How much HP does the A/C drain?

WOT will have the compressor turn off, so I cannot imagine you could measure the difference. I would say ~1% for AC. It's such a small difference there is no MPG improvement free with it on or off.

Having the a/c compressor turn off at WOT is best but a lot of older Hondas didn't do that. I'm not sure if the S2000 did this or not.

Oh it certainly cuts out. Go for a [legal] high speed cruise one night and at about 95-105 Mph the revs are 5-6k, and you will start to get very, very hot inside that car. The A/C clutch disengages to prevent rapid wear. Any vehicle that has a rev range like the s2000 would be wise to incorporate this feature.

Plus, like starchland said, there's no free power. Even if you could do it with an electric motor, it would just transfer the load to your alternator.
