Just to help you, torque in an engine is measure by the combustion load on the pistons (average) times the crank throw IE force x distance.
Moment of intertia is something very different but that's another school day all together
So by Rich's logic you are now going to put a heavier flywheel on your car and perhaps some heavier wheels and you will see a gain in torque? Bear in mind until now Rich didn't know how torque is measured and was confusing moment of inertia for something else...
I've had enough anyway, it feels like I have to explain this to someone once or twice a month when it's just very basic physics that 12 year old kids learn in school and yet still many people can't get their head around it.
