new carb installation

You didn't read my post either. I said I would try it without it first. I didn't say to do away with it. If it bogs down with the air on then reconnect it. If not then don't use it. It looks like the way it's designed he can keep the vacuum connected to it and it will still shut off the compressor when going up a hill without having it connected to the carburetor. I imagine it was connected to the carburetor to boost the idle with the A/C on. Similar to what today's cars do by computer. That's probably why it's referred to as a "fast idle device".

That is a good point about trying it first and see the response. I will keep the device around incase i need to put it back on the car once I get the AC going again.
Thanks for the information Sir.

I would definitely keep it. Even if you don't use it I'm sure there's someone out there that's looking for one for a concours correct car. I imagine they are pretty rare since they were only used for about a year and a half. Probably a lot of them were taken off and thrown away. I've had lots of Thunderbirds with A/C and I've never even seen one.

...You say "today", is this something you have come up with?

I'm not that smart. WOT switches are mounted on just about every Electronic Fuel Injected throttle body out there. They indicate, your pedal is on the floor, you need as much HP as possible right now and 'get me off the tracks!'

Back in the early '60s, 'conservation' was never high on the list. If you added a device that used HP, you simply got a bigger engine. Pretty soon, family cars had engines that hovered around 390-400 cubic inches. I NEVER thought I'd see a Cadillac with a six cylinder engine but my uncle has one.

Engineers started to re-evaluate power needed for each 'thing' to do its job. For instance, your mechanical fan. Mechanical engineers HATE the electrical guys. For this reason, de-clutching fans were introduced. After further investigation, nobody could substantiate the need to run a fan at all when the engine is cold. Electric fans only turn on when the radiator is hot. Sometimes months pass before my daily driver's fan turns on during Detroit winters. I still see trucks with a radiator cover all zipped-up because he can't stop his fan.

Just about all functions are controlled by electricity now, including the transmission shifting. The result is HUGE efficiency gains with much better allocation of power from a small engine. Grand Marquis and Crown Vic, before they were dropped, had a Romeo engine that was shy of 300 cubes. Yep, Police Interceptors, too. Back in the day they were 427s. - Dave
