You will need one that is balanced for 28oz, either a new one or yours rebalanced.

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.(?)
The unbalance factor is independent of the actual weight of the flywheel, so definitely spec out a 28 ounce unbalance factor (as opposed to 0 or 50)
