We know that:
1) AC runs off of the crank, so it saps a tiny bit of power as-is when in use
2) AC generates heat with all else equal

Please enlighten me on the other variable(s)
On the 911, the engine bay is very tight, and I imagine the cold AC lines might be near the intake manifold. Maybe I'm thinking of another car, but its something my mind recalled.

I've also always felt like the AC took away power, but maybe its helping the supercharger somehow. Very small chance, logically speaking, but I'll definitely try it on/off on my next dyno run
