Reminded me of WWEST and his skill... that is him in the blue pants. LOL Like alittle piss ant or a pesky knat.

I'm married, have been for 50 years....

exactly. I like mine full blast as cold as it can get. Even in a modern car. Guess when youre as old as dirt like WWEST you cant handle the breeze.

So since your wife doesn't like it cold in the car, you think that no one does?

As do I. I have never thought the a/c in any car was too cold.

No one likes to be discomforted, hot, cold, humid, what have you....

And it's not a matter of not liking it COLD, it's a matter of discomfort due to cool and dry airflow being directed to a persons face and upper body hour upon hour.

Take a look at how the 996/997 system redirects airflow once the cabin nears or reaches the temperature setpoint.

[brads911sc]

No car I have ever been in was too cold. No car has ever provided discomfort. Sorry wwest. Why don't you run along to the early bird special.

I would not want a system that auto directed the airflow away from where I have it aimed , so the 996/997 system is a step in the wrong direction if that is what it does.

And we're to assume that you are a perfect "John Q Public" insofar as human comfort is concerned...??

NOT!

And you and your wife are?

[brads911sc]

You are missing the point wwest. Ac systems should be built to be great for the most demanding. Everyone else can turn it down. Designing a system so the old ladies (you) are happy will not work for 90% of the population. You are welcome to bring a sweater or shaw.

[kuehl]

Oh, So Willy wants the perfect system for a 911/930 that can satisfy anyone, anywhere.

Well, lets see if we can keep that thought in line with the context of the OP.


Easy:

1) An R134a system since it is the more easy to find refrigerant that can be serviced just about anywhere. You could use R12, rather expensive though. Other alternatives can give you problems if you need to have the system serviced. So, R134a is the way to go.
2) Kuehl Barrier hoses to reduce refrigerant permeation leaks; if you have an o-ring system then new o-rings.
3) Kuehl binary low high pressure switch to protect the system.
4) Kuehl drier, to start things off fresh
5) If you have an SC, discard the York, use a Kuehl 507. If you have a Carrera then inspect the pistons, bores, wobble plate and bearings, shaft. If all looks well then a seal kit. If things don't look good or are questionable, use a new Denso 10P15C. Use ester oil.
6) Evaporator upgrade with the Kuehl unit since it out performs OEM and all competitors. The Kuehl unit is more reliable as well and comes with all the bells and whistles you need to do a proper R&R.
7) Since the SC and Carreras are short on condenser capacity, depending upon your climate and driving needs, you might start off with adding the Kuehl rearward (behind the left hand rear tire) fender condenser. Again, depending upon vehicle needs and climate possibly add the Duehl Kuehl in line with is cousin, or simply the Kuehl serpentine front condenser. Which combination of them all is a factor of car color, type (coupe, cab, targa), number of occupants and climate.
8) Since the SC's lack enough ac air volume, add the Kuehl Center Vent or possibly
the Tri-Kuehl Vent system. With Carreras simply adding the Kuehl Center unit is enjoyable (beats having wasted ac air dump on the floor or hit the back of the console).
9) Fine tuning ac can be achieved with the Kuehl Variable Speed Fan controller, any speed you want, combined with your desired thermostat setting you will enjoy the ride. And the Kuehl Indicator Light let's you know the system is on and when the comp clutch should be engaging (aka thermostat has a demand).
10) Put it all together and you have a reliable winning system to enjoy the most driving days per year. Kuehl systems come with the most detailed installation instructions found anywhere as well as above normal tech support and sound warranty.

Bait, line and sinker, lol.

Agreed.

2) Kuehl Barrier hoses to reduce refrigerant permeation leaks; if you have an o-ring system then new o-rings.

Or in the alternative use some method, or methods, to prevent the pressure on the high side from exceeding the point, >400 PSI, wherein our legacy hoses really begin to leak>

Kuehl suggests a binary switch which is most certainly a good start. But then a method is still required to prevent pressure rise due to loss of cooling and/or heating effects from the engine. Using a trinary switch to power fans (front blower, cabin heater, or even add-on fans), 24/7 would be the perfect answer.

