Anyone having experiences with the catch can slip ring loosening over time? Had to tighten mine a few times already. Not under the assumption I need to pull out the channel locks... Wouldn't consider myself to have a weak grip. Product is doing its job as described saved myself at least 2 tablespoons of self ingestion over the past month. Overall, very happy with it. Potential air leak as well? Very difficult to hear over all the engine noise but hearing a hissing around the a/o. No CEL codes

I have done a few track days now and haven't really noticed any smoke. That said, I have seen smoke from ZaxF before.
We also noticed the other week that one of the fittings on Meanstreak's ISF had snapped. Maybe he just got unlucky. It would probably be a good idea for you guys to check them every so often.

I'm hoping that is the case. The T-fitting that cracked was related to the air intake setup not the AOS though. It was where the small filter attaches to the valve cover breather tubes. I have no idea how this could have broken unless the filter was in a bind against the firewall. BTW - I contacted RR and they quickly shipped replacement parts at no charge so kudos to the customer service.
As far as the AOS goes - the most immediate thing I noticed was that my car no longer hesitated around the 5000 rpm mark. It has always done so during repeated thrashings so I assumed it was just inherent. The "lag" was also apparent on my dyno charts where the HP stalls around 4800 and then takes off again above 5200. Perhaps the ECU was pulling timing. I don't have any data to substantiate but that would be my guess. After installing the AOS, it seems to pull very smooth and hard all the way to redline every time. If I get a chance to re-dyno I will see if there is any change in the shape of the curve. I've put about 400 miles on it (mostly interstate going down and back to Road Atlanta) and it has collected maybe 2 tablespoons of oil. I look forward to seeing what it does when I finally get the rocket on the track.

Actually, the AOS system has nothing to do with the valve cover breathers. It is a stand alone system that connects in line with the existing PCV system and will work with the stock valve cover venting system which connects back to the intake. The RR Racing intake vents the valve covers to atmosphere which is where the small breather comes into play and the cracked fitting we were discussing. These two systems work well together but can be installed independently.
