air oil separator and smoke issues

[Kirk]

Just as an additional, related note - I've got a Greddy air/oil separator that was an aftermarket bit I had installed on a previously owned Subaru WRX. I spent a couple hours seeing if I could install that in my '00 Boxster S in-line after the OEM AOS. The idea would be to have a redundant system in case the OEM unit fails the Greddy unit would pick up the oil and has a visible sight glass to let you see if it's filling up with oil.

Well bottom line is that the Boxster engine bay is EXTREMELY tight. There's just no room for extras like this. My best option was to mount it in the rear trunk next to the coolant tank and run hoses through the firewall. I've got other projects to work on for now, so I put this on hold for the moment, but I'll see about picking it up again later. Not a priority though as I don't really see a redundant system here as necessary. I'm just playing with parts that I already have.

the mantis guys routed the AOS to a catch can rather than into the throttle body. i believe it somehow runs back into the crank case.

Cool... do you know where they mounted the catch can? This sounds similar to what I had planned with the Greddy catch can I have. Basically disconnect the line from the AOS to the intake plenum and attach the catch can in between. You could maybe blow it off to atmosphere (illegal in Cali where I live though) and let the catch can drain in the crankcase, or you could just route the outlet hose back into the intake.

i saw their test rig at road atlanta two years ago; it was some ghetto milk jug setup. their car is a cayman racer; the milk jug was mounted in the stripped out trunk area. not sure what their final setup looks like. you can email stan carmichael or ernie jacobowski at mantissport.ca; maybe they'll give some details. they may even sell their setup.
