At what speed relative to the engine does the 964 turbo spin the fan..?

I'm going to have to assume that at this point you are simply joking around - no other explanation I can think of for the absurdity of what you wrote . . .

wwest doesnt know. he really doesnt know. hopefully he can dream up a new theory by tomorrow. lol

WHAT???

Now he's claiming that this so-called gas-phase cavitation happens at engine fan speeds???

Supposedly, by the link I was sent, this happens only when a turbine spins at tens of thousands of RPM. Of course, that assumes that one citation in a car forum and nowhere else, anywhere, constitutes evidence that cavitation occurs in the gas phase.

Compressor stall? He has no idea what's even going on there, physically. It doesn't have any relation to blower fans or engine fans. He makes it up as he goes, inserting big words he finds on the internet. Only an idiot would take anything he says seriously.

"Turbine stall."..? Don't know if I've even ever seen the term, let alone made use of it.

Compressor stall, yes.

You seem to accept cavitation as a legit term...in the very same context yet...

[wwest]

And here we have both Jim Sims, post #9, and...Kuehl, post #10, both seemingly accepting the "cavitation" term as legit. Also a context of interest to us.

It's great to see the turboencabulator is still in use after all these years Good stuff , keep it coming!

Good for you - you found an old thread where I made a mistaken post within it (I said in it that the 993TT used a curved blade fan, which is false, as it uses the straight blade fan) - I amended the post and admitted my mistake. Thanks for calling that to my attention.

YEP TRIPPLE DIGIT AMBIENT TEMPS ALL OVER THE USA TODAY THE 911 OWNERS USING MY PFC’s ALL HAVE 30 DEGREE 911 A/C
If you think it’s hot now just wait it’s going to get even hotter this this summer setting new high temp recorders all over the USA and world

If you’re interested in a real 911 A/C new technology very cold PFC solution private message me


The stupidity and ignorance of the majority of the recent posters to my tread I make Parallel Flow Micro-Channel Condensers for 911's front and rear REALLY CRACKS ME UP!!! It’s the blind leading the blind AND OTHER IDIOTS the same people posting here also posts in all the A/C THREADS HERE. This sadness makes any of us that are knowledgeable related to 911 A/C SYSTEMS SAY NOTHING TO AVOID THE BS FROM THE IDIOTS.

Keep your posts on topic to this tread or don’t post here; GO START YOUR OWN THREAD ELSEWARE IF YOU REFUSE TO BE AN ADULT!!

It is really sad that the majority of the posters here Are Very Disrespectful and must act like children

[KelogGes]

FYI FAN Mentality JUST POSTED HERE is pure stupidity related to making an early model 911 A/C System cold & is shear lunacy LOL
Pull your rear deck lid condenser off your deck lid, go to Home Depot or other hardware store that sells heating/air conditioning lengths of insulation or weather stripping and buy some for only a couple of dollars. Attach your chosen insulation to your deck lid around the outer edge of the inside of the deck lid thick enough so when you re-attach your rear condenser is completely sealed to the intake air opening so all incoming air is FIRST FORCED “ONLY THROUGH YOUR CONDENSER” WITH NO AIR ALLOWED TO GO AROUND THE EDGES SO THAT YOUR HUGE 911 ENGINE DRIVEN COOLING FAN HANDLES ALL AIR INTAKE AND COOLING. This very simple a/c modification will greatly improve the efficiency of your rear main a/c condenser far better than any fan you could try to add for the rear condenser, unless you just like wasting your time and money


REGARDING Retroaire’s reference and picture
HEAT EXCHANGER “MULTI-FLOW” TECHNOLOGY IS OVER 10 YEAR OLD TECHNOLOGY FROM THE R-12 DAYS AND IS PRE PFC MICRO-CHANNEL PARALLEL FLOW R134A TECHNOLOGY! Notice there is no reference to R134A and only R-12 in the picture.

FACT MICRO-CHANNEL TECHNOLOGY TUBE Extrusions Inventions ARE THE HIGHEST KEY For the most efficient A/C heat exchanger designs IN THE WORLD TODAY!!!!

