4.08 gears and Lightened Flywheel

Flywheels have a little weight on them for a reason I was more or less just curious enough to do the swap. If i ever unbolt the tranny again I will be going back to the OEM flywheel. I ran at the strip with a buddy of mine too after the swap and we were both right around the same numbers in the 1/8 mile no big differences. Save your self the money IMO.

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.
