Effect of AC on engine output?

Well to find out what the power loss really is (and for absolutelly no other reason at all ) I have booked my car for a RR session next week... so Im taking donations to help with the cost
Any refrigeration/ac system will increase duty as pressure and tempreture rise, and so therefore the % of power taken will rise accordingly. Just to throw a theoretical spanner in the works, doing a RR with a/c on/off will tell you the power taken to drive the a/c at a specific temp, ie the cabin and outside temp. If you were to then move all the kit outside on a hot day, lets say 28 degrees with the car in direct sunlight etc, the duty on the compressor will be higher, pedantic I know, but if an experiment is worth doing.

If it's hot I turn it on.
If it's not I don't.

The issue with some turbocharged cars is that the intercooler is sandwiched between the ac condenser and radiator. Once you turn on the ac the condenser gets hot and reduces the efficiency of the intercooler and air intake temps will rise. Higher intake temps mean reduced performance.
