Which Flywheel???
The light flywheel will allow the motor to rpm faster. The heavier flywheel will store more energy to leave hard but will punish you at the big end. If your car bogs off the line, the heavier one may help. If your car spins off the line, the light one will help at both ends.
Just the facts.
