What determines the duty cycle of the A/C compressor?

Again, you should quote who you are posting about, who is giving out wrong information? Illusionx is or was the the only one on here that thinks that the compressor is engaged 100 percent of the time. There have been several post to explain the opposite since that post.

True, quotes are helpful, but mine wasn't directed at anyone, other than simply stating some facts relevant to the thread.

I will quote more in the future.

I put in a AEM cold-air intake and my car no longer bogs down with the A/C on...apparently the engine is starved of air under stress...its really easy putting it in....well worth the $150... i also use fuel system cleaners in it on a regular basis and use 91 octane gas..its really quick now

22 hp is a ridiculous amount of power for a car a/c. 22 hp = about 16kw. Your home A/C might pull 2-3kw. hp and kw = power the same exact thing but different units.

I have owned V8 trucks, and other small 4 cyl. cars with Ac.
And I can tell you my Yaris has been by far the most sufficient with AC on, the gas mileage changes very little, if at all, yes it does bog the engine down a little,
but for a 1.5 I would say it is pretty good, and really not a whole lot.

33,000 miles on 2008 sedan, and no problems.

That's what I wanted to say!

The AC compressor stays engaged, until the AC is turned off....

This thread is going to be another one of those threads where people just spout out information that they've heard.

I've dyno'd the car, with and without the AC on. 3 whp difference.

Hahahahah that cracked me the hell up. Guess when my head lights are on doesn't mean my car engine is still running huh?
