FORUM RULES: Users agree to these Rules when using Forum.

The site administrator reserves the right to change the terms and conditions of the user agreement without prior notice to the user. It is the responsibility of the user to regularly review the terms of this agreement.

The user agrees to the following terms:

All information that you provide to us for your membership is correct.
You will not use your membership to spam, harrass, or exploit other members in any way.
Vulgar, Abusive, Racist and Sexist Language will not be tolerated.
Commercial-type sales postings will not be allowed.
No mass posting or flooding of the boards is allowed.
No Advertising of parts or cars; no Ebay or business/commercial ads (please use the "Classified" for ads Wanted or For Sale).
VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)

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.
