Oh, now it's about DISCOMFORT, and not the absolute temperature of the interior. Another moving of the goalposts by wwest.

And to think that ANYONE could be discomforted by the stock 911 AC system.

LMAO. Heck, even with Griff's stuff, my car is acceptable. I think I spent exactly the right amount of money, LOL.

WAIT! I'm supposed to have buyer's remorse, right? The only remorse I have is that I had to get filthy to change out the stuff.

OK, I've been a little sarcastic in this thread,. but let me be completely serious for a moment.

I have written installation instructions for automotive parts before. More than once. I have taken pictures, and offered helpful hints.

Kuehl's instructions are better than what I wrote. If I were to find fault, it would be ONLY that there are fewer photos than I would like. Now, this is personal preference - the written instructions are so comprehensive that *photos are not necessary.* Let me repeat this. You could install the GTI stuff without any reference photos. Easily.

This is unprecedented in the aftermarket industry, IME. Most folks work on the hardware, sell it, and expect the customer and his mechanic to figure stuff out. Not Charlie. He sells you good stuff, then writes excellent instructions AND then holds your hand over the phone.

None of the stupid lies that wwest tells will change that. You want quality product, excellent support and true DIY? Even for the mechanically shy? Spend some money and go with Griff.

Want to waste money and wish you had listened to me in the first place? Take wwest's advice.

Do it.

Do it now.

Wwest= buyers remorse. 100% of the time.

I agree with Eric on written materials. With Rennaire you get a bunch of parts in a box. Doesn't come with any written material at all. It's night and day to what you get with GTI.

I was totally blown away by the instructions. I thought what I wrote was detailed and descriptive. Kuehl sets the bar very high here.

If I ever write DIY instructions again, Charlie's documentation will be the template I follow.

Done, Thanks.

....

I smell urine like I do at my 80 year old dad's house.

Griff never tells you about that part. I had to get under my car and everything to change out the hose.

Also, NOW my two piston Sanden 507 has simply been re-labeled to a kuehl 507 stupid five piston?

This is why Willy has too much time on his hands:

Right = 68-72 degree cabin temps and lowest possible humidity.

Pretty similar to me, however, I prefer it much cooler in the house, particularly for sleeping, so I use a window unit, in addition to central air, to cool my room as much as possible (I also use a mattress chiller). I really am living in the wrong part of the country! :)

Yes, and I am now in the process of "flunking" retirement...

So, that means when you 'officially' retire .... you are going to be funking bored.

I really have no skin in this game, I don't own a Griffith's system but please stop making this claim. This calculation is totally invalid. You cannot use this method to calculate the efficiency of a heat exchanger. Latent heat is amount of heat released as gas condenses at constant temperature (or absorbed as liquid evaporates) and the ratio of the vallues for 2 different chemicals is totally unreleted to heat transfer efficiency. The efficiency is only related to the amount Btus that can be moved from the fluid on one side of heat exchanger to the other. This is a function of the surface area of the heat exchanger and the heat transfer coefficients of the materials involved. Latent heat has nothing to do with it.

Everything wwest says is bogus.

Then why not bless us with the correct method of relating the heat transfer charactoristics of (liquid) water vs R-134a as a refrigerant gas..??

But doesn't the latent heat value/number correlate to heat transfer charactoristics of a "chemical".

Maybe this will help you understand..
