Poor Man's Warn Power plant = Smitty Built 9.5K + SuperFlow MV-90

    I recently bought a SuperFlow MV-90 compressor, which worked really well but is very bulky. So I decided to make a redneck version of the Warn PowerPlant:
    Materials:

    5/8" plate

    1/2" x 1.5" flat stock

    1/4" x 2" flat stock

    2 allen screws

    Here is the process that I used to build the clamp for the handle:

    cut the 5/8" thick plate down to 2"x2.5", drill a 1.5" hole in the center with a hole saw, drilled two holes down the length past the center point of the 5/8" stock, cut the 5/8" stock in half horizontally, drilled out the bottom half of clamp deeper, tapped threads, drilled the top half out with a larger bit so it would clear the threads on the allen screw, then finally drilled a larger hole in the 5/8" stock for the allen screw head to recess down into.

    It looks interesting but cool how does it work?

    works pretty good. I contacted Super Flow to verify that the pump could be mounted on its side, they confirmed that was a good configuration for it. I put some rubber isolators on the bottom plate so it doesn't vibrate too much and reduce the life of the compressor. As far as the mount its self... seems solid and hasn't fallen off yet, made it through the Rubicon last weekend with it.

    Took about 20 minutes to fill up four 37" tires from 12 psi to 35psi, so the volume is pretty good, much better than my old Costco one. Since it is permanently mounted above the winch I just wired it to the winch power and ground, seemed to give it a little more pep since the wires are only 10" long now.

    What about weather durability?  Can it be left outside?

    Time will tell for sure, but it does have rubber grommets for the wire penetrations and a silicon cover for the switch. I put a rubber plug over the air coupler.

    I am still planning on building an aluminum cover to put over the top.

    It is unfortunate that these jeeps don't have enough room in the engine bay for a York 210 compressor, the SuperFlow is nice, but nothing compared to my old York.

    Superflow compressors are really good for the price, i got 5 years out of my last one, but really need to be stored in the vehicle.  They use shielded but not sealed bearings so even mounted under the hood they will only last a year or two with dust intrusion.

    3.6 JKs are packaged tight but there is one kit that allows a York to fit under the hood.  Super tight and pricey but it does exist.  http://offroadonly.com/shop/on-board-air/off-road-only-complete-on-board-air-kit-for-jeep-wrangler-jk-2012-15-2/

    Really? I thought it was just the older superflow models like the mv-50 that were shielded and not sealed. I was relying upon a review article I found that said it was sealed for the mv-90

    Given that it is sold to be kept inside the carrying case and doesn't come with an IP rating, i don't see them spending the extra 10 cents on the better bearings.  But, honestly, no way to know what your unit has unless you pulled it apart and ran the bearing part number.

    Either way, the better it is protected from dust and water the longer it will last.  You are our guinea pig for externally mounting a superflow mv-90.  Keep track of what you do to protect it an how long it lasts.

    I don't think I have ever had a cheap electric Chinese compressor like this last more than 2 years with any kind of consistent use.

    It is certainly sold as a "portable" compressor so it makes sense that it would come with a case or bag. My buddies ARB compressor didn't have an IP rating listed on the box.

    I'll let you guys know when it fails up, might be a while though 🙂

    I guess I could have my wife sew up semi water proof cover(snow mobile seat fabric) for it instead of doing the aluminum shroud

    Pretty cool set up. My long list of projects (most of which I probably will never get to) includes permanently mounting my Smittybilt air pump under the hood of the K5. Plenty of room there. . .

    Cool yeah keep us posted I currently have a mv-160 and love it. If I could hard mount it that would be great.
