Yes of course it changes it. Just saying that it is possible to base an estimate off a compressor map.
Just to be clear - estimate only. Change a variable and you have to recalculate it like anything else in the world.
As you said above you can't tell 90% of a TUNE from a dyno printout of WOT. You can estimate 90% of the vehicle's PERFORMANCE from a dyno printout, cause hey when you are wanting performance you are at WOT.
I don't disagree that hp is not essential, but as you keep repeating it is determined from the torque and rpm. So wouldn't looking at the torque graph be wise as a starting point since the hp is calculated from the torque?
On your Ducati plot, it is showing x-axis torque, z-axis rpm and y-axis ??? Is that meant to be BSFC? Is this a factory tune or aftermarket? There is a "flat spot" till a certain rpm (I can't read the axis label) so is this maximising or allowing for low rpm throttle control for take off/stability control/launch control? Since most of us are familiar with AWD cars, I am trying to eliminate variables specific to a bike.
Great discussion btw.