THERE ARE NEW ALMOST DAILY MICRO-CHANNEL TECHNOLOGY TUBE Extrusions Inventions being invented and made available, so fast it is nearly impossible to keep up with the very latest state of the art of the micro-channel extrusion tubes to say the least in my design changes. But fortunately I can adapt very quickly and change my designs because I can change anytime I want because I do not rely on others for manufacturing changes.

These MICRO-CHANNEL TECHNOLOGY TUBE Extrusions are why the “Surface Area on a PFC” with state of the art PF TUBE Extrusions are what allows the PFC to ACHIEVE A 25-35 percent smaller in physical surface area dimensions footprint AND STILL BE ABLE TO HAVE AN INCREASED 30-45 percent greater heat exchanger Efficiency which is GREATER THAN 10 YEAR OLD MULTI-PASS A/C TECHNOLOGY. For anyone stuck in touting obsolete serpentine or other technologies or older micro-channel technologies THAT ARE COMPLETELY PROHIBITED FROM THIS CAPABILITY BY TECHNOLOGY DESIGN LIMITATIONS, you’re an ignorant fool AND REFUSE TO BELIEVE SCIENTIFIC FACT AND/OR EVERY NEW AUTOMOTIVE A/C SYSTEM ENGINEERING DESIGNER IN THE WORLD TODAY OF ALL THE MAJOR MANUFACTURES.


Retroaire as a reference ROFLMAO, how ignorant to modern fact.

Retroaire is clueless to say the least, this Retroaire very obsolete web picture example was found on the internet and was posted by its original author about 10 plus years plus ago, notice it only talks about “PASSES”

YET SAYS NOTHING ABOUT THE HEAT EXCHANGER TUBE technology used for the passes DUH!!! Or even what kind of heat exchanger it is and the reason is because Retroaire has no clue.

Retroaire’s claim to fame is they were the first to put A GENERIC UNIVERSAL Parallel Flow technology a/c condenser in an old Jaguar replacing a Jaguar’s Tube and Fin technology OEM condenser when they found a generic universal fit a/c PF condenser that would fit SUPPLIED BY ACKITS.COM (ALTHOUGH NOT PERFECTLY) in front of the radiator. Then they expanded their product line a bit due to their success with the Jaguar they put one in when they added A GENERIC UNIVERSAL Parallel Flow technology a/c condenser in an early model 911 deck lid replacing the 911 Behr rear condenser tube and fin technology with a PF old technology condenser that was a poor deck lid fit too small and not curved to fit the deck 911 deck lid contours. A few years ago when they posted their results on the Jag and on the 911, I looked very carefully at the pictures in their test and it was easy for me to ID the supplier of their generic universal condensers and out of curiosity I ordered one from their supplier and meticulously tested it on my 75 Carrera; yep its far better than the Porsche Behr OEM’s, but its performance and efficiency really sucked as well as the technology used in it. If anyone wants it let me know it’s in my rejected test components trash bin and useless to me and was the last straw before I started making my own state of the art PFC’s.

I have spent a lot of time carefully evaluating and testing all the 911 heat exchanger aftermarket & OEM products available before getting angry how much they suck using their old obsolete technology and designs before I decided to finally engineer, design and make my own front and rear matched set state of the art high technology PFC’s specifically for early model 911’s because I could not buy what I wanted anywhere in the world for my 1975 Carrera. When I started to get extremely serious to make my 911 A/C using R134A VERY COLD and successfully accomplished this engineering task using my new technology heat exchanger designs with a 30 degree A/C system in 95 degree ambient temps I had no intension to make them for others.

But only after accomplishing my original goal beyond my expectations with my heat exchanger PFC’s I started getting further into the early model 911 A/C system other components and developed a new technology evaporator and other new ways to control the refrigerant which now has led to several discoveries and new inventions unknown to anyone for a complete early model 911 A/C redesign that is a new discovery redesigned new early model 911 A/C SYSTEM that is very cost effective and overcomes ALL PORSCHE A/C FLAWS, unfortunately I will not make this available for the DIY !

