P337 Intercooler Flight Test Comparison

[JamesC]

Walter I really appreciate your input - LOP ops certainly become easier given the simpler relationship between fuel flow and HP in that regime. Much safer than choosing CHT targets particularly at cold altitudes.
For ROP your formula leads to 100 % power at max RPM and MP.
However AA placards 35.3 " MP for takeoff power - was this based on HP dyno measurements or math ?
Even if there is exhaust back pressure, could the peak cylinder PSI's still not be too high at 37 "MP full rich with the extra O2 from the colder denser intercooler air?
Thanks very much.
