I have never found Charlie to be anything but helpful. He is knowledgeable and makes a great product. If you try to just slap some of his parts on, and not follow his advice, I can see how he might be reluctant to sell a "upgrade" that is incomplete. He will be blamed when your system does not work well.

The real issue with all the G body AC systems from the factory is completely inadequate condenser capacity. Just add condenser capacity and it will work. The front condenser and rear condenser are the only stock components left on my car. OK, the fan housings brackets are stock, but that does not affect performance.

To try to make the 911 AC system work in hot conditions with just two compressors is jut not likely. The fender condensers are the real answer. Yea they weigh a few pounds, but the heat for the system is blow out the fender and not into the engine. Oil temps go down as well as the interior temps.

Bottom line, the few extra pounds of AC components make no signifigant difference in a street car, but the comfort of driving on a REALLY hot day make the car just a blast to drive regardless of the weather. In F1 those few pounds of weight would be critical. I am not ever remotely that good of a driver, and I sure don't drive at 10/10th even on a track.