3) Kuehl binary low high pressure switch to protect the system.

Waste of money. You can install a trinary switch for the same money and effort..even if you don't see the benefit now you will eventually.

4) Kuehl drier, to start things off fresh

Or the exact same drier from the original manufacturer, no Kuehl "relabel", for about 1/3 the cost.

5) If you have an SC, discard the York, use a Kuehl 507.

Kuehl 507.. would someone please remove the Kuehl "relabel" and tell us what lies underneath..?

If you have a Carrera then inspect the pistons, bores, wobble plate and bearings, shaft.

If all looks well then a seal kit.

Yes, by all means, let's start fixing things that aren't broke. Better yet use the trinary switch and fans to prevent seal "breakage" due to excessive system pressures.

If things don't look good or are questionable, use a new Denso 10P15C. Use ester oil.

"Look good..??

6) Evaporator upgrade with the Kuehl unit since it out performs OEM and all competitors.

Yes, but is the kuehl <1% performance improvement worth the $600 cost vs the Rennaire evaporator for only $300.00 ??

The Kuehl unit is more reliable as well and comes with all the bells and whistles you need to do a proper R&R.

More reliable..? By what, whose standard....?? What bells and whistles that are not provded by your competition at 1/2 the price..??

7) Since the SC and Carreras are short on condenser capacity, depending upon your climate and driving needs, you might start off with adding the Kuehl rearward (behind the left hand rear tire) fender condenser.

Yes, by all means, "click here for quote", fill out the form and wait for an answer.

http://www.griffiths.com/shop/index.php?main_page=product_info&cPath=15_16_17_19_67&products_id=87

Or you could go to Rennaire (sorry..ZIMs) and purchase their higher performance (doesn't require 2) fender condenser/fan assembly for all of $500.00.

Again, depending upon vehicle needs and climate possibly add the Duehl Kuehl in line with is cousin,

Like I said, it takes 2..and the cost is....

or simply the Kuehl serpentine front condenser.

Yes, by all means, buy/install the Kuehl front condenser and thereby LOWER your refrigerant condensing capability.

Which combination of them all is a factor of car color, type (coupe, cab, targa), number of occupants and climate.

8) Since the SC's lack enough ac air volume, add the Kuehl Center Vent or possibly
the Tri-Kuehl Vent system.

Or, if increasing system airflow is the issue, simply remove the "bowtie".

With Carreras simply adding the Kuehl Center unit is enjoyable

But becomes seriously discomforting for the average Joe or Jane within minutes.

(beats having wasted ac air dump on the floor or hit the back of the console).

Wasted in what sense..? No conditioned airflow that enters the cabin is "wasted".

9) Fine tuning ac can be achieved with the Kuehl Variable Speed Fan controller, any speed you want, combined with your desired thermostat setting you will enjoy the ride.

Or, if you are into electronics, or like a slightly challenging DIY, you can get the same capability for $20.




And the Kuehl Indicator Light let's you know the system is on and when the comp clutch should be engaging (aka thermostat has a demand).

But be sure it comes with a damping diode to install directly across the compressor clutch coil, else always wear eye protective glasses.

10) Put it all together and you have a reliable winning system to enjoy the most driving days per year. Kuehl systems come with the most detailed installation instructions found anywhere as well as above normal tech support and sound warranty.

Bait, line and sinker, lol.

He says that 78 degrees is cool enough.

Nonsense, on a stick. 78 degrees is too warm for me in a car. I like it COOL in there - 70 degrees, or even a little less. My wife likes it at 70. But not much lower. We often compromise at 70. When our house gets to be 78 degrees inside, we start turning on the AC to cool it down. My max in the house is 74 degrees.

His idiotic idea that EVERYONE wants 78 degrees is so dumb as to be forehead-slapping in the world of dumb.

Rennaire doesn't make a fender unit. Get your facts straight...
