on THIS car. little shit like D/S, trans tune, gears, tire wear even tire pressure can add up to make a noticeable difference

it’s not me that’s the 1/2 tard, it’s you that’s the full fledged 'tard.

@underboosted

Less rotating mass equals less tourqe. Been researching this for weeks with flywheel weights for my wrangler to give it more low end. Tourqe is what’s gonna get you off the line faster. Just sayin.

Plausible, but at what point does it stop. Heavier wheels, to move this discussion down the driveline, wouldn’t apply more torque to the ground once the limit of adhesion has been reached, right?

Where underboosted is going with flywheel weight is applied torque to the drivetrain and then the wheels.

IE 4.0 spinning a 30 vs 21 lb wheel will have more torque to apply to the driveline when you let the clutch out, due to the additional energy created by spinning the heavier mass. The other side of the coin is the engine has to produce more energy to spin the heavier wheel. Optimal flywheel weight really depends on vehicle intended use and complete drivetrain setup.

Also skid the caddy should have an aluminum DS from GM. They use aluminum on all the DS and torque tubes for reduced rotating mass. However it’s done to improve highway fuel economy 0.01 or w.e. MPG. In the real world aluminum vs. steel no real difference on quarter mile performance in a 13 sec 6k pound car. It’s like the difference of a spare tire in the trunk or not.
