Guys it is a clarification! Given that I noticed this kind of vacuum, accelerating gradually up to 3000giri and for this reason increased a around the shaft of the geometry (and then adding pressure, even if, in reality, the peaks were always those), I have a doubt! It is not that the geometry is too closed? Thus in addition to return in the position of oartenza, I have to try to decrease still? It almost seems as the face is the stopper, and then with the opening of the geometry to 3000 rpm vent and that extra push! Instead of being linear!
Do you believe this is possible?

in case it is too open however, in rereading your previous posts I think you confused absolute pressure with relative. What you see from the log of the edf, you always have to remove the mbar of atmospheric pressure that normally have a value of 1000. Then you on your log if you read 2500 mbar pressure measured in reality your turbine is 1.5 bar

Yesterday I riposizioneto the screw geometry as when it is retracted from the review, that content, unfortunately, is a accentuamento of the tome lament, that is, by accelerating gradually, the salt of the rpm up around 3000, and then have a moment of uncertainty and immediately after one shot of power!
For the pressure, it may be that I have misunderstood, but I understood the speech pressure, absolute and relative, of the time for bad habit, my say example 2.6 bar when the turbine compresses to 1.6, is an error in my expression, but I understood the meaning.

In any case, unfortunately I do not understand why it happens to me all the time and I still of the high peaks, is if I close further the geometry if I put it away "as revision", then the speech that could make a plug for is bullshit? I'm thinking of all of them.
