But if you're not building a monster of a drag car, leave the AC in your car. It would be a larger pain to remove, and more costly for a custom length belt then what you might save.

its not so much about hp gains, but being able to rev the engine faster.

25lbs honestly means nothing on the street.
And honestly if you want your engine to rev quicker then change out the balanceshafts go with a lightweight flywheel and do internal engine work.
On a street driven ls cobalt theres absolutely no need to remove the a/c.
Also current a/c compressors can usually spin a few revolutions just with a simple spin of the hand. They dont have a lot of resistance.
So the facts posted wont matter unless your building a race car. And honestly if thats the case then you have a lot more ahead than just deleting the a/c!

yeah looks like this.
thats what i'm running. fidanza flywheel, zzp stage 4+ with sachs pressure plate, no balance shafts, no a/c, electric water pump. and the ac compressor has about one free turn in it before it stops, two MAX with a good spin. they actually do have a lot of resistance.

To each ones own, If I don't just pull it off entirely next time around I'll gut the sucker as the condensor and tubing is already off. 25lbs off the front end is 25lbs off the front end. Up north where I live now AC is redundant, zero humidity and a cool breeze off lake Superior.

And your setup explains why your engine revs so quickly and freely. But on a 2.2 there's many other areas to improve upon first before removing an item such as the a/c system which can and will devalue the car even more than just being a cobalt will do. Not to mention potentially contaminate the system which would make future reinstall more difficult.
I just honestly dont recommend it. When I was younger I ripped a ton of a/c systems off cars. Never felt much difference if any. Though the engine bays looked much cleaner. But that was about it. Then I was left suffering without a/c and reinstalling it was far more effort than removing it
I realize the op's doesnt currently work. But I think hes just making more work for himself down the road or making it harder to sell the car down the road.

You have to disassemble the Compressor, like Spike pictures above. Aside from fabricating an idler pulley to go in its place, that's the only way to do it when S/C'd, iirc.
Turbo or N/A can just completely delete the pump and throw on the shorter, non-A/C belt.
