Damn, I can not find a document with torques I got from the list, but it seems to me I remember numbers correctly.  It
said 15 ft/lb and it was too much - I broke the shaft.  Guys from turbo shop who balanced the second shaft told me
that they use 7 ft/lb.  I followed their advise and after 5K mi  it did not fall off yet.  I used blue locktite.
