That is not a Turbo!

Here is an update and likely not completely correct of a schematic of my 1989 Carrera AC system. Looks like two nice locations for micro channel heat exchangers.

Please comment for mistakes or other items you want shown. I added better detail on how the receiver/dryer works and now show the high and low taps at the compressor as others mentioned.

Thanks Guys for correcting me!!!', YOU ARE RIGHT its not a Turbo I made a mistake; we had 2 1998 911s in the shop today a brown one that was a turbo and this black one that is not a turbo ;

Regardless I have shown this black 98 911 because of its deck lid condenser design and its hose fittings to show its early 1989 Porsche 911 A/C technology ONLY

Somebody's HOT SUMMER in Texas is going to have an ICE COLD 911

There is a a new revision to the deck lid rear contour condenser the right high pressure connection fitting was changed to a different place and angel and also on the contour condenser the 0-Ring fittings are #8 in from the high side of the compressor & #6 out to the front condenser

The front condenser by request is #6 in from the rear deck lid contour condenser & #6 out to the filter dryer in the left front tire wheel well

Very nice looking!

Anything you might have that would fit in a LH front fender? I do not have room on the back lid for a condensor there so have to put one elsewhere.

Thx,

Joe

Howdy Joe,

ANYTHING I HAVE NOW NO; not at this time

this pair you see are currently handmade highly customized for 63-98 911s pushing the envelope of limits of available room both front and rear with the latest parallel flow micro channel technology that is 30 to 45 percent more efficenct then ANY PRIOR technology and have been sometime in development, they are not even into production yet, but by special order

But I may make fender units later after what I am doing now is in production; and depending on demand???

Have you checked out what Griffins offers for fender wells ? They are using older serpentine technology but they have good products

I noticed you are also into Jags, this might be a potential market also for later, I am also considering big rig trucks for on top of the tractor-cab condensers that are forced to use after market tube & fin or serpentine technology and there are millions on the roads

I am interested for my 1975. However, I don't think I have a front condenser. It should still work better than stock? Right?

My car now has only the single rear condenser (the Retroaire one....not as nice as this part, neither as big) and so far I have zero cooling problems. Outlet air is in the 36 degree range on a 29 degree (c) day.....

I suspect this one will give more than enough cooling capacity all by itself with just the engine cover condenser.

Cloggie,

I used to live just East of where you are and the climate is no where near what we have in the Southern part of America. We used the A/C on our 1981 911SC only about a month out of the year.

As long as your temps are in the normal range, a improved condensor like these here should be a big help. Have you also upgraded your compressor? Forgotten what year 911 you have but if you have an older style compressor that might also be something to look at.

KeloGes,
Great product. I am working on a highly modified turbo. I do not have room in the tail for a condenser. I think Griffiths has one that fits in the back of the rear fender. Any thoughts on this configuration? Maybe 1 in each rear fender - I am not a engineer on this subject, just asking stupid questions.

Also, I still can use the stock location up front.

Thanks for the info. Excellent thread.

Mark

My front location has a big oil cooler. My left front fender is available though.

Agreed and no debate, the larger condenser will make a difference as the outside air temperatures get higher.

In my case, all the parts are new as part of the Retroaire kit, compressor is a Sanden (507 if I recall) and all the parts seem well matched.

I do like what this guy is doing, I hope some of the distributors pick up his parts or perhaps he gets into the business of selling full kits/upgrades. I wish him well.

Thank you for the comments Cloggie,

I will be Very soon offering complete kits for these 911 models i have stated <grin> i.e. reduced barrier hoses, dual front and rear PFC condensers, filter dryer, evaporator, thermal expansion valves (TXV) & (VOV) Variable Orifice Valves, insulation & sound proofing materials , maybe even a pro-cooler; The Whole Ensalada of Porsche A/C related parts & accessories etc.

I am doing things in the background I have not said anything about yet

ON another note:
I am also thinking of expanding my PFC product line into other Porsche models ; may add BMW, Jaguar, etc, Big RIG Trucks; and custom made Smaller Universal size PFCs not offered by anyone and also for the automotive, other vehicles’ truck, marine & recreational markets, no to forget medical and industrial markets

Starting by complete accident and making my very HOT old 911 A/C COLD that no one I am aware is doing with the latest technoligies I am using for the early Porsche 911s for aftermarket, now leads to step by step what I am doing now; The potential for A/C and Heat Exchanger cutting edge technology niche markets worldwide is vast so let’s see where it goes?

Howdy Mark,

Thank you for the kind comments!

hmm I will think about it more related to a PFC that will fit in other placesl

IT actually would be FAIRLY easy now for me to make almost any demensions I want, but I do not reallly know what the demand is for these type of units in other places in the body ?

What an awesome thread! Wish I had seen this when I added air to a 69 911T a few years ago. I would have placed an order on the spot for KelogGes' rear condenser.

One thing I'll add for anyone wanting cold air from a 911, and a lesson I learned from building mine, is that a significant amount of air will bypass the rear condenser when the decklid is closed, as it just enters the engine compartment through the gaps between the decklid and the body. You can seal these gaps with generic automotive weatherstripping, available from just about any autoparts store.

Mark, no room in the RH rear fender, your oil tank is there. Thats why everyone is using the left hand side front and rear fenders.

Frankly I try to stay away from the LH rear fender as the last thing the 911 needs is MORE weight in the rear, so the front is a ideal choice. The hoses have to go in that direction anyway so might as well. I work with aircraft for a living so running hoses is not anything new to me.

Just wish that we had a new generation condensor that would fit in the front fender to work with the nose condensor!

Joe A

Joe,

what are the approximate length and width demenions that would work for the condenser area you are talking about if you know?

Reid,

Thanks for the reply and let me get a tape out and do some measurements. Am very adaptable on size, just need enough room to make a shroud (friend has a vacuum machine that can do this) for a fan then stick the puppy in one of the fender-wells and plumb it up.

Odd Job and I are looking at buying two of the front under-bumper condensors from you and I would rather get something that would work in the "fender" area as well from you. Believe that he is going to get a deck-lid mounted condensor from you as well, so we are looking at 3-4 units. If we got them all from you they would be matched in their flow rate, so the system should work better.

Any suggestions on a more modern Evap unit? Griffiths is more money than this poor boy can afford, and the guys in Dallas (Rennair) refuse to sell them without buying their kit, so they just lost us there.

Thx,

Joe

KelogGes,

Since you are entertaining condenser setup other than the rear decklid or flat front location, I would be interested in the possibility of a front condenser which would be located upright in the front center oil cooler location. I think to get enough condenser to only run a front condenser and no rear decklid unit you might need to double the thickness. This could have a pull thru fan to ensure air flow at stop or low speed.

This would look like a front oil cooler only rather that a single core it would have two cores stacked front and rear.

I am including photos of a oil cooler install to give you an idea of the proposed configuration. The dimensions of the oil cooler are 5.5" x 2.25" x 24"

This is not a rush project as it sound like you have some immediate interest in the parts you are developing.

great Idea to get a tape <grin> i am Curious to know what the demenions are

FYI I can get you a Rennair evap with out you buying their Kit, read my next post about RennAir

if you guys go together at the same time i am sure we can work something out if you like for you and your friends.
