RussoGuitar,

Have you had any problems with the output hose getting too hot?
I have read other OBA setups and they either used copper or braided steel hose because of extreme heat, right after the output on the compressor.

Very funny you say that.. Yesterday i gave the system a real work out. After wheelin i aired up 5 jeeps from about 8 psi to 30psi. 3 of vehicles had 33's, one had 34's, and one had 35's So thats 20 large tires with no breaks in between. By the end the hose coming directly off the compressor was so soft from the heat build up that it began to severly deform at the clamp and started to leak. It felt like i could rip it with my hand. It seems that the heat generated by the compressor along with underhodd temps was to much for the hose to handle, so i swapped out the one peice of hose that comes off the compressor for copper tubing. My original plan was coil a length of it to dissapate heat but that was taking to long. After i made this mod i ran the system for about 20 minutes non stop as i wire wheeled the doors on my buddy's jeep. (he took his molding off and i was removing the glue. The copper tubing did its job and the rest of the airline didnt get soft.

Yeah i didnt care about A/C, and my a/c was a pain in the *** to keep it working right anyway. You could get another a/c comp from a junkyard and mount it next to the existing one to retain your ac.. but that was just more work and money for me.

yeah that works, its looks like if i go ahead with my battery relocation and reroute the upper radiator hose i should be able to make some sort or bracket to mount it next to the original AC one

then its a matter of re routing the belt

Yeah that should work... you could eliminate the airbox with a cone style filter, and then mount the battery where the airbox was.

I'm outside slowing working/planning this out. I just need some clarification on a few things...


First, as I'm disconnecting the a/c lines (got it professionally evacuated), what needs to get thrown away? One line coming out of the compressor heads to this box...what is it?





Second, the other line coming out of the compressor travels to the radiator, then thru another hose ending at the black cylinder (bottom right). Can this be removed as well?





Third, there are two wires running off the Sanden, they join each other and turn into a single orange wire. It then travels to the huge wad of wires at the bottom of the pic. Can i simply cut this wire and wire my pressure switch?




Sorry for all the questions, first time for everything. And Id rather learn what all this stuff is than just removing parts and trashing them.

-Chris
