Doubling up York Compressors...

[MT1]

Moorehouse just bought a four door Cherokee for a donor rig. It has been gutted now and in the aftermath I called dibs on his OEM AC unit. Im currently running a York compressor for my on on board air. I have seen where guys double them up and use one for the AC and the other for the OBA. Is there anything that I should be aware of if I do this. Im guessing a single belt for both should work just fine? Or do I need an Idler pully in the mix?

I believe a guy used to make brackets to allow the use of two yorks. One for A/C and one for OBA. I don't remember how it worked.

I think you need to stand the A/C compressor up so that it's in the 'vertical' position. Then use the bolt holes on each side of both compressors and make a bracket to connect them together. Just run a single belt that is just the perfect length with no idler between the two compressors. This is assuming you have already installed two P/S belts and only run a single alternator, A/C belt.

I know nothing about the subject but when I read what you were contemplating, my first thought was to include in the design logic controls that will not let both compressors engage at the same time

I have OBA now and I control it manually with a toggle switch. Thinking this will have to be my "Logic Control" for a while! =)) I wonder if it would put that much drag on the engine if they both were on at the same time? If they both came on at the exact same time I think it might make a difference but if its a staggered start Im not convinced it would matter?

So how did it work out for you? any issues or problems at all? Mine will be going on a SB Chevy but its all about the same I'm sure...

Do ya have any larger pics?

I think it would be cool to have two OBA compressors.

That would really help air up 42" =p~

I'll see what I can do tonight....

Somebody on IFSJA used to make the brackets IIRC but haven't seen them available for awhile now.

I have a V twin York (off my old Dodge van "Fat Albert" former ambulance) that will go in mine for air. Sanden compressor for the AC and intake manifold cooling (LPG injection needs it for hot starts to stop vapor lock)

Oh wow never thought about Vapor Lock issues with LPG... Is that a typical problem?

[carnuck]

only on liquid LPG injected motors.

I was figuring on running a stock idle solenoid modified to fit my holley to bump up the idle when running both.

Sorry guys, it seems I saved them small. They are too distorted to see any detail if I enlarge them.... X(

Thanks, yes that helps quite a bit. I need to find another York and get busy.
