From Jeff240sx
...here is the cold, hard truth about the effects of a flywheel. Effective weight = .5 flywheel weight x ((FlywheelRadius x Gear x FinalDrive)/(TireRadius))^2 So. Lets plug in numbers. Our flywheels are what, 220mm or so. That's 8.66". Lets use that. Stock flywheels weigh what? Lets us 22 pounds, cuz some guy said 21-23. A Fidanza weighs 11, right? Finally, the tire is 24 inches, at 16" alloys, 205/50/16. 1st Gear: 5.5lbs x ((4.33" x 3.32 x 4.08)/(12"))^2 = 131 lbs lighter. 2nd gear = 43 lbs lighter 3rd gear = 20 lbs lighter 4th gear = almost 12 lbs lighter 5th gear = 6.8 lbs lighter. -Jeff |
