Yes, I agree that is the typical function. The challenge to the engineer is to abstract from this to the presented task. There is no requirement/law that the second mass be directly connected to the driveshaft.Dan Timberlake wrote: ↑Sun Oct 04, 2020 12:06 pm I believe dual mass flywheels' typical function is to smooth out the power delivery "out the back" at low loads and heavy throttle especially with engines with few cylinders. Variations in instantaneous rpm. Not to tame the crank twisting events.
The crankshaft is a consumable in this racing class. Design a crankshaft with dual snouts with the new snout being directly splined to the driveshaft u-joint. Make it a very expensive consumable.
No-one is going to pay for this.
If a wealthy competitor does and dominates the field then it will be prohibited by a rule.
