So im getting my build under way, and have come to wonder "why dont we have harmonic balancers?"

Im sure that someone is going to chime in "an inline 4 is inherently balance." But that has nothing to do with torsion vibrations from the chuffing of the cylinders.

Have any of the bug race homies snapped crankshafts before? Are there crankshaft preparations that i should pay to have done prior to assembly? Cryo maybe?

Thank you all for the help and support!
