In short, this information is not
suggesting that these turbos should be running at 24psi peak and 17 by redline. Peak efficiency is well below these figures.
I think we are definitely stating the SAME things here. I stated we need efficiency information and to use the engines displacement, rpm and volumetric efficiency to plot where end users are pushing these turbos. If someone can get the efficiency percentages I can do all of the other calcs. Lastly all the data I posted was compressor outlet pressures NOT intake manifold pressure.
