Wow, car is now running, got dynoed with 345 HP at the shop who flashed my the DME, will pick it up tomorrow.
That's more than I expected at that stage.
This is with the stock 987 exhaust, stock MAF and airfilter housing, plus a simple to-be-improved connection between throttle and MAF.
Thus around 10 HP missing because of a interim-hose connection to the MAF, around 10-15 HP more could be made with an improved exhaust (which is underway).
Anyone got an idea if there is a proper throttle to MAF/arifilter connector available?
I stepped across the IPD Plenum for 3.4 engines, and this seems to be the hose I'm looking for - I might consider the plenum as well but not sure it is appropriate for a 3.8 engine and it's connectors..
Is there any such hose like on this picture available (in ONE piece, no more connectors) which would fit my 3.8 conversion? Inside diameters are 80mm at the throttle side, 89mm at the MAF side.
I don't like my current solution consisting of 3 connected pieces (80 degress angle, 80-89mm connector etc)
