Torque rise is what most people are actually talking about when they say torque/lugging power or get thinking that a 5HP electric motor makes more power than a 5 HP gasoline motor. Compare a two stroke Detroit diesel to a four stroke Cat of the same HP. The Detroit will up shift through the gears and is still pullIing hard when it hits the max rpm governor. The Cat as it approaches redline is falling flat and running out of "pulling power as volumetric efficiency is rapidly dropping as rpm increases. The airflow path and cam timing can not fully fill the cylinders. Take any short cam timed, small port engine and dyno the rapid drop in torque as it approaches peak HP rpm. Thus also a very rapid and pronounced torque rise as the engine is lugged down from peak HP rPms.
