bfsc,s .i don,t really pay much attention to them now that we have a/f ratio measurements at our disposal.before we had a/f ratio on the dyno we paid more attention to egt,s and bfsc,s.on another note,it is common practice to prop a boat above max hp rpm and the boat will almost always go faster that way.
