Are today's 4-strokes more powerful than the old 2-strokes?

[QUOTE="DaleH, post: 380861, member: 15636"] Well, the truth is ... WHERE the torque curve lies IS a factor in performance, but at WOT ... HP is HP, less all of us only realize 90% of that if/when using ethanol-based fuels. Many also may not realize that the motor YOU buy can be +/- 10% of the labled horsepower by Federal law. Years ago, when you saw OMC Stinger or High Output 'HO' motors, those are motors at the HIGH end of the rated HP band. FWIW I worked at GE making jet engines for the Apache and Blackhawk helicopter lines and motors with highest HP were called "boomers" and were reserved for special operations duty. [/QUOTE]
