Back late to the party, had a couple busy days. Yes I verified in my notes that the 1400cc/30sec figure was for the -007 at the injectors. When testing the system we use the injector volume, when testing the pumps we use the fuel distributor inlet volume. These numbers overlap when you are looking at anything from 2.4L 911 to modified 3.3L 930.
Reading your last post, you are saying that at idle flow rate the WCP is 3.4bar (50psi) and plate down WCP shoots up to 4.2bar (61psi)? Can you apply 1.0bar pressure to the WUR side port and record the BoostCP? It needs to get down around 2.0bar to feed your power level I would think.
The -007 does not function well if adjusted wide open. You get into tuning and balance issues. You might back the settings to where they were previously (if you have them marked or recorded the revolutions) and see what happens. As you know, each port is not an island, movement of one port affects the flow of the other 5. Lets get the BoostCP number first and go from there.
