BULL****!

LOL, nice.

You say "expensive" - define "expensive" in U.S. dollars, please.

This is Justin Stokes custom install work in progress of my latest version Rear PFC into the rear RSA retrofit fiberglass decklid

Note: Its not finished yet and needs to be sealed better etc;

Joe look carfully at this photo of TRA Motors Decklid for this RSA especially the outer corners inside the engine compartment of the air-intake and notice the AIR INTAKE CORNERS Fastener NUTS


RS RETRO BODY PARTS made by TRE Motorsports Inc, Van Nuys, Ca; TRE Motorsports

IS THIS THE SAME AS YOURS OR IS YOURS DIFFERENT???

"These 4 outer corner thru-bolt "NUTS" fasen the NON-OEM (& not perfect copy) black plastic air TO THE DECK LID" and create a bit of a problem not allowing my rear countour PFC not to fit perfect to the sheetmetal and make it easy to only add some rubber molding to have my PFC perfectly seal air tight; like it is desinged to do on an OEM decklid that uses a whale tail

NOTE: in comparing tre motorsports ("not perfect OEM air intake dimensions") rear RSA retro-fit duck tail deck lid in order to properly perfectly seal the PFC creates a challange to perfectly seal the PFC to the deck lid; and requires extra time; special custom made faseners; and/or several other options that can be engineered and/or some slight decklid inner modiffication

I do not know yet if your decklid body parts are the same or different yet than this one? regardless we will have to talk about ENGINEERING PFC FIT of the components voice to make it easier for both of us; I dont have tons of hours typing engineering we can probably do in a few minutes talking; there are several ways to tackle an engineering installation all of which would bring acceptable results.

I firmly believe from my personal testing for many months last summer DAY AFTER DAY including through the highest South Florida record high ambiant temps records that were broken during my tests, to get highest efficencely from my rear PFC it needs to be completly sealed to the deck lid air intake to allow as much outside air (all the outside air entering the engine compartment) as MUCH AS POSSIBLE TO BE FORCED THROUGH >> the PFC micro-channel fins enhancing the heat exchange REFRIGERANT CONDENSATION to make the A/C sytem potential "AS COLD AS POSSIBLE NEAREST & ALMOST TO EVAP ICING WITHOUT ICING" !!!

Justin @ Stokes Automotive, and I as a marine engineer; have a different viewpoint at least at this juncture related to what is fine "FOR VERY COLD temps" he is happy with air vent temps @ 41F or so degrees, for me its 31-33F AND NOT ICING!

JOE FOR you using R-12 and PFC's your going to need a good thermostat for highly controlled ICING on your windows but as a pilot you know how to control icing (smile)

Thank You Alfonso I will PM you soon. HOWEVER I CAN'T PM YOU because you only public acess and have not registered here for a PM account.

FYI I have been able to deliver PFC's for several months now in a couple of different PFC versions, with more to follow;

Please understand that each PFC is currently individually custom handmade and designed and prepared for each particular 911 owner due to several variables of hose connection issues.

But have intentionally put several people on hold that wanted delivery, because I wanted first to publish a couple of complete test installs with pictures, and the proposed testing 911 owners have had scheduling issues that delayed them bringing their cars into the Justin’s shop for months to have thelr installs done.

By the way, I have another install test right behind this RSA, I think you will be interested in; that I am going to start posting pictures for a black 89 911 Carrera Cabriolet as soon as Stokes Automotive finishes this RSA install and test, and the owner brings the Cabriolet into the shop after the RSA is finished,

Stay Tuned

This picture above you will see on the upper left side; “ONE” of my "NEW Custom Made A/C INLINE MICRO CYLINDER FILTER's";

This “ONE” shown is installed for filtering the refrigerant flow coming out of the Front PFC OUTLET hose Line fitting then going into JUST BEFORE the A/C System line Dyer in the wheel well & also before going into the Evaporator; PROTECTING THE DRYER, EVAPORATOR & THE COMPRESSOR from damage that is bound to happen in time!

Note: I STRONGLY BELIEVE IN PREVENTITIVE MAINTENANCE,
Having a couple of These little puppy's installed in your a/c system can sure save the A/C system owner a BIG heart ache and a ton of money in the future to say the least!!!

This particular filter SHOWN protects both the inlet to the dryer and also even more importantly the next inlet to the compressor from any debris in the a/c lines.

There will be another one (not installed yet on this car yet) that protects from any debris THAT Will Come From The Compressor THAT IS BOUND TO HAPPEN IN TIME, from entering the PFC's and blocking the condenser Micro Channel Miniature Tube Holes CAUSINGLOS OF EFFICENCY:

Nice looking work. Wish I had room to do that but do not, my oil cooler is in that spot.

[KelogGes]

ahh ohh

Joe can you move your oil cooler back about 7/8s inch from the rectanglar front screen opening to have both fit butt together and share the inlet air this way? ? ?

Note: I have not personally examined the dimenstional variables of the depth behind the RS's body kit screen and the front sheet metal very good yet

If you notice from my pictures I or should I say Justin dont have fans attached yet on the front condenser

[KelogGes]

I am not going to post much on pressures & temps yet (LoL) but I will say a couple of things

I will let Justin Stokes of Stokes Automotive do this here under his own login, in a his own full report when he is ready too very soon, and you can believe it or don’t, from a 25 year respected Porsche Expert because this is his totally independent of me install not mine.

Anyway it was my observation of Justin’s Statements to me during this only preliminary test even without the “rear PFC not being fully sealed yet on this RSA” and “no fans mounted on the front PFC and the full front retrofit cowl completely removed” and the car on the lift near ground level @ 81.8 degrees F ambient inside the shop, “With only 1.5 lbs R134A”; .