[KelogGes]

Let me enlighten you about Retroaire and the condensers they sell to their unsuspecting customers and where they buy/get them from and what they are! GRIN, this is info they do not want you to know BECAUSE you can buy the same low tech PFC condenser they sell as theirs from ACKITS.com for only $136. They are GENERIC LOW TECH PFC’s that come in many UNIVERSAL dimension SIZES. Go to ACKITS.com Automotive Air Conditioning Parts & Equipment.
ACKITS.com Automotive Air Conditioning Parts & Equipment.: Parallel Flow Condensers - High End Aluminum

hint Look at the ackits.com universal FSHE PF Condensers that will almost fit the inside of your deck lid air opening but too small


then go to Retroaire web site and look closely at their pictures if you can find them and compare them to ackits.com universal , if you cannot find Retroaire’s rear condenser picture on their web site do a Google search for retroair Porsche condenser test and you should be able to find a picture of their rear deck lid condensers

BTW Retroaire’s 911 $200 front serpentine obsolete technology is made in China

Related to the 911 aftermarket A/C component contenders I consider everything Retroaire sells is subpar, but whatever floats your boat

Regarding Rennaire I think their pro-cooler is a waste of money, yes it does sort of work to give only a couple of degrees only colder vent temp. everyone I know that professionally works on Porsches for a living and there are several I know for many years think the procooler is worthless from what they have told me has been their experience installing them for their 911 a/c clients; however I slightly disagree because it does slightly provide a very small amount of 911 A/C system further cooling. But a procooler is sure not going to make your 911 cold other than only a couple of degrees at most. It bothers me that people waste their money on a procooler trying to find a 911 A/C solution. They would be better off to buy a cheap rear PF condenser that they could make fit inside their rear deck lid.

FYI Cab the owner of Rennaire tried to buy one of my early design rear deck lid patent pending PFC’s after I sent him a front and rear matched set of one of my versions prototypes and wanted an exclusive to this particular design I made for him after we exchanged design Non-Discloser agreements, but I turned him down to give him an exclusive. Cab did send me on of their front evaporators and still owes me a pro-cooler. Their evaporator they sent me was ok in testing I guess for serpentine technology; but I found it and the other manufactures serpentine evaporators I have thoroughly tested and evaluated to not be much better than a stoke OEM Behr Porsche tube and fin technology evaporator.

This is why I designed and fully tested my new state of the art 911 PFE PHASE II evaporator that I have just been too busy to put on the market, because I have had a much more important Invention I call my 911 A/C SYSTEM discovery and new invention that went right over the heads of ALL the stupid pelican posters that fill every a/c thread here at pelican technical discussion a/c area’s

My new state of the art early 911 A/C System Invention will never be made available for DIY’ers. I have given an INSTALL exclusive too Stokes Automotive Porches ONLY For Florida 911 owners and AT ONLY IN Stokes Porsche shop in Ft. Lauderdale installed in Justin’s Shop.

I am extremely different than any of my main aftermarket 911 competitors they all use old technology I consider obsolete heat exchanger technologies and I only use state of the art heat exchanger technologies of today and the future as soon as they change to something new or better is developed.

Griffiths for the serpentine heat exchanger technology they offer I strongly believe is obsolete, although I must say to be fair Griffiths has only high quality components for everything they offer along with excellent product support.

However I also believe using wheel well heat exchangers is stupid and totally not needed to get extremely cold vent temps with R123A unless you are stuck with using an old serpentine technology mentality; because I know that that it is a fact with serpentine technology heat exchangers including the latest serpentine technology designs, serpentine must have more surface area then the early model 911 body has available because they have a low level of heat exchanger efficiency, and due to the well-known Porsche A/C heat exchanger not having enough room for early technology heat exchanger surface area available in the first place with early heat exchanger condensers so Griffiths was forced to add extra heat exchanger condensers surface area running 3 or more in total condensers to get enough liquid refrigerant from the high temp/pressure compressed refrigerants gases so the evaporator would provide comfortable temps in warm ambient temps without starvation.


