Aaah John Deere B, been a long time since I seen one. My dad and brothers would leave an old tin can over the exhaust to keep water out, then see how far it would fly when you started it… simple pleasures. LOL
Did Jeep use the exact same carb, intake and exact same exhaust as Buick and used the exact same dyno on the exact same day with the exact same weather?? You get my point, too many variables to blame the difference all on the heavier flywheel.
The flywheel and pressure plate assembly on my Scirocco weights 15.75 lbs (might include the kennedy 4 puck disk too, screwed up on my notes on that. My other lightened flywheel and pressure plate assm weighs 5 lbs more. The light weight and the solid 4 puck makes engaging the clutch smoothly more difficult when leaving a red light. Once engaged, it will rev up and down much faster. I built this car to autocross, not to be comfy leaving a red light.
What are your goals?
Street car, leave it stock is cheapest option and you know how that feels.
Slightly lighter, remove the outer lip beyond the ring gear. Most lightened flywheels are like that, and run a stock disk. The 4 puck with no springs it too “on-off” for street starts. It will accelerate faster with lighter flywheel.
I would like someone to prove to me how more weight will accelerate faster beyond the initial launch. It defies the laws of physics.
