There are some cars that don't have a 1:1 ratio.
I am trying to model a Formula Student car which has a bike engine so the lowest ratio is 1.86 which is nowhere near a 1:1. The maximum torque we got on the dyno was 44 Nm. I want to know what torque the engine produces at its flywheel but I can't divide by gear ratios as that would give me a false torque now. I doubt the person running the dyno tests knew the gear ratios so I was wondering how the dyno gave a torque of 44 Nm which is pretty close to what other people have got with the same engine.
