I am putting together an Excel spreadsheet that the flow requirements of the Duramax at different temperatures, altitudes, RPMs, and HP levels to determine the optimal turbo efficiency map as well as compare the stock map to what we are really doing. There are a few bits of information that I still do not have that would help finish the spreadsheet. Does nayone know any of the following specifications.


Max turbine speed
PSI drop from torbo outlet to intake inlet
Intercooler Efficiency %
Engine Efficiency % (ignoring boost)
