It would appear that Barney is ready to instruct the WHOLE world that technology NOT used since the early 1970's is superior to Everything produced since that time - (Yawn)... There is a very good reason that technology is over 40 years old... It is NOT as efficient as more modern AC compressors! We all know about your 45 year history working on cars and no matter how many times you repeat that, it doesn't seem to make you any more intelligent, now does it?
You want to know just who the WE was in 69ShelbyGT350H's post?
If you would have bothered to read some of the links he posted to the OP you just may have noticed his information came verbatim from Vintage Air and their interesting and ACCURATE page of information and descriptions on all types of modern and vintage AC Compressors... You may, and probably will disagree, but I'm pretty certain that Vintage Air has a LOT more Experience and Knowledge collectively than you ever will have on this subject, and their experience and knowledge is largely based on our vintage cars. Hey, NOBODY knows everything and even YOU still have a chance to learn new stuff! (perhaps like Diesel Trucks... LOL)
Please stop trying to berate EVERY person on these forums who happens to have a different opinion than you, many of them come on here with experience and knowledge of their own and are just trying to help others... Please try to remember. Even with your "45" years of "Experience", your viewpoint is just YOUR Opinion, just like everyone else who tries to help others.
And yes, your replies are often very informative and have helped many on these forums and is greatly appreciated, but when you go off on people you make this forum a less enjoyable experience than it is supposed to be... I have to take meds for my anxiety, perhaps you would feel better if you did too!!! :)
Moderators, please take note...
