Lightweight flywheels For NA: Pros and Cons

You guys must be coming from more of a mechanical engineering side talking about your inertia/"moment". I've always taken a more mathmatical/physics approach is why I mentioned torque. We are talking the same thing here.

All the lightweight FWs that I have used have always made improvements. Drivablility did change a bit, but nothing difficult at all. You do gain acceleration by going lighter. As B/TTT mentioned, I would do it again if I had anything with a stock FW.

^^^ Aerospace Engineering, but isn't engineering just the application of mathematics/physics?

Moment = torque. Inertia is something entirely different, but I'm sure you know that. The only reason you have to give it more gas to get the car going is because it takes a certain amount of energy to get a 2900 lb car moving. Mass and rotational speed are independent, directly proportional variables of that energy so if you decrease one, you have to increase the other.
