By working the other way from engine torque, I think that I can answer my own question 😯
Using data of another car that I have, engine has 225 N.m max torque, TG ratio = 1.03, diff ratio = 4.39 (so overall ratio = 4.5217) then max wheel torque in TG = 225 * 4.52 = 1017 N.m
The max Force at tyre edge in TG = max wheel torque in TG divided by wheel radius (to tyre edge, 0.3 metres in this case)
So max Force at tyre edge in TG = 1017 / 0.3 = 3391 N = 345 kg.f
So all I need to do is measure the radius to tyre edge, get the nominal kg.f pass value for the wheel, convert that to Newtons, multiply that figure by the radius, and that’s the torque to apply and see if the brakes can hold it ?
