I think I get what your saying. My 460 has max HP around 9000 rpms. The torque continues to rise if I crank the flow valve tighter but the rpms are falling faster than the torque is increasing. Torque x rpm/ 5252 . Can't get HP without rpms or torque. I'll have to test the max torque its probably max at around 7 or 8 k
That's probably a whole study in itself for tuning a saw, not just the peak torque / rpm numbers, but what does the powerband look like? What does an ideal power band look like? how many rpm between peak torque and rpm? How do those old "torque monster" saws that people love look compared to a new high rpm pro-saw.
I've never seen a mnfr publish any torque / hp curves for comparison.
I generally consider the powerband of something to be between peak torque and peak hp....
I'd assume a saw with a wide power band (i.e. low peak torque rpm) would bog less, but have lower peak HP. After you're done with compression, breathing, and obvious mods, you can really only move the peak torque number around to increase HP... a saw with peak torque closer to peak rpm and a high rpm will naturally make great numbers, but not necessarilly be great in the wood... the minute you drop the rpm in a stiff cut it will fall below the torque curve and stall out.
I think this whole 2-stroke thing complicates it, you have a mechanical max rpm, a "breathing" max rpm (defined by ports and nature), wear and tear of higher rpm, and many factors to consider when tuning I guess. funny how 2-strokes are easier to manufacturer and maintain than 4-strokes but are so much harder to model!
