TO A/C or not to A/C air conditioing, Should I keep the a/c unit or not Options

[southernmost914]

thanks steve i do not no much about a/c this might be stupid but what is the reciever/dryer and where is it located.
thanks

Canister in the front trunk with sight glass. It stores extra refrigerant, absorbs moisture and is one tool (the sight glass) to dail the correct refrigerant charge.

Zambezi, I would also love to see your compressor mount.

You may also look at hot rod shops to find AC components. Hotrod air and Sourthern Rods both sell the components. JoeO

I've recently corresponded with Ed at Gillmore Enterprises. He stated he is a couple of weeks away from completing an entire 914 A/C system. Since he already has the compressor part done (compressor, pulley, bracket, belt and hardware) I ordered it to install when I put in my new engine. He has compressor components for both the stock Type IV cooling and Jake Raby's DTM cooling. Before next summer I will pick up the rest of the his system which I can hook up to the aready-installed compressor.

What is compressor displacement? Would like to know.

O.K. JC and Joe,
Here are the pics of my A/C project. My car was also bought new with A/C but the engine was changed to a 2 liter and the sheetmetal and all compressor mountings were discarded. So my car then had all the A/C components except the compressor. So I started looking at my options and I did not like the after market's approach. I figured if I could mount the compressor up top with a front mounted pulley like the smog pump set up it would make changing belts and filling with freon much easier. Well I happened to find on ebay a pulley that mounts to the front of the fan. It is cast metal and balanced, so it should work just right. I don't know what it is from. It could be a bus item or maybe a 411 or 412 VW? I don't think it is a Porsche item but it works for what I need. Now with that item found I needed to get a Sanden 508 to test fit for belt alignment. Once I had the compressor I put it where I wanted it be and found that the oil filler is just barely in the way. I could have left it but removing the filler cap and servicing the A/C system would have been tight. So I built a riser for the oil filler with some scrap 1 1/4 pipe I had. I made it so it angles the filler back and up away from the back side of the compressor. Next comes the actual mounting. I wanted an easy adjusting system so I borrowed the idea from the 944, 928 models and used a turnbuckle adjuster. I probably could have stole one from the 944 power steering pump and it might have been the right length, but no time to go looking for one so I made one with a turnbuckle bought from a hardware store. I cut the turnbuckle in the middle and shortened it to the length I needed and welded everything back up (included side gussets to support the turnbuckle). I welded larger nuts on the ends of the threaded portions of the turnbuckle to act as my mounting points. The mount for the fixed end of the compressor is a simple flat plate with 4 ear tabs underneath that bolt through the 4 center mounts of the fan shroud. Welded on top of that plate is the pivot bracket for the compressor.
Now with everything mounted I must say everything clears just fine and there is enough room to work on the system. I don't even have to disassemble the front fan to change any belts now. I also don't have to butcher any of the side tins or the engine shelf. The two holes by the battery box for the hoses were already there and have been there since 1973. I hope this makes sense to you guys.

Those first two pics show the pulley and what it looks like when mounted. Sorry about the fact that it is in the car. The mock up would have gone much fast out of the car. These next pics show the oil filler riser I had to make.

[zambezi]

These next pics show the adjuster bracket and the pivot bracket. I don't have a pic of the pivot bracket unmounted but I think you can still see how it is made

[zambezi]

another of the pivot bracket

Now a couple of the compressor mounted

[zambezi]

In my earlier post I mentioned also changing the condenser fan. Here is a picture of why and the replacement for comparison. I had said it was a 5 inch fan originally but actually put a tape to it and have to apologize... it is actually a wopping 8 inches. The replacement is 13 inches and pushes a whole lot more air.

[zambezi]

Another area of concern was the hole that was butchered by the dealership upon install of the front condenser. Here is a pic of the butchered hole and the clean cut reinforced hole now up front. The large area in the rear is for the condenser which sits at a slight angle and the small rectangle to the front of the hole is for the air intake. There is a factory scoop which will mount underneath and direct the air up into the box which surrounds the condenser and then the fan will blow down exiting the hot air out the bottom or the car. I have some mesh grill material I will attach to the underside also to prevent any ingress of debris and to prevent rock damage to the condenser. I also put to use the unused space to the right of the condenser box for the forward mounted fuel pump. That area is just dead space so now I have good access to the pump and filter also.

[zambezi]

My last pic here is the scoop that will go in the front to direct the air into the condenser box. I am still putting the A/C system together so I don't have everything wrapped up yet but I think you can get an idea where it is going.

[Joe Owensby]

Very nice. Thanks for sharing. I may see if I can come up with one of those pulleys and try that type of mounting. JoeO

[southernmost914]

Zambezi,
Pretty work. All I am saying is you do not need a large displacement pump for such a small area. I also wanted to mount my compressor like that(912E) but I had what I had. Also , not to be a dick but I will put the fan you have have on the condenser when mine fails and not availble . The pitch of the blades and the factory veturi might have better CFM's Did you have a drop in head pressure? Thats what means something.

Is he finaly going to get this off the ground? I have heard good stuff about his product and have vbeen lurking in the sidelines to see what develops. I'm in the Central Valley as you are and AC is almost a necessity during our summer.
Thanks for the heads-up!

ok i found some post what compressor should i get the sander 508 or the sander 510. what the difference. thanks

contact IceAC in California and buy the kit for a Type IV from them. It is a true bolt-On replacement.

Clay
I went to IceAC website and did not see anything mentioned about a kit for the type IV. VW, yes, 911, yes, but no mention of thr type IV. Is this something that I should email them direct about? Or, is this a new product that is not up on their website yet?
TIA

Yeah, it seems like every few months we get an update and it's getting closer but not quite there. His e-mail from 10/15 states: "I am within couple of weeks of finishing a complete ac system for the 914. I also have a condenser assembly for the system that is last major piece to be tested for the 914 ac." I was optimistic enough to send payment for the compressor so I can mount it on my soon-to-be-installed motor.

Steve in Key West, I'll ask what the capacity is and post it.

[jc914]

zambezi Thanks for all the info. great job on the a/c

Steve,
Just heard back from Ed at Gillmore. The compressor is a 7 cubic inch 5 piston rotary type and uses approximately 1.5 hp.

Steve,
Thanks for the follow through. That would be a Sanden 507 wich is a 5 piston swash plate design, not a true rotory. It would be great if some one would develop a type 4 kit with a true rotory similar to that used on Hondas and Toyotas ect. (IMG:style_emoticons/default/biggrin.gif)

Thanks,
