relationships visible.
10 configurable engineering reference tables. Change an input and compare the pattern across a useful range.
Every table states its units, method and assumptions. These are calculations, not manufacturer fitment or rating charts.
Chain pitch & travel reference
Compare pin-to-pin pitch with chain travel per driving sprocket revolution.

Tire diameter & revolutions reference
Compare geometric revolutions per mile and kilometer for different tire diameters.

Torque, RPM & power reference
See how power changes with shaft speed while holding the entered torque constant.

Drivetrain loss sensitivity table
Compare wheel-power scenarios across selected loss assumptions.

Quarter-mile weight sensitivity
Hold engine power constant and compare an empirical ET model at different race weights.

Converter operating-point comparison
Compare hypothetical converter reductions with a fixed chain drive and engine RPM.

Jackshaft stage combinations
Compare second-stage reductions while keeping the first chain stage fixed.

Road speed & engine RPM reference
Compare engine RPM across road speeds using total reduction and nominal tire diameter.

Tire aspect ratio comparison
Hold section width and rim designation constant while varying nominal sidewall aspect ratio.

Sprocket tooth count & pitch circle
Compare pitch circle diameter and average pitch advance for a selected chain pitch.
