I have the complete set up from a 2007 cayman S, Air Box to intake T. Still doing my homework on this, just trying to lay out my options before I do the install. I'm busy with school rite now and I have suspension upgrades planed for spring break so this project is on the back burner until I can more info on the update. My main concern about this is the MAF and what I may need in the way of programing in order to benefit from more air. I would like to take advantage of the flap in the intake t for low end torque. If the intake flap is actuated with the variocam I may try hijacking the signal from the variocam solenoid relay to actuate a relay for the additional vacuum solenoid. I may put it off until I can get some head work done. I recently saw a post on the Pelican Bord from someone who had adapters made to use the cayman S intake manifold on 996 heads.
In case you can't tell I got a real bad case of cant leave well enough alone!
