MoreThanDyno

Use cases:

• Finding optimal shift points
• Recalculate top speed when changing gear ratio
• Comparing vehicle acceleration
• Comparing torque on engines with different redline

The different graphs:

• Thrust compensated for weight and air resistance. Wheel power/weight - air resistance.

• Thrust to weight ratio Wheel power/weight useful when gps top speed or drag is missing.

• Raw thrust Wheel power. Intereseting when comparing engine characteristics from vehicles with very different weights.

• Engine power/torque normalized by rpm Adds a gearbox to every engine and ensure that the outgoing axle spins at the same speed for all engines compared.

• Engine torque normalized by rpm Adds a gearbox to every engine and ensure that the outgoing axle spins at the same speed for all engines compared.

• Engine power / Engine Torque The traditional dyno graphs

• Optimal shifting Shows the power band for each gear and when to shift.

• All gears Shows the wheel torque for all gears in a stacked graph

Example use case - recalculate top speed when changing gear ratios.

Add your vehicle, be sure to set top speed, but do not fill in drag. Drag will be calculated from top speed and vice versa.

Clone your vehicle, remove the top speed but leave drag. Change gear ratios to whatever you see fit. A new top speed will be calculated from the current gearing.

Hint: For maximum top speed, you want the top speed to be at the rpm that your engine produces the maximum power.

TODO: Accumulate input power from x > 50 until y < 0 Accumulation must happen in the same steps.
