Mythbuster did a show on using your a/c compared to having your windows down. The car with the windows down ran out of gas first. That show is pretty good!

My Z has the best performing 134A system I have ever seen.

I try use 'natural' cooling as much as possible. Using AC not only eats more gas, it takes away 50hp
and drains the battery.
Most annoying is that engine is not as responsive with the AC on. I can feel hesitation esp at light throttle. I have to adjust clutch engagement by giving it more gas.

Ya man I know what your saying. When I drive, I like to save gas, so I roll down the window. Try holding out you arm at an angle so the air flows into your car. Works for me?
Wha-La

If it is 75 degrees out, and your are comfortable at 75 , you better roll the windows up and set the air conditioning to 75 . Nissan could have added 50 pounds of insulation to isolate the interior, but chose not to.

"Urban puzzle": it is more efficient, on a hot day, to run with the A/C on and windows up than to run with windows down (b/c of increasing car's drag).
Computer-based mpg measurements:
11.7/11.8 with A/C on and windows up
11.7/11.8 with A/C off and windows up
11.3 with A/C off and windows down
So, according to the computer, it's better to use A/C with windows up.

Who has hit that resonant frequency in the Z that causes the pulsating?
It pounds your head
Recipe:
drive at 60-65mph with driver window only down, no passenger, you will hear it.

I have notice in manual mode that if you idle for long period of time in temp over 100 degrees the A/C automatically shuts down. If you keep the car moving or turn that system to auto it will cycle the system and keep cooling.
I think in manual mode there is an overide at idle in manual mode to make sure your not stressing the engine after 5 mins of idle. I noticed this when I was viewing houses. I would sit out front making my notes on the properties and then the A/C would blow hot. The wife and me thought the dang thing broke. We got the car up to 30mph .... and froze our butt off. It took us an hour to figure it out in 112 degree weather. That was not a happy day. ;(
What do you guys think? Have you noticed this? I like to put it into manual to lower the fan. If you keep the system in auto and don't turn it up pass 75 it freezes you out.
