What He actually wants to say is that an engine with 95 psi cranking compression can be lugged down to lower RPM without damage than one with High compression. The Hi PSI engine would probably detonate and blow holes in the engine. But to make any noticable difference You'd have to increase the compression ratio like from 6.5:1 to 7.5:1 or so. You will reach a point where your fuel will not support the higher heat and compression and will detonate & destroy your engine. With these old engines like the H's & M's you would have to modify the engine for much higher compression, and lug the snot out of them down to like 500 to 800 RPM at full load. The higher comp. pressure actually does give more Horse power.
