I actually am thinking maybe it isn't the horsepower it takes, rather it's the resistance to change speed.
I know that feeling. I never would set it to max, always to Vent or something so I could hit the A/C button if I needed it to actually go. It doesn't help there is no WOT A/C Disable. If a '88 Mustang has WOT A/C cutout, why doesn't a '98 Chevrolet? I tried to figure out a method to install a WOT cutout on the Cavi before I got the Vic. The only way would be to tap the TPS signal and setup another circuit to pull a normally closed relay open. Unfortunate, as it would have been nice.
Its the lack of torque, I think. Like you said your Expy or Mustang dont really notice.. More cylinders to spread the load.
I read somewhere that Car A/Cs were REALLY oversized for the cabin space, due to people wanting to cool it as quick as possible. I think it was 1-1.5ton?
