I just looked at their site. Holy crap, $1500 for the "cheap" unit lol. I was/am looking at the Viair 450C IG's. I don't really need it to run air tools, just want a good bit of volume for the horns. And since I have access to the air tanks at a reasonable price, my main issue will be where to mount the tanks.

i seen some engine driven aircon compressors that could be adapted to move air
they where mounted on some types of the older type of volvo's the one you need is selflubricating , it might be a nice add on and have one electric compressor for when the engine doesnt run
maibe a semitruck type engine compressor would work too DAF did fut those to cummins motors and im sure petebilt and others did too

Cummins offers them too, but I refuse to lose my vacuum pump and have to re-engineer my power steering. I know I'm not after a compressor to do service work on the side of the road, the initial fill will be the largest load on the compressor and if I would have to install two on the Mega, it would still be cheaper than an engine mounted compressor or the Oasis. Granted both of those are more efficient than the Viairs.

Thats my debacle. do all the work to run the engine driven, or buy the good electric. im still not decided. if you or your brother dont find me an engine driven by the time i need one, ill probably go electric. and if i can manage it, im getting the oasis. i want to be able to run pit at the derby in style! now, what can i sell...

I can find the engine driven but the price will be close to the Oasis... Found a Cummins part number since I'm bored at work...3558002:$1515.57 Retail price through work...

One thing to keep in mind with the Oasis is the 180ish-200A draw for the lighter duty unit. If you are not mounting it close to the batteries the voltage drop alone will shorten the motor life dramatically. That's the reason I went with an Extreme Outback compresssor. 100% duty cycle and a whole lot less amp draw. Yes, it puts out less air too, but I'm not running air tools on a regular basis off of my truck so that's not a major concern.

Do you have room for a York?? Hell, Autoworld probably has a bolt-on bracket for it. Bang for the buck, it can't be beat. I did not have room or I'd have one on my truck. I was even trying to engineer a pto driven setup that used a York compressor to get it out of the engine compartment, but the time came that I needed OBA and I wasn't far enough along in the engineering process to make it a feasible option so I went electric. A York with a tank on it would allow you to get rid of your shop compressor. LOL.

Just take out one of your injectors and run an air line from there!

Would work better if I took two out so engine still stayed in balance for firing order lol

And you could still out-pull my truck!!

Get to work son!

[1985-GMC]

Don't they make pto driven compressors also?

[ryanroo]

Damn! ill hope for used. at that price i think id rather the ease of the oasis

[jbclassix]

I have a IH 466 belt driven 2 piston tumor you could bolt to the side...

I can keep an eye out for one (any) if you guys keep an eye out for a 4BT saginaw pump for me.

PS pump, or hyd. pump?

Power steering pump. I want to loose the Vacuum pump on my brothers truck all together. I could use the hydraulic pump, but that means custom lines. We are doing a remote reservoir either way.

are you looking for a particular air pump? 2 cyl? 1 cyl?

Edit: I need to look and see what compressor is mounted in our service truck. It is tiny and POWERFULL.

[watahyahknow]

maibe you can do the monster cable setup that most of the audio lunatics use along with a good relay that way the amperage dont get as high , im not sure but using a (good namebrand ) capacitator from the audio setup might help too flattening the startup peakcurrent of the compressor
there accuswitches that are being used in campers mostly that helps charging a second battery on a single altenator and prevents drawing current from the starterbattery to power the interiour lighting when camping so the engine will still start when the other battery is death

[Dieselwrencher]

Oh yeah, for $1500 I'll buy an Ingersoll Rand for the corner of the shop.

[Dieselwrencher]

I may know a guy that might have a saginaw ps pump. I'll call him and see.................

[ryanroo]

Im looking at for a 1 cyl. im not sure ill have room for the BMF

[jbclassix]

I just went all the way back to page 5 to see what you did to get your D80 mounted... the first time. And I am asking both you and Ryanroo this question. If you hypothetically mounted your axles on leaves(not the Ryanroo AirRide), would you build custom mounts to move the springs out further, or would you stick with just moving the spring pads in?

[ryanroo]

Spring pads in. moving the mounts out would put a lot of leverage on the frame and the mount. wider is better, but to do the mounts wider would be way to much work for not uch benefit.

[Dieselwrencher]

On mine, I just cut off the cast mounts, and got some axle perches from DIY4X. I happen to have my rear suspension for sale if you're interested. My DIY4X shackle flip, new springs, D80 spring perches, u-bolts, cast upper retaining plate, D80 lower mount, and front spring hangers. I'd seperate the stuff for sure. If I keep it around, it'll mean I need to put them on something.

[ryanroo]

markets gonna be flooded! i have a custom set of plates U bolts that point up, ballistic pads ground for 4" tubes,some custom ass shackle hangers, and stock front hangers for sale...

We finished up the 02 Dodge job this week, and I've gotten started on my GN and frame. I got the cross members welded in, and boxed in between them. Here are some smokey shots.....






Today I trimmed down the center hitch and notched my front cross member so the center section would fit in there. I sat it in the frame and low and behold the release handle hits the frame. So tomorrow, I'll notch the frame, install a tube to give clearance, and then weld in my lower supports and weld the center plate in.

Also, my brother took the center section to work to sand blast it so it doesn't retain it's dredger look.
