Air conditioning?, Do they have a/c? Options

[Jackhartjr]

Another silly question!
Does the 914 have air conditioning?

[theer]

A/c was a dealer installed option. So, yes, some did have that installed.

The installation involves cutting a big hole in the front trunk (where the spare tire usually is), for the condenser, running lines down the sides to the compressor on the motor (more cutting of sheet metal to make it fit) and a big air handler unit inside the car. Fairly invasive procedure, and the compressor robs power from an already underpowered motor.


Most have been removed in the mean time. However, plenty of folks on here still run a/c.

See link below, this is the most popular unit installed. Some folk are installing newer more modern units.

What about installing an electric unit out of an electric or hybrid car like a Prius or Leaf? That should have most of the parts you need right?
I don't know jack about AC work, so I am reaching here but I know hybrids and electric cars do not have engine driven AC systems...

[bmtrnavsky]

Something like these Tesla units? https://www.ebay.com/bhp/electric-ac-compressor that price is right... no idea what other parts you would need but that's usually the expensive piece. If anyone else is interested in this I am SUPER interested in figuring this out. its HOT in Texas!

Edit:
What about something like this? How on earth do you install this?

This would fit in a modified center console.

As far as Electric compressors go, the electric cars do not run on 12V. You need a 12v compressor, like the benling one.
https://chinabenling.en.alibaba.com/

Note this compressor takes 40amps to run, plus the evaporator fan, plus the condensor fan. Classic air makes a 911 kit and they recommend a 911 3.2 90 amp alternator at a minimum.

Most of the Hybrid or E-Car stuff is high voltage (48v+)

That Classic retrofit product does seem like a viable answer to add A/C

I agree, between the classic retrofit compressor and southern air evaporator and condenser, you could easily build a system. The only issue is the alternator. I have a 3.2 six, so my alternator is fine. I’m hoping to get an AC system working in my car by next summer.

We live near DFW airport, and my wife's 914 has working air. The stock under dash system used r12 and a huge York compressor that sucked the power out of the motor. Converting to a rotary compressor and R134a will get a working system that is fairly good. Adding a 911SC condenser and a couple of fans to the underside of the engine lid and running it in series with the dealer installed condenser, plus replacing the fan on the dealer installed condenser will make the AC work great.

The 4 cylinder stock alternator can't keep up with the load imposed by a 12v electric compressor. It just doesn't make the amps to support a electric compressor.

There is a thread on here that describes how to make an evaporator to replace the fresh air blower. 914 In Dash Evaporator. I plan on doing that to my 4.0L six. I am going to use an electric compressor, but the 964 engine my 4.0 is based on has a 180amp alternator, so it will handle the load.

Clay, curious how that evaporator will work in Texas since it cannot recirculate air.
Even in so cal, I have to recirculate the air in my daily driver rice rocket to cool the car in the summer.

I think he left out the re circulation function on it. It is in the drawing, but I don't see it in the actual unit.

I was going to work it into my version of it.

There is a recirculation duct on the evaporator I built. You can see it in this photo of the evaporator module installed in the car, but before the gas tank is re-installed:



The duct is the 3" black hose wound with white reinforcing cord to the right of the evaporator box itself. It draws air from above the driver's feet and is always open as a source for the air blown through the evaporator coil, unlike the outside air vent, which has a damper that can be closed. There is room to add a similar duct on the passenger's side as well, which is something I've been considering doing in order to get a bit more air flow.

[Jackhartjr]

Thanks for the replies folks!

I have an A/C unit for sale, removed from a ‘73 1.8, if anyone is interested. You’ll need new lines. (IMG:style_emoticons/default/santa_smiley.gif) yt

[914rrr]

I think this thread has one of the best ideas for mounting a new style Sanden compressor: on top of the fan shroud, like the factory did with smog pumps...

http://www.914world.com/bbs2/index.php?sho...=192917&hl=

I still think there are better places / ways to mount the evaporator, like the rear wheel well(s), or a circular evaporator coil under the spare tire using the factory body plugs.

I get it ,that a 914 can get hot in the summer .

But air conditioning in an air cooled porsche ?

I replaced the York boat anchor in my DPD system with a rotary compressor. Also did modern barrier hoses, flushed entire system, kept it R12. You can hang meat in there it gets so cold and the rotary compressor robs only minimal HP.

Living in the Tampa Bay Area in Florida, it's almost a necessity. Back in the late 90's I had a DD 74 2.0 with a DPD AC system (with the York compressor and R12). Bought it with the system installed and working. That AC system blew ice cubes and was immensely appreciated while stuck in rush hour traffic. It wasn't that big of a drag on the engine. The engine never overheated, even with a single carb setup and I simply turned off the AC if I needed to pass, etc.

I also had a DD 70 911T coupe with dealer installed VPC AC. That AC system was marginal at best and only really blew cold while underway over 40 mph.

You don't live in Texas. When it is 105 outside, and the basket weave seats will leave 3rd degree burns in the back of your legs, you WANT a/c.

[GeorgeRud]

As we get older, our tolerance for heat goes down and AC is appreciated more. A friend’s 914 2.0 with the dealer installed air worked quite well back in the day as the 914 does have a rather small cabin compared to a 911.
