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!  |
I intend on manufacturing a press fit sleeve for the 987 MAF housing. To bring it down to where the 986 tune can work with air flow. This diameter nicely matches the dia of the 987 74mm tb. This way I avoid custom programming issues
The 987 T flap is vacum operated. It may be that the vario cam change overs their signals could be made to run the flap and work but I fear you will get snap change in flap position as the cams phase (2500 rpm ?). Maybe this is okay as this a coast cruise rpm but if the phasing occurs at (4000rpm) you could be in the middle of a corner when you get cams and flap changing.....whomp!
The 987 would have vario cam plus which is gradual.
Sounds interesting let us know how you make out!
