According to the AC data sheet

Quote

The Electrocooler electric air conditioning system for Porsche 911 is a revolutionary update for the complicated A/C and ventilation setup fitted to Porsche 911 models from 1974 to 1989.  

Would it fit into a 1970 911 model? The car is LHD. I have seen cars that are 1974 - 1989 and the places where the AC parts are supposed to go look more or less the same to me.

Thanks,

The kit has been fitted to F-body cars, the main stumbling block is the battery boxes which take up space under the front fender.  Many owners choose to delete the left side battery and do away with the box (this is not an uncommon thing to do anyway).   Alternatively, the condenser(s) can go at the back of the car in front of the rear wheel.

We recommend using an installer who knows their way around Porsche 911s.  You can check our installer map to find one near you (link below)

Thanks for the pointers. We saw that the AC manual had actually covered the F-body peculiarities 🙂

Today I ordered the kit with the 2 condensers. The engine will be getting a rebuild and while we're at it we'll do the AC installation.

Is it correct that the ECU need not know how many condensers are present in the system? And that when steady state is reached (assuming the system is not out of thermal capacity), the temperature in cabin should be the same with 1 and 2 condensers?

The dual condenser systems can produce lower vent temps but yes when thermal capacity is not exhausted the temps will be the same.

There is no need to specify the system size in the ECU. Thanks for your business!

I have it installed in a 1970 911S with LHD and the work was done by a local shop that has done about 8-10 systems. Happy to answer any questions regarding F body cars.

Hi. How is the air flow distributed inside the cabin in an F body car (there are no vents). thanks

The F body has fewer and smaller openings than the G body. The main vents are two round holes above the L and R footwells. They seem ideal for letting heated air in in cold weather. Then two narrow slits, on both ends of the dash, and one long slit underneath the windshield. My 911 is currently getting its engine rebuilt and soon the AC work should start too. I hope the new blower and the second condenser will compensate for the smaller vent capacity. I'll write about the results when everything is completed. Hopefully before the onset of winter.

In July I had thermal foil installed, with a light blue tinge, super discreet and it gave the car a sweeter retro appearance. We drove around for a day in 30+ and it felt like the cabin was getting much less heated in direct sunlight. Much more bearable than our last long road trip in June. This was an inexpensive upgrade and I highly recommend it.

Thanks! Where did the condenser go? I purchased the AC with two condensers. On Monday I had a chat with the chief mechanic and his plan is to mount them both in the rear fender. He didn't like the option to delete one of the batteries to free up space for the condenser, for three reasons. It will mess up the body. It will affect the front/ back/ L / R weight distribution. The battery capacity will drop.

It is always best to mount the condensers away from any heat source  

If it is very hot where you are, mounting both condensers in one rear fender can be an issue due to heat build up.  911s get very hot under the rear fender, especially in traffic.   This can cause the compressor to shut down.  
 

Deleting one battery is not an issue since you should be running our alternator which will cover the amp draw.  The Odyssey 925 is a good small battery that will fit in one battery box. I have run one myself for the last 7 years.
