Maximum horsepower to run safely LOP is determined by peak combustion=20 pressures which gives us a maximum percentage of rated power IO-550=20 310x.65=3D202hp. Lets say we increase the horse power to 350hp with 10= :1=20 pistons, flow balance, etc. Do we have new power curves? Can we safely= run=20 LOP at 350x.65=3D228hp? does the higher compression create even higher peak=20 combustion pressures so we must lower the maximums? Do we have to operate=20 farther LOP to compensate for the higher compression?=20
