I understood it to be a problem with sustained high RPM operation, like with a lower geared car. A different pulley would hurt low RPM A/C efficiency. Sustained high RPM operation a problem, true or not, I don't know.




A 440-4 would have come with 3.54 gears standard. A/C was available with 3.55s.

Was there something different about the pulleys or compressors used on a 3:55 gear car with A/C that couldn't be used with a car that had 3:54?

Is a compressor running on a 4,000 RPM car with 3:23s seeing something different than a car running 4,000 RPM with 3:54's?
