when considering conversion, vibration dampenning is obviously one of many important issues to consider, so I pose this question: shouldn't we use combined mass of the clutch disc and pressure plate as installed on the original engine together with an original flywheel in aircraft applications as well? Maybe even using the clutch disc whith it's spring dampenning system and input shaft from the trans through a redrive. I've read that the 3 cyl. geo has some ugly torsional vibrations at 1700, 3400 and 5100 RPM. I found it curious that the vibe monster reared its ugly head at those ranges. I understand the weight penalty, but if that could taim the monster, it may be worth it. Any thoughts?