FACTS!
State of the Art Micro-Channel PFC’s A/C technology has the unique beauty serpentine technology completely lacks and can never have;
Micro-Channel PFC’s technology not only has newer technology that allows approx. 30 to greater than 45 percent more efficient than any serpentine technology; Micro-Channel PFC’s technology HEAT EXCHANGERS SURFACE AREA CAN BE approx. Additionally 25-35 plus LESS/SMALLER IN SIZE FOR SERFACE AREA (THAN ANY HEAT EXCHANGER TECHNOLOGY CREATED BEFORE IT) AND STILL HAS THE SCIENTIFICALLY PROVEN CAPABILITY TO STILL BE approx. 30 to greater than 45 percent more efficient than any serpentine technology!

THIS scientific A/C technological fact related to limitations of the Porsche early model 911 body cavities design flaw related to limited/TO SMALL A/C condenser surface area when using only 2 of my custom designed State of the Art Micro-Channel PFC’s A/C technology made specifically for early model 911’s 30 degree vent temps in very high ambient temps of at least 100 ambient temps

No one cares Reid. Lol most of us myself included don't own anything from Retroaire. The point I was making in posting their graph is not that it is good. It was that the tech is in fact different and not the same among various types. An assertion that wwest was making to an unsuspecting poster.
Carry on with your sales...

Sales??? He is selling hot air so far. Years on and nothing to even beta test except for his friends in his back yard.

Then he posts a chart showing the high temps in the US and guess what? None of his products out West where its warmest...

Agree... no one cares until "sailor boy" comes up with product for sale. And the 1st of July in the middle of the hottest summer in years is a tad bit late...

And how many sales or even beta units do you have West of Florida? You know, the HOT part of the country.

It was 92 this morning when I woke up and your HIGH of 90 in Florida is not even that hot!

Get real!

[KelogGes]

Joe I was more than WISE deciding not doing anything for or with you and dumped you last year,

get over it

you need a life besides living in the Pelican threads constantly making stupid comments over nothing but your self indulged insanities, quit acting like a fool and grow up and be an adult and get a real life outside the Internet.

Your no better than your buddy wwest and the all the other fools who fill all the A/C threads with nothing but multiple pages of useless drivel!

Ahh Sailor boy,

I am really glad that I kept all the emails and get an email transcript of the voice messages YOU left on my cell phone. Would you like me to post copies of them here?

The ones from you begging me to return your call "Joe, please call me back when you can, I finally have some condensors that you can try on your car. Please, I need a beta tester in Arizona and want to work with you!" On and on, over and over and yet you never came up with any product, so I went with Kuehl, something available RIGHT NOW that works.

WWest a buddy? Sorry pal you have me mixed up with someone else. My A/C threads are productive and my car is putting out vent temps 70 degrees lower than OAT (118 degrees outside air temp and vent temps of 48 degrees TODAY here in Arizona!) but you can keep slobbering and drooling all you wish!

LOL.

Only does wwest assert that if you don't call someone out on a technical error, then you accept the technical error as actual truth. The very fact that he asserts this is mind-boggling.

Cavitation doesn't happen in the gas phase. Ever. Even at turbomolecular pump speeds (over 100k RPM.)

[Joeaksa]

Reid,

Lets end this little game.

Its very easy. You came on the PP board saying "I make Parallel Flow Micro-Channel Condensers for 911's front and rear." This was TWO YEARS ago, plus or minus a couple of days. We did not ask you to do this, you did it on your own.

Its time to put up or shut up. Produce the condensers you keep posting about FOR SALE and open to anyone and everyone to buy them and install on their cars or stop dangling this carrot in front of everyone (especially the newby's who do not know of the games played in the past) and continuing this train-wreck.

You have lost creditability with 99% of the people here with these games. Win it back... show that we are all wrong and start putting out these new condensers.... or STFU and go sailing.

Joe A
