4.08 gears and Lightened Flywheel

Zensation

True but half The idea behind reducing the weight of the flywheel is that more torque will reach the wheels due to less rotating mass on the crank. Its just that most of the losses from crank power to wheel power occur in the gearing of the transmission itself. And your right the throttle response increase is due to the same reason because there is less weight on the crank. I notice it if the clutch is pressed the engine spools up quicker but again if im driving the time it takes to go from 2000 rpm to 7000 rpm probably hasnt changed. Idk for sure bc i havnt clocked it. All i really noticed is its sometimes annoying to start moving from a stop.
