wtf does comparing peek hp matter when your primarily concerned about the torque curve? Any engine, doesn't matter if it's 2 or 4 stroke that has a better torque curve that start early in the usable rpm range and stays flat over over a wide rom band is going to better then an engine with a crappy short torque curve that peeks and drops off.Yeah and they are worthless in the feild or with long bars.
Please tell us how having a peak horsepower number relates to a chainsaw with a long bar cutting large logs? The saw doesn't run anywhere near your peak numbers but please proceed.
Any dyni worth a crap will make that as plane as day comparing different t engine or modifications to the same engine. Bar size doesn't matter, chain sharpness doesn't matter, operator doesn't matter on the dyno. Learn to read the data.
