Mostly what it said. Yep on the mud forum is doing a group buy on these little air compressors that are really a good value. You can read about them on a couple of the links. you can buy them locally for around 70 at pep boys. He looks to have gotten it down so far for about 42 plus shipping. I personally have not had one, but I have liked all the reviews I have read about. According to the reviews they have been holding up well, will fill tires in a resionable amount of time. A national mag rated them real well.
Mostly I wanted to give a head up, I have order a couple for my self to have if needed as a back up to the CO tank, for the wife's car.
He is placing the order on monday and will not take requests after that to buy in on this order. later robbie

Thanks for the heads up, Robbie, will have to look into getting one or two of those. Great backup for the CO2, good to toss in the other car, use for filling up bike tires & footballs etc. ;)

Robbie can you give us the link to that thread. I did a quick search on mud and only found an old thread. I want one.

I assume you are talking about the MV-1050 unit. I am running two of them hardmounted in the Chili with the front bumper utilized as an air tank. They work just fine. The quality is not bad at all, especially considering my money went to building Chinese nuclear submarines:eek: .

They are a little heat-sensitive being in the engine bay, and if running one by itself it overheats and shuts down before completing the fourth tire. Running two in parallel kicks but and rivals CO2 time however, plus, you have redundancy in case of failure. I also carry a third one as a mobile unit in the other trucks. I thought of mounting them in the side panels in the rear, but couldn't come up with a good system.

Not to rub it in or anything (yeah, right), but I paid $25/each on closeout at Checkers. Checkers figured they weren't selling because they didn't plug into the cig lighter (!!!!). SO they dropped the price and they started breaking Mach 1 out the door once people knew they existed.

Dumb Checker advertising execs...

Wow Bill , sounds like you were way ahead of us. I think I'll change my order to two. I like the idea of hard mounting them.

Well the sudden influx of RS guys has caused Yep to close the order. Funny how that happens. Any hoo I can not wait for them to come and play with some set up for the truck. While I like the CO tank, the electric pumps will be great for those long trips north or south of the borders ( and a few trips inside as well). Thanks bill for shareing your experence for these little guys. later robbie

Wow Bill , sounds like you were way ahead of us. I think I'll change my order to two. I like the idea of hard mounting them.

I found a couple other things of interest. The hose quick connect fitting is nonstandard, interestingly the very same as the ARB 'quick' (yeah, right) fill kit. I tossed that so I could use my shop standard. You can use barb fittings to adapt 1/8" NPT fittings to the fill hose if you like the fill hose/deflator arrangement (works pretty well). I used the pressure gauge on a Tee fitting in the fill line to see the tire pressure (they are pretty accurate, if a little light on resolution - 5 lb. increments), and left another on a Tee hardmounted to see the system pressure. I then put a 1/8" NPT ball valve so I could shut off the fill and read the tire pressure without disconnecting anything else.

Some of the fittings on the compressor are 1/4" NPT and pretty painless to adapt to hardmounted lines. Some are not; they are pretty close to 1/8" NPT but not quite (I think they are not NPT, but straight threads, with the fittings held in place via red Locktite). I prefer the sealing qualities of tapered threads, so I forced- um, let me say, 'persuaded' 1.8" NPT fittings onto / into these fittings. Examples would be, the output port, and the pressure gauge male end/ gauge female port (which is functionally the same as the output port, I took the head off - O-ring gasket - and examined it, so you can have a side output if that suits you better).

If you are not into forcing things, picking up an 1/8" and 1/4" NPT tap set is the solution, but not really needed. Threadlocker is. You might need a tap for a bumper 'air tank' if you do what I did, using a rubber air hose and threaded barb fitting to fit it.

I think the part number for the rubber isolators is 17853-35010, a rubber bushing with 8mm studs protruding both sides. You will need some nylock nuts for these (cheaper almost anywhere but Toyota). Pop out the rubber feet from the air compressor and replace with these. Don't hold me to it, but I do think that's it.

Oh, I almost forgot. Be sure to test the compressor before hardmounting it. I had one that decided to not work after I mounted it, this enabled me to discover that one compressor under the hood is a little susceptible to thermal shutdown... :o I unmounted it, disassembled it, and fixed an intermittent on the on/off switch. Oh, and I left the switches in place for selective shutdown if needed for whatever reason. You could elect to remove them.

