Singer AC

Singer with a rotary compressor in black; still hard to beat at it's intended job. A 1600 watt "hair dryer" is ok for defrost like the rally cars utilized. Not so much for "real" heat in the real world.

We removed the factory front and rear condensers, the compressor and all the hoses. The electric compressor was mounted near the battery (where we normally mount it on RHD vehicles). We used our condenser assembly up front, new drier and hoses.
You just described my situation, maybe without the factory fresh bit. I am close to making a purchase, would like to know more before I buy a ‘traditonal’ compressor etc

The compressor has nothing to do with heat?

A 1600 watt ‘hair dryer’ left running for 30 minutes in a tiny 911 cabin would warm things up considerably. Tie the warmth with the Ac and you’d have very effective defrost, which is a major issue in 911s.

A truly cosy cabin would be the electric heater and electric heated seats, assuming the new fancy alternator is up to the job of running both plus the Ac.

Also a provision for plugging in the system to a standard household electrical outlet to operate for pre-warming (or perhaps even cooling) the interior in cold climates prior to getting in the car and driving away would be immensely valuable. Then the heat/defrost would only have to maintain the temperature running off the alternator afterward.

^ That’s a ‘mainline’ Singer with a standard compressor. The DLS is altogether different with a custom fan housing, shroud and intake. There is nowhere to mount a compressor on the engine.

The rally cars only had 300W for demist and I agree that this is not enough power for cabin heat. Neither are the masses of eBay electric heaters on offer.

Most Eberspacher/Webasto gas heaters are 2000W so 1600W is not a huge downgrade for a small cabin.

Porsche 911s are sports cars. For most people, that means a run out on a cold morning, not so much Arctic expeditions. If you need heating for sub freezing conditions, keep the heat exchangers.

I don’t think you understand how heaters work

My kit arrived last week! I'll be sharing the installation as well as review for Florida/Georgia humid weather from there. Targeting to be done before a road trip in May.

Progress thread here
