Still waiting for someone to post data other than vent temps..... personally I would like to see what are the temps at the entrance and exit of both condensers, at least, for both forward and reverse flow situations. First is to benchmark the std arrangement, in order to get an idea of how much heat is getting removed from the rear cond and possibly added to the engine, very roughly, not going thru the Qdot calculations .
Then with the reverse flow setup someone could provide those temp numbers.
In this case, the rear cond. should be cooler by the amount of heat removed by the front cond.
So how much cooler air is the engine getting? 5 degrees or 40 degrees change ????
Will it make a difference in oil temps?
We have heard all the talk and theories, the data will show.
Well I was not going to get involved but ,...show the data.

roflmao

LOL Ronnie....

I believe You would need for a proper valid test of comparative analysis at least 4 simultaneous temperature readings on the condensers at the same time , including simultaneous high side and low side gas pressures, simultaneous engine rpm, and resulting simultaneous air vent temperatures, simultaneous evaporator temperature @ the same exact time for the static test, followed by the same monitoring setup on an extended driving test.

Not to mention an integrated DATA LOGGER

Good Luck getting this from a DIY'er

DIY'ers are not laboratory testing facilities, so you're asking A LOT

George Why go through all that ;; simply hook up some temporary hoses after "you already know your current a/c vent temps with out this installed at a certain @ ambient temperature" After temporarily hooking up reverse the gases test it @ the same ambient temperature and take your vent temp temperature "with A THERMOMETER" "THAT WILL ACTUALLY MEASURE AIR TEMPERATURE"
ANALOG OR DIGITAL, I like digital meat/cooking thermometers the best because they are very fast readings of changing temperatures, and you can find them in most grocery stores

NOT an IR or Laser pointing IR gun!! An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called blackbody radiation emitted by the object being measured. IT CAN NOT SENSE OR MEASURE AIR TEMPERATURE!

An infrared thermometer is a thermometer which "infers temperature from a portion of the thermal radiation sometimes called blackbody radiation emitted by the object being measured" BUT NOT FROM AIR! You can use an IR gun for surface's temperatures, but again NOT ACTUAL AIR TEMPERATURE,

A/C STANDS FOR "AIR CONDITIONER" NOT SURFACE TEMPERATURE!

BUT if you must go ahead and do it the hard way <grin>

the in out condenserS temps and the way you are wording what you are requesting will give you a skewed test result

I am trying to help you the easiest way

I forgot to say you can use an IR gun on the fittings on the condenser or the condenser itself because it is NOT AIR, it is surface temperature

Well, I use to have an Omega 32 channel data aq, that would be an interesting characterization.
You do it , right up your alley.

You do it , right up your alley
 

Do your own independent testing, this is better !
But I will come by to view your test if you like


I am completely bias because not only invented this I have installed Reversing The Gases Three times fully tested it and absolutely know it works, and have no interested in testing this again, it WORKS GREAT!

My interest is in state of the art PFC technology new designs and development that are even more efficient and/or PRECISE digital micro processor temperature control of of evaporators @ 32-33 degrees F


Or you CAN wait until the west coast 86 SC Carrera Cabriolet DIY owner posts his numbers and description after he installs the PFC's etc, I am sending him and let him test it for DIY early model 911 community I have given my invention too. The west coast Cabriolet DIY owner is my priority helping him be successful making his 911 ICECOLD

Gas reversal worked great for Bevis, too!

Given that Austin TX in August seems to be the benchmark for testing our A/C performance I tend to think "west coast" is not definitive enough. Seattle, for instance, is "west coast", as is SFO, but IMMHO neither of those would suffice as a comparative test.

Bakersfield, Ca, maybe ???

Reid, since you obviously missed it the first time, it would behoove you to read Eric's words of wisdom on IR thermometers, and then perhaps, you will stop spreading misinformation about them and their usefulness in a/c applications.

Waiting for input from Reverand Sharpton.

This could get nasty.

Yeah, measurement instrumentation is what I do, and have been doing, for decades now. That reminds me, the calibrated micrometer I sent you to use to measure your, ummm, probe? It was in excellent condition to measure very small lengths. I could send you the more sensitive one, of you need to measure smaller. Which, no doubt, you do.

