Calculation notes
Each dyno point becomes wheel force at the corresponding road speed in every gear.
F = T × gear × final drive ÷ radius
Wheel-basis torque is referenced to engine RPM. No additional drivetrain loss is applied.
Equal-force crossings
Geometric intersections only. Shift time, traction, and engine limits also matter.
