[Flightgear-flightmodel] Calculating MP?

[Cameron M. <li...@to...>]

I'm trying to model a small RC engine, but I don't know how to get the
Manifold Pressure.  I have the following information to work with right
now:

  desc         = O.S. 46 FX  <http://osengines.com/engines/fx.html>
  displacement = 0.455 (cu in)
  bore         = 0.870 (in)
  stroke       = 0.770 (in)
  min RPM      = 2000
  max RPM      = 17000
  max HP       = 1.59
  fuel flow    = 13.2 (oz/min)
  cycles       = 2

Is there a way to (roughly) calculate the min and max MP?  Google's
giving me nothing.  :-)  Thanks
