Sure you could gripe about it not being actually attached to the crank during the balance procedure but in reality it does not matter one bit. Flywheels are very thin compared to a crankshaft. You would see that the equations end up as very minor amounts <0.5 gram, even considering ridiculous porosity in a casting.</strong><hr></blockquote>
IF we were talking about the differences between flywheels OR the differences between flexplates.....there could be a small diffence (maybe grams) but he is talking well over 10 pounds or more difference between a flexplate and a manual shift flywheel. Most stock 168 tooth (14") flywheels weigh over 30 pounds.
