The engine's delay, or "spool-up time", is controlled by the <bypassratio> number. Increase the <bypassratio> number to increase the delay. The thrust table called "MilThrust" contains the values of thrust versus mach and altitude. This is for 100% throttle. The turbine model causes thrust to vary with rpm-squared for partial-throttle operation.