Justin said from his long time experience to me; initial pressures were “within his concept of "perfect range for very cold 911"

With an outside the car shop fan several inches from the front condenser and not sealed; and the rear contour PFC ONLY partially sealed to the deck lid

Low side pressure was 9 lbs; High side pressure was 220 lbs @ about 2000-2200 rpm; Lowest air vent temps were 42.8 F with a 12 second run time on the compressor at which time the computer controlled thermostat shuts off the compressor; which I think are rather short compressor on time @81.8 ambiant; With only an outside the car shop fan several inches from the front condenser generally aimed at @ the car front PFC and not sealed to the fan at all;

Note: At extended idle times of several minutes inside the shop air vent temps was 43.3 F with the shop fan blowing toward the front condenser several inches away and not sealed

But FYI Justin Stokes after being such skeptic of what I have been DOING IN HIS SHOP and also telling him and showing him my prototype work this last year and even before;

"That until he personally installs my PFC's HIMSELF on a 911 he don’t believe anything I say about A/C on Porsches". (This is important TO ME because I have tried to argue with him about what I am doing to no avail for a very long time and its been useless to argue with him to the point where he almost perminentlyh threw me out of the shop about this several times).

However Justin "FINALY CHANGED HIS MIND ABOUT MY PFC's" he told me YESTERDAY
He told me yesterday for the VERY first time, HE IS “FINALLY A BELIEVER of my PFC's and what I am doing”; he also offered to buy me a special welder to help me do more condensers ROFL

(NOTE: The factory 1994 RSA A/C thermostat will only allow the air vent temps go down to ONLY about 43 F on this car DUH;;;; and a way will have to be found that should be easy to either alter this A/C's lowest thermostat computer setting or to bypass it with a different type digital or analog thermostat) I know From my own personal testing last summer on my old 911, I know exceeding lower air vent temps with my PFC's with R134A 911 well below 31 F is more then do-able with a bit of tweaking; believe it or dont!

Let me give it a check and get back to you... its tight there. I have the RS front bumper/cooler ducting right in the middle.

Wed 3-28-12

Justin removed one of the computer controlled thermostat system probes that goes into the evaporator and the RSA air A/C vent temps dropped "Down to A SOLID EXACT & Continuous 36.0 F" when he drove the car for the first time & still with the front after market body kit removed as you see it here.

Although Justin took many pictures today when he took the first preliminary test drive of the car with the front body parts still removed, unfortunately this was the only picture that is readable and shows air vent temps @ 36.3 F.


Note: Although one of the computer controlled A/C thermostats that goes into the evaporator was pulled out and air vent temps "Went Down to 36.0 F" in a test drive with ambient temp of 81 F, Justin told me that the compressor clutch was still cycling off and on @ 36.0; he believes another computer controlled thermostat probe someplace else besides the one going into the evaporator he removed was still causing the compressor to cycle on and off preventing it so it can make colder.

Joe Thank You for showing me the picture of your RS it looks GREAT, the body kit looks very similar to this one.

FYI I am going to have to somehow find small water resistant special fans for this 2004 RSA that will be needed when the car is in stop and go traffic, that will fit between the front PFC and the front OEM sheetmetal small space and they will be difficult but not impossible to find. LoL

The owner of the RSA would like it back asap but he is also reasonable, so I think I will let Justin finish and wrap up what he is doing very soon and let him take it home and bring it back, while I find and engineer him some small front fans and also clutch thermostat and better/different thermol expansion valve etc to make this car even colder lets say 31F or colder. He can't complain about a/c cold anymore its now getting down to 36 with the front body kit off and no front fans.

FYI I have an 89 911 Cab up next waiting in the wings to bring it in to Justins shop that wants cold A/C and I think you will be also interested in the project.

36.0 DEGREES F. ACHIEVED WITHOUT ANY FRONT PFC FANS; ONLY DRIVEN ONCE FOR 2 MILES ON VERY SHORT SIDE STREETS IN STOP & GO INCLUDING TRAFFIC THEN BACK TO THE SHOP







JUSTIN re-installing final body parts



RSA READY for the Owner pickup

NOTES: The RSA A/C system at this point has not been tested on the highway at normal driving speeds by Justin, only on short side streets for quick tests only 2 times, but so far has achieved vent temps down to 36.0 degrees F without any front PFC fans.

The car has been at the shop now for several weeks and should have been completed about two weeks ago, but due to Justins busy high work load for his other Porsche customers his testing time was very limited and ran out of time & the owner needs his car back for now.

So I will call this "RSA A/C Phase 0ne 36.0 degrees F"

In a three way conversation today between Justin, the Owner, and myself: the owner has been fully informed that the car A/C modification & testing has gone very well so far and is not yet fully completed yet, but we both want him to go drive it and enjoy his now cold A/C and report back to US his temps in varying driving conditions; and he agreed to return after I engineer special front PFC fans for him

We know from Justins short tests so far the car is getting pretty cold when driven a short distance without front fans it will for sure need for stop and go traffic, when it is brought back to install the new fans we will also do a little custom tweaking & a few tricks we know to make it even colder we have not had the time to do yet.

FYI: BASICALLY THE ONLY PARTS MODIFICATIONS TO THE RSA A/C System that were performed BY JUSTIN THAT WERE NEEDED from stock where replacement of the original Factory OEM Behr evaporator that was damaged & had internal leaking with another new stock Behr OEM replacement; the original Porsche stock factory compressor was used but had a slight modification adding Schroeder service valves, it did not have for servicing the refrigerant gases; removal of the cars condenser (Addition of MY custom made PFCs for this car) one front PFC and one rear Contour PFC; the old a/c hoses were also retained but were modified on the ends adding new hose extensions and new O-Ring fittings in a couple of places as needed.
