Default How much HP does the A/C drain?

Anyone have any numbers on how much power the a/c drains? Obviously you can feel it, but has anyone ever done a dyno run with it on and off?

Something like 50hp. But it's only to the front wheels.

I've done it on other Hondas, they will all be somewhat close and around 8whp, that was on a fwd Honda, most Hondas should be in the 5-8 whp range if the compressor doesn't shut down at WOT.

I agree, you an definitely feel it, and generally speaking you can't feel anything under 5 hp, so it is definitely in the 8-10 hp range.
