The hell of it is... John's kit is not just limited to the W113 SL cars...

I hope John gets more of these kits in stock soon.

I'm in the wrong line of work...knew the hydraulic crimper//recovery system etc was a good idea

I did the typical Man Thing and completely tooled up to do custom auto AC work on the side for ~$400.
...ended up with 2 recovery systems, almost new $$$$ Welch vacuum pump and 2 scales
(all bought dead, cheap, I fixed/rebuilt, also scored a good Inficon sniffer, 3 channel temp gauge and nice Zeppelin gauge set)
Paid for itself on the first car I did (mine) vs. just having lines made/crimped locally.
Maybe after I retire.

Piledriver,

I am kind of following you in your footsteps. I already had the manifold gauges, but from the post you see I now have a crimper, and I got a good deal on a yellow jacket vacuum pump (comes in Thursday). As far as the crimpers and the pump, They will pay for themselves on this build. Next will be a sniffer, and recovery system. Right now my F250 has a small A/C leak. After what I have learned while building this system, I would be hard pressed to take it into a shop.

Well finally got the AC in and working. Took it for a spin two days ago when it was 104ᴼ, and my AC thermometer measured 38ᴼ while going down the freeway. It was downright cold. It’s ironic that two shops that specialize in custom AC systems told me that I wouldn't have enough cooling unless I ran R12. Ran into some issues along the way, my thanks to Tram and Ed at Gilmore’s for the help. Here are some pictures for your enjoyment.

Trunk area, the lines for my unit didn't quite match up with the existing holes, so I had to enlarge them. All hoses are going through grommets, I just had to fill up the gaps with the same stuff that you seal the fenders with.

Sorry, blurry, my shop camera is dying.

When I got the lines to the engine compartment, I wanted them secured. So I whipped some L brackets up, riveted them to the body and the line clamps bolt to them.

Of course, you have to have the fill ports.

The finished evaporator with gauges. Luckily the evaporator had a reinforcement plate on the bottom to support a radio. This gave me some "meat" to attach my gauges.

So the AC works great, but the engine has proven to be a problem. With the 40DCNFs, I could not get it to run hardly at all at anything approaching idle speed. The consensus I got from talking with some engine gurus was: with my cam and the large barrel carbs, I probably did not have a high enough air velocity to keep the engine going (CRAP).

I still had the ICTs that I had pulled off, so I threw them on thinking they would work - WRONG. The idle still drops, but the car is un-drivable. At 1st I blamed it on the AC, so I drove it without the AC, same problems (hesitation on acceleration). Why had they worked great before, and not now? I then remembered that when I switched to the DCNFs, I also went to a larger set of valve in the heads, and a higher CR.

After a lot of testing and swapping, I've come to the conclusion that the accelerator squirt dumps too much too fast. So I have some accelerator pump jets coming from Pierce Manifolds. If you need weber parts, they have them.

I will also need to rig up some sort of fast idle solenoid. The AC drops the RPMs about 300, then when you put the auto in D, it is even lower. So for now, it looks like I may be stuck with my ICTs. I really want the DCNFs back, but the semester starts in two weeks and I am out of time.

Nice work! The Type 4 (and I think the late Bus) had a vacuum operated solenoid for raising the idle speed, but I don't know much about it.

Edit -- never mind, I see you've mentioned it in the other thread.

Find a JY Mk1 rabbit/Cabriolet with CIS. or ~any other VW of that era with AC.
(there are probably many others makes/models of that era that have the part or equivalent)
It has a fixed AC 12v air valve that kicked on with the compressor, bumps the idle airflow.
Cheap. Simple. Very Effective.
There was a second idle valve next to it that the computer PWM controlled.
Both are useful.

Also, try upping your initial timing, will help the sag, requires simple internal distributor tweakage, usually no need to take it apart, can be done via the access popout.

I posted a detailed how-to on STF ages ago...back when I still fired through a distributor, now it just houses a missing tooth wheel and a hall sensor, and tells me what hole I'm on when checking valve adjustment.

Thanks for the tips piledriver. It's probably not the best solution, but I picked up an electronic solenoid for the throttle. I am actually running pretty high initial advance. Even though the engine is a T4, I am running a modified T1, 028 distributer on manifold vacuum. So I am getting about 8 degrees more initial advance this way. Even though the RPMs are dropping by about 300, if I pull the vacuum line from the distributer, its game over. I will be making the solenoid bracket today and my jets should be here as well. So I am hoping that by the end of the day it will be safely drivable.

The real bummer though is not being able to use my DCNFs after all of the work I put into them. I don't know, maybe its time to get a wideband.

Well everything is buttoned up and working great. The first thing I had to do was to get the jetting right on the carbs without the A/C on. I had previously ran these ICTs on this motor, so I thought they would be just a bolt on affair - wrong. I had dropped a valve seat, so the heads got rebuilt, which meant slightly larger valves and a raise in compression from fly cutting the heads, since I last ran them. However, I would have never thought that going from 39.3mm to 40mm on the intakes and 33mm to 36mm on the exhausts, plus a change in CR from 8.1 to 8.5 would make such a dramatic change in jetting on this mild of an engine. It was just too rich to accelerate promptly from a stop.

