Cylinder pressure is enthalpy, using that enthalpy requires matching energy exchange rates, which takes piston acceleration, or lots of RPM. The other side of the coin is pumping losses. I can discuss ideals, but there is so much needed to reach those ideals that is just not possible with what we have to work with.

Whoa, I was thinking in more simple terms. Make a run at let’s say 20psi of boost and 18deg of timing. Record peek cylinder pressure. Now pill timing and add boost to get back to that peek number and see what happens to hp. If it goes up pull more timing and add more boost.... that type of thing. All the while keeping an eye on egt’s, exhaust back pressure... try different fuels and different iat’s.
Is cylinder pressure even the limiting factor for one of these engines?
