I think in the end when looking at dynos, it's all about relativity anyway (non-einsteinian) - the graphs mean the most when comparing the same car before/after mods/tuning.  |
Yes, the as vehicle speed and engine load increases so does torque and therefor friction. The more friction you have the more heat you have, thus higher drivetrain loss the higher in the RPM band you go. Another reason why it's good to have torque down low so its more useful than torque in the higher rpms.
