnt really need time to cool down between use. if you got a compressor with a 33% duty cycle or something like that id be worried about only having 1

yea im still learning about all this lol but, yea i think ill start with just the one to see how it goes thanks sir.

[jettaaddictionII]

Nice! what management are you planning on going with? (sorry im too lazy to look up and read haha) Definitely 2 compressors are the way to go. It's so much more convenient and so much less of a hassle. Definitely worth the extra few bucks.

just good ol' basic manual management with paddle valaves. nothin to fancy

yea, im probably going to go with either 2 400c's or 2 380c's. the price for them are practically the same.

May i suggest 1 ob2 instead of a dual 400 or dual 380 setup?

between 380's or 400's i would go with the 380's because of the duty cycle, 380's dont need cool down time. But like MechEng said about the ob2, i kinda wish i would have know better and got one.

[jettaaddictionII]

hey sir

May i suggest 1 ob2 instead of a dual 400 or dual 380 setup?

one of those is more expensive then 2 of the other ones, either the 380s or 400s, and the the backup of the second will be alright.

oh alright. i didnt know that, i just assumed the higher number, meant that it would be better, even though the 380 is 100% duty cycle, and the 400 is 33% duty cycle. Didnt kiddie rose say it would be better to run two of the 33% rather then one of the 100%??

Don't get deceived into thinking that a 444 has a 100% duty cycle at the pressures you will be running, it is only 100% duty cycle UP TO 100psi, after that it starts to drop off. The only compressor that is 100% duty cycle for our pressures that we are running (145, 175 or 200) is the OB2. Plus it only costs $50 more than a dual pack of anything else and is very similar in amperage draw compared to a dual pack and fills quicker and runs cooler. Zero downsides

I have never even heard of a failure on an ob2, but if it does fail the compressors are fully rebuildable piece by piece for a very reasonable price, compared to just throwing a viair away. Check above for more arguements

And yes it is your vehicle, your choice completely

[kilimats]

^ damn this compressor looks amazing !

I'll prob get that one when my VIAR 444c dies, wonder how much faster it will be, hopefully not louder !

[Kiddie Rimzo]

noooooooo. 100% duty all the way!

[jettaaddictionII]

noooooooo. 100% duty all the way!

ok cool.i must have mis-understood what you wrote. my bad

[jettaaddictionII]

^ damn this compressor looks amazing !

!

it defiantly does, ill have to keep that in mind when im ready to get one hopefully next week. And that, the OB2 , id only have to run one of them, correct. rather then two of the 400c's?

and.... everything ordered, other then the comps. which obviously im still deciding on.



and, it would be soo cool if it came o tuesday, that being my birthday

yes zeniths are the ****. I already had a vlair die out on me. When I get around to having a real job Ill upgrade to zeniths

oh really? thats good to know. Are you running dual comps?

[MechEngg]

oh really? thats good to know. Are you running dual comps?

Yup you would only have to run 1 of those OB2's and they outperform ALL of the dual viair compressor packs by far and probably be more reliable also with a 2 year warranty

[jettaaddictionII]

that sounds like a plan.

I don't understand how 1xOB2 could be faster than 2x444c, the CFM is almost the same

I am running dual 400's right now. that was drastically better than the single on. I can't imagine what dual zeniths would be like.

I had dual last summer, ill let you know how triple goes

same haha! And yes! you should take a video for the fill cycle from empty and low with those!

[Chaoz]

i think we will be gettin our setups at the same time lol but, i keep hearin that im goin to need to run dual 444c's im lookin for another already lol

[Twilliams83]

you dont "need" it. will it be a quicker fill, yeah but you will live with one.

[Chaoz]

haha sorry yea thats what i meant. lol

[Twilliams83]

haha sorry yea thats what i meant. lol

if i were you and you i would just get one ob2.

[Chaoz]

if i were you and you i would just get one ob2.

one ob2 is better than dual 444c's?

[Twilliams83]

one ob2 is better than dual 444c's?

i dont quite understand all the numbers that go into it, but from what i take from mecheng, yes.

ahhh well i wanna see how the 444c holds up for me at first. lol

[Kiddie Rimzo]

viairs arnt complete **** like people are making them out to be. between my buddy and I the 450s i had lasted 2+ years (may still be going...not sure since i sold it)

Okay if you look at the numbers, the OB2 keeps a higher CFM rating at a higher psi. What you are looking for isn't necessarily the number, but the total volume under the CFM/psi curve. The area under the curve is far larger for a single OB2 than dual 444's. Check out Martin's link for fill time comparison....
@100psi the OB2 is 16% higher output
@150psi the OB2 is 13% higher output
@200psi the OB2 is 30% higher output

one ob2 is better than dual 444c's?

For fill time yes. Other than that it is all opinions

viairs arnt complete **** like people are making them out to be. between my buddy and I the 450s i had lasted 2+ years (may still be going...not sure since i sold it)

Nope they aren't complete crap, just not as good as the AZ's IMO

[Kiddie Rimzo]

Nope they aren't complete crap, just not as good as the AZ's IMO

i definitely agree...just everyone is making it seem like he made a bad purchase!
i cant even imagine your setup with 3 compressors ha.

[Shoopz]

Yeah what's the fill time with three ob2's. Must be sick
