On Board Air

[LA_Fred]

Yeah, I did a search. My question is:  anyone running a 12v or 24v compressor like the ones by extreme air or kilby enterprises in their yotas? FROR makes an adapter to use the stock toy ac compressor for air but you lose your AC so I was thinking about going 12 or 24v and mount it somewhere on the body(engine is tight) so that I can have both worlds, ac and air! I believe Foothill offroad also makes an electrical setup for less than the other competitors.
Any info would be great.

you can run both - check out ErikB's setup..

[LA_Fred]

sweet, same ErikB off of PBB right(redrunner)?

I run an Extreme Air.  Foothill Offroad and 4x4 Products makes the same thing now only cheaper.  I mounted mine in the bed with an air tank.  Works well and I still get my A/C.

yep, york compressor with ac

Hey Ferg,
yes this is one of the options I was considering since Foothill claims a continuous duty cycle on their compressor.  How does it compare to an engine driven compressor e.g toy or york? Thanks for the info.

Well heres a quickie write up on my latest MOD.  it's something EVERYONE wants but for the most part its to EXPENSIVE..  Well ladies and Gents  Here it is....

(Drum roll Please) 

This is a DV-Inovation MF-1050 flows 72 Liters per minute.


This unit is NICE, made from STEAL not Pastic


I mounted the unit Beside the Brake Booster on the drivers side.  Bolted it down to the Fender well. Theres enough room to even store the hose

Here is the 4Air System,  Mine is a knock off of the GREAT Roger Brown's Creation.  BUY YOURS from Roger Brown as it will be cheaper for you, and his design is a little better. UNLESS you  order all the pieces in BULK and build one for all of your 4x4 club members.(as we did). Rogers setup is the way to go



Now the fun part.  I can deflate all 4 tires to the EXACT same PSI and go from 31 psi to 9 psi In 2 Minutes and 25 seconds


Close the Valve, hook up the air line, and turn on the Compressor. I can Inflate all 4 Tires from 8psi back to 31 psi in 13 minutes and 48 Seconds. (BTW I have 31" x 10.5 M/T's)

how much was the compressor? I have a powertank but at $10/fill it gets pricey..

$64.99     YOu can find them on ebay for cheaper
Kragen is selling the last of their stock for you US people for $45.99  Its the older model MV-50 but same specs

How fast would you think something like that fill up some 37's from 10 psi to 25-30?  Is there a duty cycle on that thing?

I dunno do the Math 31's from 8 to 31 Psi under 14mins.   so 37's for 10 to 25 maybe 20 Min ?  I dunno.   The unit will overheat ater 45 min or so and shut off.  than kick back in when it gets to a safe temp range.   Apparently The company that made this thing is comming up with a DUAL pump system what will be super fasr.  (I may have to sell mine and pick that one up)     Roger Brown www.4crawler.com  has info somewhere on his page about air compressors and volume and such.

I have a friend that was in the same senario.  One weekend we came up with a way to mount a second pump piggy back to the ac pump.  it was rotary just like the stock one.  The first attempt used one long belt and turned the air pump fine but the ac pump would not catch.  That setup wored for the winter but when summer came my friend decied to try a power steering pully infront of the main pully and with very little modification that has worked well.  he just slid the second pump forward about 3/4" and now both work.  I don't have any pictures but if you just look long enough you will get some ideas, if wasn't really that hard at all.

I'm running a York

I have the Superflow MV50, looks just like the tsunami.  It filled my 4-33x 12.50 AT's from 5-35 psi in about 35-40 minutes w/o a tank.  It is a 100% duty cycle.  Two others in my group one with 35's and the other with 38's took them about the same amount of time, but they only filled their tires to 25 psi(what the noirmally run on the street.)  The litte compressor works great for ARB's as well.  I fab'd up small tank(4"x7" cyl.) and one of the copm's for a buudy, and it takes the compressor about 10 seconds to fill the tank to 100 psi.

Got a Snickers?  Gonna be a while...The air volume of a 37-12.5 x 15 tire is nearly double that of a 31-10.5 x 15 tire.  Inflating the larger tire to a lower pressure would have a significant impact but this has all been calculated on the PowerTank web page for their liquid CO2 systems.  The air compressors should behave proportionally slower.

I filled 7 rigs and two trailers (3 axles total) from 12 psi to road pressure varying between 25 and 55 psi in less than 45 minutes with a 15 lb PowerTank and still had some CO2 left for the welder.  The downside to the PowerTank is the cost of filling, about $10-$12, and the difficulty in knowing how much is left in the tank since it has to be checked by weight.  It is also possible for the safety rupture disk to let go particularly if the tank has been overfilled and subjected to elevated temperatures.  It is unbelievable how much gaseous CO2 comes from a 10# bottle in mere minutes.  The dry ice was 3/4" thick under the dash.  Luckily the vehicle and driver survived the incident and the tank has been relagated to riding in the back of the truck.
