Subject: RE: Cummins 855 boost pressure



first,  if it's  leaking  20 psi off somewhere,  it would be pretty evident.

900*  at  full power?    That  doesn't seem too far out of line to me.    
Even then,  do you trust that pyrometer?
  Just to  make sure we are talking the same language... full power is full fuel,  and engine lugged back to 'rated speed'... Not setting the  fuel TO rated speed-  


What's the exhaust smoke  looking like under these conditions?   Slight haze, or  verge of  blackening out the sun?  
What's the condition of the  exhaust system?   Muffler  good shape; not rusted shut or coked up?   
1000% certain you got the timing correct?  
But like the other guy said,  knowing which 855 and how it's fueled would be nice to know.
