LOL some of the things the military experiment with on the 2 strokes made absolutely no rhyme or reason.Walter those marine engine have almost the same PSI of boost as the highway engines
Double EagleA marine 8v71 has the same volume as any 8v71. If boost psi is the same, the difference in horsepower would come from at what rpm the peak torque is measured. Using the formula HP= (RPM X T) / 5252 if you raise where the peak torque is measured from 1600 rpm to 2400 rpm you would also raise the horsepower by 50%.Matt
