YJ AC-to-compressed air conversion question

I wanted to free up a few more HP's in my 4-banger by taking the ac compressor out of commission. Is there a way to remove the compressor and still use the serpentine belt? It doesn't look possible to me. I'm not sure how I could get more hp's out of the engine without disconnecting it.

While researching this I saw where a member mentioned converting an ac compressor into an air compressor for arb and airing up tires. But I can't find a write-up in the forum. Any ideas??

I'm also going to install an electric fan when I replace the leaky radiator and I read where that will give you extra power by removing the belt driven fan.

This is a 95 YJ I-4 manual tranny. Everything is all stock on the jeep.

Converting the A/C to OBA has been done numerous times, I believe there's at least one write up in the YJ FAQ's. There's not going to be a difference in having the compressor in place or having an idler there, they both will spin freely under load with no loss of power unless of course the compressor is on. I think the best bet for removing it totally is getting the idlers from a salvage. I'm sure some four banger guys here with no A/C can post pics of how it looks.
