Hi,

Technically, you're correct. But, also realize that the Compressor on the Boxster is a variable pressure type and can be running anywhere between 5%-100% of rated output depending upon demand (Ambient Temp and desired Temp Setting).

This is to both enhance Range (MPG), and maximize Perfomance (reduced parasitic power loss). But, I think we can all assume that running the AC Top DOWN on a warm day will have it operating at, or near, 100%.

Also, remember to run your AC at least 2 min./mo. (top UP or DOWN) to circulate the Compressor Oil though the system for both the Compressor and also to delay drying out of the 'O' rings.

It's certainly true about the Sweat Sox in the Vent system though...

Happy Motoring!... Jim'99