I ended up going down two sizes on the idles, plus going to the smallest size accelerator nozzle that they make. Ones the engine was running correctly sans A/C, then I had to make it work with the A/C on. I got an Idle Stop Solenoid for an 1979-86 Rochester Quadrajet Carburetor.

I reshaped the bottom just a little bit, then I bolted it to the case at a through bolt with just the bottom hole. It fit perfectly with no rocking or movement. I did have to grind about half of the adjusting head down, to get a little more clearance from the carb linkage. On the carb linkage itself, I got a long 8mm bolt and cut the head off. Inserted it in the bottom hole of the linkage and double nutted it into place. I then started the engine, put the trans into drive (with e-brake and blocks) and adjusted the solenoid stopper until the engine would just idle at 650 RPM. That is the highest stall speed that I could get.

I then grab some 1" X 1/8 band iron, and bent a 90ᴼ bend in it. Made a couple of slotted holes on top, and drilled a 5/16" hole to mount it to the case through bolt.

This is my mount for the kick down switch. I then installed the kick down switch, and adjusted it so that it would actuate just before wide open throttle. Here is the completed assembly of both the idle solenoid and the kick down switch.

Looking back, there are two things that I would like to change. 1st, I would like to have a torque converter with a higher stall speed. According to the numbers, I am running a bus TC right now, so I would need to get one custom made. 2nd, I wish I could have used a vacuum idle stop. The one area, that the engine doesn't operate at a desired RPM with the A/C on is at idle in neutral. I had to set the idle solenoid so that the engine would idle right while in gear, but when you put the trans in neutral, the engine idles a little bit too high for my liking. I believe with a vacuum unit, it would compensate for this. However, all in all, it was well worth the work.

Nice.

Given the design of the shifter, you could run a loop and put a switch or a separate air valve for the trans load in that enables or disables as needed in neutral or park.

Its not like you really spend any time in neutral though.

Look at all that room with a Type 4 and DCNF's!

Hey Clatter, time for some Berg velocity stacks for those 44s.

IMHO, the DCNFs are about the perfect carb for this engine swap. With all of this room, you don't have to run the tiny little air cleaners. However, the down side is that there is not a lot of information on jetting floating around, so You are on your own. Linkage is another obstacle to over come. For me, Pearce Manifolds was not only a wealth of info, but they tend to carry Weber parts that others don't.

MMmmm.. Yes, lovely..

Is that motor in the stock location?
Seems like more room than there 'should be' for some reason..

Not to totally hijack..


To the OP:
Why did you not try and rig up the DCNFs, again?
Seems that all of the tweaks you did for the ICTs woulda allowed you to run the DCNFs..

This is one of those totally ah Crap moments.

In part I never finished this thread, in part I had a design failure. At the end of this thread, I had pulled off my DCNFs, and went back to ICTs, because I couldn't get the DCNFs to work right. Why I had so much carburation problems was do to a total failure of the auto trans vacuum modulator. While the car was sitting, and getting the AC put on, the modulator decided to die. So I was literally sucking the ATF out of the trans, thus throwing any jetting out the window. I discovered this when the trans staring slipping in all gears. Checked the level and it was way low - head scratching moment. Pulled the vacuum line off of the modulator, and I had a large quantity of ATF on the ground. Swapped out the modulator, put the DCNFs back on and all was great until a couple of weeks ago.

When I built my AC system, I put a rather large fan on the condenser.

I thought that the spare wheel well would protect it from damage, but I was wrong. I pulled into a parking slot at a slight angle, and heard an unfamiliar crunch. I had hit the fan section on the parking stop. It looks like it only tweaked the condenser a little, but it destroyed the fan. So my new game plan is to use two small fans instead of one large one. Not looking forward to it, because it is a royal pain. However, the summer heat is coming on and my only other car options are my non AC type 1s. Will post pitures as I do the swap.

Haven't had any luck finding a similar evaporator faceplate. Curious where you found yours?

We just bought a 71 VW Squareback that we're going to put an AC in, we live in Dallas so no AC is not viable for very long.

[Multi69s]

Just so we are on the same page, and no insult intended, do you mean the in car component (evaporator), or the radiator shroud (condenser)? I might have a condenser shroud laying around, but my extra evaporator is in really sorry shape, and I am keeping it for backup switches and relays.

However, talk to Ed at Gilmore Enterprises. He now has AC systems for the Type 3s. He is a great guy, and that's where I got my compressor and mounting brackets from.

Just thought I’d pass along an update on buying the bulk roll of barrier hose on amazon:
It still works!

I got my 100’ roll of #10 barrier hose today from amazon for a shipped total of...... $4.47.