Use a fatter gauge wire than what comes with the compressors, and you will have less voltage drop. CarQuest carries the appropriate relays (12V, 30A) and bases (I think a headlight socket, actually!) for the relays. Radio Shack carries just the relays. They are available elsewhere on a hit-and-miss basis.

So how do people like these?

I thought it was quite slow. I aired up yesterday from 15-35psi on my 33's. I knew it would be slower that co2, but it took about 5x as long per tire. Seems like it took as long as a little ARB compressor.

It will be fine as a backup I suppose.

That's why I put two hardmounted under the hood... that, and the fact I have this thing for redundant systems. I use my front bumper as an air tank. Works pretty spiffy, makes no more noise than the old ARB did, has a LOT more capacity, and is only slightly slower than the CO2 tank-

AND! No global warming greenhouse gases, and no taking up room in the back of the truck neither, as well, also!!!

(I got a little tired of rough-weather camping and putting my leg against a COLD CO2 tank in the middle of the night, especially pronghorn hunting. And bumping my head on it. And getting caught on the regulator whilst snaking around back there for some thing or other I'd lost track of on a trip. And the additional weight of the tank. And bicyclists in Moab thinking I ran NOS or something.)
To be honest though, I didn't mind how long one took. I'm usually jawing around that time anywho. Jeff seemed to mind, but I didn't.

Hahaha!!! Here's a story: So last summer, we're done with the ground survey of Jenny Creek, right? We'd just dropped the FS off at their truck, good time to air up. So me and Perry both air up using CO2, the SAME CO2 tank mind you.. then look back and Bill's still on tire #3, little compressor chugging away while he's talking to these guys in an old white CJ. "Slightly slower than CO2" may be an understatement here, though a big part of that is the operator. :D

That's the reason I never bought one. I think i could have pulled out my bike floor pump and beat bill. Maybe bill doesn't mind but it seemed like we were there for 1/2 and hour. I need that time on the road as slow as I am.. :eek: :D

Ok, so I'll conclude about 5 min. w\co2 and 15-20min with this little pump. It will be used as a backup only.

You know me, unlike Bill, I'm usually in a hurry to get aired up and back home near the pre-quoted wife time.

Yep, I got mine primarily for backup, in case I run out of CO2. And if the day comes when I'm not in hurry to air up & get going I could always save the CO2 for another time I guess.

Actually, I prefer ale and steak.

and the one thing I don't have is a brake. Almost every other implement of destruction, but no brake. yet. I need more shop/studio space before I get anymore tools.

I learned to carry a spare compressor even with co2. I once limped about 40 miles on 10psi, on the highway, in vernal. ick

I would say... that would be a Scotty from Star Trek estimate. Should cover any and all situations. I NEVER was able to get aired up in 5 minutes with my CO2 tank, and don't seem to recall taking 20 minutes with my dual compressor setup. I would say for me, 10 minutes CO2, 12-14 minutes dual compressors.

Single compressor, yeah, you're about right on the 20 minutes. And on a hot day with the compressor in the sun or under the hood (even when open), you'll trip the thermal breaker on tire #3. 'Course, the Chili mill pumps out some BTUs, YMMV. I do not experience this with two compressors with the hood open.

'Course, I've run out of CO2 a few times at about that point, too many times. CO2 and the compressor makes an MRS (Morgan-Redundant-Systems) compliant configuration. I just got tired of having a near-useless ARB compressor, AND a CO2 bottle. I didn't want to go the other way and possibly lose lockers AND air-up capability with a single failure, so I went with dual compressors - for $50 plus wiring plus hoses, clamps, connectors, and relays. This way I get redundancy but no bottle taking up interior space. I moved my tools and spares into the side panels for the same reason, and got a nice carpeted sidepanel to boot.

It may not comply with Mrs. (Missus) $tandards though.

Hardee har har.

IIRC I was still leisurely breaking out the hoses when you guys were 1/2 done with one truck. And yeah, I think I got home before you did anywho...:p

That was what I did for a while until I was confident of my compressor setup. After a while, I got tired of hauling the bottle up and back.

The Chili and I are on a modest weight reduction program. I'm having more success than the Chili is, so the bottle was an easy decision.
