Colorado B.S. Thread

I used to run a Viar 400p. I feel the air up times were on the slower side of average. It did its job hundreds of times without complaint often doing more than one vehicle. It is/was reliable, no frills air. I rant the portable version and only recently sold it to switch to a hard mount. Racing an MV50 I found it completed 4 tires just as the MV50 completed 3. Racing a modded MV50 the finish was almost equal.

I carried CO2 forever and used to use that for fill-ups. It is way too fast and a waste if you are running with guys who air up with compressors. Typical results was 4 tires filled up before their 1st tire was filled. I'm getting my bottle re-certified to run again though, it does help when re-seating beads.

My new "hard mount" compressor is an ARB. I have not aired up with it yet. It is the large single piston version, not the baller twin. I'm making the switch to hard mount because I don't want to store it in the cabin anymore, if I had a truck I would stay with the 400p

 

I do. Not the greatest, because I'm driving. I'll get them off my phone and post up here soon.

 

Stimandli!

 

Thank you for your input. Always appreciated and respected.

Maybe this is the case with all compressors, but my MV50 gets scorching hot after filling two 31" tires from 18 to 35 psi. After three tires I can cook an egg on it, after four tires we set up chairs around it as if it's a campfire.

I usually let it rest for a few minutes between tires 2 and 3 but yesterday I was in no mood to sit around getting shellacked by hail.

 

That's a lot of hippie labor.

 

Look at the specs, it's cfm is almost the same as the Arb twin.


6.2 cfm Arb twin
5.3 cfm northern tool
2.5cfm mv50

 

my 2 cents is ARB, either Single or Twin.

 

No doubt it dwarfs the MV50. I was commenting on the MV90 which has 3.71 CFM output.

 

The 400p would boil water that would hit the cylinder head. Just seems normal for those little things.

 

Well my little $40

$91 viair 88P portable compressor kit (12V, 120 psi, forup to 33" tires)

viair 88P was only behind the $500 arb twin by maybe 3 minutes total. Both on 33's. My baby viair will fill up my 33's from 10-35 psi in 4-5 minutes per tire. Not lighting fast, but nearly keeps up with things 10X it's price.

 

I think you remember this wrong, even the box side stats say this is wrong. Unless you had significally more air pressure in your tires already than said ARB tire ones.

 

I see where you are going with this, but anecdotally I have had the same experience as Asher. When airing up with my cheap compressor I dont seem to lag far behind people using an ARB twin. Im with you that it doesnt make sense based on the stats, but that has been my experience. Definitely not 2.5x slower or whatever the CFM rates would suggest.

 

Wow if that's accurate, you have fantastic results.

I suppose if my MV50 is still going and will only be a few minutes behind bigger hard mount compressors... might as well keep it until it dies.

Although I swear Old Brett's smittybuilt inflated my tires much more quickly. Very noticeably so.

 

I challenge anyone to prove me wrong with their fancy arb!

 

I might blow your doors off with all the pressure I will be throwing!

 

@Madjik_Man Running a Viair 400H (Hardmount) Same thing as 400P but without the handle and the deck plate. I run it with an "air it up system" hose that works on filling all 4 tires at one time. Got it from Edge Automotive. It's nice airing up all 4 at once and leaves you time to BS as it does it's work. Not to mention all 4 tires inflate to the exact same pressure. I also have a CO2 tank for those crappy moments when I need to get done quickly. Also CO2 is good for re-seating beads or running air tools.

 

Thanks Gramps.

 

Just a couple of pics so far. I really am absurdly lazy when it comes to these things.

Coming down from Tin Cup Pass summit, on the east side:




Camping atop FR 295 just below the trailhead for Hancock Lake. That's Mt Pomeroy in the background



Heading up 277 to Baldwin Lake. Fun trail. Mostly mellow, very bumpy, narrow and steep. Soft shoulders in the beginning climb which also coincide with a steep shelf. Got to the junction of where you can continue on to Baldwin Lake or head east on the Mt Antero trail. But it was torrential rain and hail. Not to mention around 4pm and I was looking for a spot to camp. So we headed back down and ended up driving to Cottonwood Pass and camping there on a less traveled FR.



This is a pic from the hike up to the east portal of the Alpine Tunnel. If you look closely you can see (I believe to be) the Mt Antero trail.

 

Anyone here slide off a trail around Rollinsville? The rescue recovery is going up there for a 2012 Tacoma. I was thinking of offering up but I'm not cut for my tires yet. If it someone here I'll respond though.
