Topic: air conditioning on Flathead


stanwalker    -- 04-06-2017 @ 5:32 PM
  I have an 8BA flathead in my 53 Meteor. It was bored 40thou. when rebuilt has edelbrock aluminum heads and edelbrock sure flow intake with twin Stromberg 97 carbs.
All converted to 12 volt including an electric fan.

Am considering installing a Vintage Air a/c unit and need to have input from others who may have done so. Items of interest to me is any significant effect on temperature, loss of power, etc.

Thanks in advance,
Stan Walker s.walker4@sympatico.ca

  I have been considering this kit for my '37. Maybe it could work for you.

  Very interesting. I especially like the idea of not using the engine to power the compressor. That would save on engine horse power loss and have less effect on possible overheating problems. Especially on a flathead. I would assume an Alternator would be preferred over a 12 volt generator.

  Just giving this post a bump back to the top and wondered what others opinions would be.

If you use the alternator to supply current to run an electric motor that will in turn run a compressor you will use more energy and create more heating problems than if you just ran the compressor direct on the motor.

  I have seen several l952-l953 cars with AC from the southern states. They have told me they have no problems with them.

  So your saying it takes more engine power to turn an alternator than it does to turn an ac compressor?

  I think he is just saying that, under the basic laws of physics, the energy needed to drive the compressor will still be coming from the engine, so the engine will still have a loss of power. The alternator load on the engine would be way more than a typical alternator load.
