Easiest Way If Found without Having Recalculate Everything is just turn up torque scale you want something that powerful start buy doubling it current 1.75 change it to 3.50 try it see if that's enough if not take it up some more or if to much take it back down some

<motor torqueScale="1.75" minRpm="1000" maxRpm="3580" brakeForce="2.5" lowBrakeForceScale="0.22" lowBrakeForceSpeedLimit="1" minForwardGearRatio="10" maxForwardGearRatio="40" minBackwardGearRatio="27.5" maxBackwardGearRatio="50">
<torque normRpm="0.1" torque="0.35"/>
<torque normRpm="0.3" torque="0.45"/>
<torque normRpm="0.4" torque="0.60"/>
<torque normRpm="0.5" torque="0.75"/>
<torque normRpm="0.6" torque="0.85"/>
<torque normRpm="0.75" torque="1"/>
<torque normRpm="1" torque="0.85"/>
</motor>
