Jim,
Thanks for the work you have done on boost formulae, and the exacting
analyses.
I do not want to get into any discussion here on who is "more right" on
a simple statement about the order of magnitude of the boost issue. It's
simply too complex and inappropriate for this forum.
But------ if you carefully read my original message it says "Neglecting
thermal losses, of course."
This was meant as a statement of the gross theoretical potentials,
whereas your educational formulae makes a great use of the expression
"T2/T1", a compressor thermal rise due to adiabatic compression --
purposefully neglected in my statement for simplicity. Then you add
more "thermal losses" to get to what Doug admittedly stated was an
"inches of mercury" misspoken statement, not a psi boost statement. You
use centrifugal compressor examples, and the Miata accessory units I
drove were roots type compressors, not centrifugal turbos (not that it
is germane, here).
Peace, and lets try to keep the list to Tigers.