You accidentally sent me the "Eric" model; please ship this one, and I'll report my finding to you, along with photographic evidence, forthwith!

"blackbody radiation"? . . . Maybe Reid was referring to something like this -

Nasty good!!!

I say, God Damn!

Doesn't she need some kind of permit to be packing that much game?

Yes, and yes!!!

bam

I could pull 9 seconds only because of my advancing age.

Willy could pull 15 with the steel rod implant that you have to be 80 to receive, by law.

This type of commentary will get you a blast of "non reversed gasses" at nose level, Bob!!!

?!?!?!

Hey Ronnieeeeeee

You know how Willie says we are married?

How about if he keeps it up we spill the beans about his Mrs at our consummation party and the noise she can crank out when she is being handled properly.

This thread is awesome. Makes me happy I deleted my ac. ;-)

^^^ I think it needs more pics of hot, nasty chics!!!!

Ronnie explain these pictures and the information to wwest and the other children
 

Ronnie explain these pictures OF THE GAS PRESSURES and the REST OF THE very simple to understand information to wwest and the other children in the room

This top picture shows the GAUGES actual reading high side PRESSURE and low side PRESSURE of the REVERSE THE GASES TEST and meter IS SWITCHED ON (LOOK AT THE DIGITAL DISPLAY)

THE LOW SIDE PRESSURE WAS ONLY about MINUS ZERO -3 OR -4 LBS

THE HIGH SIDE PRESSURE WAS ONLY about 126 LBS
And this achieved @ 85 degrees Ambient inside the shop
Engine RPM 2000

Total R134A Refrigerant used was only .95 lbs, which is all my PFC's require to get
32 degree vent temps @ Ambient 92-95 degrees

That was further verified and proven in SEVERAL driving tests at higher ambient temperature tests

THE bottom picture SHOWS Gauges IN CLEAR focus for clarity. so you know what the top gauges show you cant read as well

http://forums.pelicanparts.com/uploa...1428443211.jpg[/QUOTE]

bottom gauge picture is switched off has no electricity and is used for clarity understanding of the top picture the 911 engine is switched off

Ronnie where are your actual driving test pictures showing proof of your extended driving tests for "your claim of 27.x degree vent temps and your evaporator does not freeze up", together that also show ALL your 911 engine monitoring gauges including your speedometer at the same time you show 27.x,


What refrigerant do you claim your A/C is using and how much???

Where are your actual A/C pressure gauge pressures and manifold pictures showing your A/C system running when the engine is at 2000 rpm showing the gauge pressures together with your vent temps?

Prove your BS!


Like I post when making a claim OF LOW TEMPERATURES

Compliments for exploring Reid.

I have announced I have a DIY owner that will be getting my latest version of my PFC’s designed for reversing the gases and wants to finally make his 911 ice-cold that lives 3 thousand miles away, and he will install them and also Install reversing the gases and do his own tests, I will help him every step of the way with technical support everyway I can.

George respectfully tell you what, as you know I have explained to you exactly how to do this; if you want to meet here in south Florida perhaps there are other early model 911 owners and/or PCA members who would be interested in being a part of your reversing the gases test on your 911, or perhaps others here will want to test this themselves or learn more about it? I have released this to the world and do not expect to make a penny on this discovery.

As I said I am biased making this claim after discovering it and successful installing it; it is already being used on several 911s, and is being used by a well-known Porsche Repair shop I proved it to and gave it to too USE; and they do regularly !

I do not want this information hidden I want to give this to the world of early model 911 owners for free, to give something back and pay it forward.

I do not need to test this, I ALREADY HAVE; IT WORKS GREAT,
I HAVE NO NEED FOR A BASELINE USING OLD TECHNOLOGY, HOWEVER IT WILL WORK REGARDLESS OF YOUR SYSTEMS TECHNOLOGY AND MAKE YOUR A/C SYSTEM COLDER THAN IT IS NOW with the heat exchangers you have!

IT’S time you and others test it on your various early model 911’s with OEM Stock, modified or whatever 911 early model A/C systems you have, so I will make myself available to a group of south Florida owners that wish to discuss this and/or test “reversing the gases”!

Thanks Karl
