We'll call it instant tourque. With a lighter flywheel, you have less Mass (what is it, Mass x Force = Energy?), but the engine is making the same Force. So, the lighter flywheel (or anything fastened to the crank) makes it easier to stall the motor, as it is ultimately imparting less Energy to the clutch disk. You could negate this reduction of "instant tourque" by lightening the rest of the car, including unsprung weight. (I'm sure it'll take more than 14.5 lbs.) Numericly higher gears may aleviate that effect too. The car is Inertia, which is a product of weight and friction-resistance.(?)88_stanga said:yea i am in the process of ordering the flywheel and balancer. i found a flywheel the other day that weighed 28 pounds but found one today thats 13.5 so i dunno which i should go with. i heard i lose tq with a lighter weight flywheel...true?
