## Caption

Fifteen percent drivetrain loss isn't a real number. Parasitic loss is friction — gear mesh, bearing drag, oil churn, accessories, tire squish on the drum — and friction doesn't scale with your turbo. Add STD vs SAE J1349 correction and inertia vs load-bearing dynos on top of that, and the sheet becomes an opinion. Your butt is measuring wheel torque in second gear. Chase area under the curve.
