[QUOTE="F8L SN8K, post: 10948866, member: 50367"] Sitting in freshman orientation at Rose-Hulman with my brother and friends always made a lasting impression on me has the instructor demonstrated for all the families Moment of Interia. The reason why I'm using Moment of Inertia is because that is what is important. 2 flywheels with the same weight and same diameter can have different MOI as the mass can be distributed differently(closer or further from the center. Also do not assume that a lighter flywheel as a lower MOI as it's not always the case and vise versa. This is where pressure plates/flywheels make or break you in the performance world. And choosing the proper one for your car is important when extracting all out performance. Not as big of a deal for DD street cars but still has an effect on performance and drivability. Remember acceleration is the change of speed and/or direction. So "deceleration" of a flywheel is also slower with a higher moment of inertia. Meaning it is harder for the FW to slow down to match the speed of clutch disc actually making it harder on the clutch without aggressive clutch materials or higher pressure plate force. So IF the RPM was the same between the two was the same a lighter FW would actually be able to match the speed quicker causing less wear. However as mentioned earlier it takes about 200-300 more RPM to match or overcome the higher MOI flywheel/pressure plate kinetic energy so the difference in speed between the flywheel/pressure plate and the clutch disc/transmission will be greater so it's ALMOST a catch 22 depending on other factors. So another downside of a lower MOI is the car will have the RPMs pulled down faster. However the engine will also recover faster with the lower MOI flywheel. Remember there should be no slip in a clutch system(except for clutchless transmissions clutch system) so once the clutch is engaged all preceived benefits of a higher MOI flywheel are lost. [/QUOTE]
