I'm interested as well. The AOS doesn't quite handle the demands on track for me. I will eventually instal the Motorsport AOS but maybe a a catch can would be better.
On my Cayenne Turbo S, the crankcase ventilates to the driver's side intake and over time, fills that Intercooler with a significant amount of oil, and by significant, I mean that 1/2 qt or more can be poured out after 25,000 miles. This is common on the Cayenne and not Turbo blow-by as is sometimes the initial, incorrect diagnosis.
Anyway, I mention this because others have installed a Mishimoto catch can with good success and I've just purchased one myself, but haven't installed it yet. They're available on amazon.com and here's are a couple pics of the kit.
I had a Mishimoto OCC on my S2000 track car and it is a very fine piece of kit. High quality, would definitely go with them again for any 911 part. Just a heads up; be prepared to wait a while for a custom order. I recall it taking 2-3 months to get mine.
