It appears the trick is going to be making the damper work at whatever RPM and sequence of impulses the firing order inputs to the crankshaft. I have run several race engines totally without a damper, mostly on boats, but we expected to scatter a few engines as a consequence of the abuse we gave them. I don't recall breaking any crankshafts, though. The 3 main bearing flathead V8's we ran on the dirt track broke cranks pretty regularly, but they were running a 3/8" longer stroke than stock at 50% higher RPM than the factory designed them to run. They were also getting hammered from open to closed throttle several times a lap and running 11:1 compression and alcohol. It looks like the only way to see if the idea will work will be to do some extensive dyno testing. Fortunately, I'm equipped to do that with a little setup work.
