Default Warn SPI Air Compressor

Anybody see or use one of these beasts yet? If so, how do you like it? How do you have it mounted and wired?

I ordered one sight unseen and am starting to think about how to mount and wire it. I was thinking of using the monkey fist clamps to hold it down in the back while on the trail and mounting a heavy duty Anderson power connector to the front bumper somewhere. When it's time for air, plug it in and go.

It's back ordered so I have a while to think about it.

I got the demensions on them about a month ago. I think it will fit on the wheel well in front of the roll bar in my 4D with a fabricated platform. It shouldn't touch the back seat. I've already relocated my muffler and plan on putting an air tank where the the original was.

I haven't heard a price yet or found out where to order them. Where are you getting yours?

Quadratec has the SPI listed for $599. I ordered mine from there, but like I said, it's back ordered.

What are the dimensions? I have an email into Warn tech support to get the current requirements. The dimensions and current should be in the manual, but apparently they're not.

I'm in a two door. I didn't think about mounting mine on the wheel well, but that's a great place to put the compressor and keep the cargo area in the back clear. My thought was to set it in the rear floor board behind the passenger seat and keep it transportable between my vehicles.

I have the file on another computer, but I think the SPI is 15" long, 8" wide, and 11" high or there abouts without the carrying handles. The space between the roll bar and the back seat is the limiting factor. It's 17" in the 4d.

They are kind of proud of it as far as price. The other one I was considering was the ExtremeAire for not quite $200 less. But I think I'd like the warn.

About as proud as they are of their synthetic winch line.

The ExtremeAire has a free-flow rate of 3CFM. The Warn has 3.5CFM flow rate at 90PSI and a 1/3 gallon reservoir. The Warn is probably worth the extra $200 for the reservoir and extra flow rate for me since I don't plan on running an auxiliary tank. Of course since you plan on installing an aux tank, these probably aren't as big of issues for you.

Thanks for the approximate dimensions. I'll post the current ratings when they get back to me.

Hi All,

I just received the unit and unboxed it. Initial reviews: DISAPPOINTED

First off, the unit is MADE IN CHINA. If I had known that, I would not have bought it. I hate to return it to Northridge, but may if the cost is not too steep.

That being said, it looks nice and seems very well designed. The electric motor that runs the pump is larger than most auto starter motors.

Out of the box, the power cables (about 6 feet long) have eyelet connectors on them, so you can not simply hook it up to use. I'll get some high current quick connects and then try it.

DO NOT buy the Powerplant accessory kit. It is made in Taiwan and is of very poor quality. The hose is a hard plastic, the air gauge came with free corrosion. This *is not* worth the $100 - not by a long shot. Maybe $25. I could have purchased a Made In USA hose and gauge for the same money.

I'll post a full review when I get to play with it

I did use them during Trail Jamb in July last year. They filled the 35's quicker than my on board set-up. Warn had them on with battery jumping cables and they are noisy as expected, alittle quieter than a powerplant.

Not to resurrect an old thread, but I wanted to update the info for search purposes.

OK, I've lived with this unit for 6 months and will give a review. In short - it is great. I was deeply concerned when I first received as as it was made in China - not usually a source for high quality products. In reality, except for a few screws that loosened up all the time (I had to Lock-Tite them), it has held up well. I can go from 18PSI to 37PSI in less than a minute (32" tires). It can run an impact wrench to take off lugs, though you need an efficient (high quality) gun to do so. Every time I take it out to air up, everyone wants to use it. I attached clamps to the power cables to allow me to connect it quickly. It has a 100 percent duty cycle, so no need to let it rest between tires.

Oh, and it is the same compressor the PowerPlant uses.
