Under what circumstances does the 292 crank breakage problem occur? I'm asking because I don't know. I haven't broken one yet in my stroker and would like not to break one.
My guess is it occurs at a certain rpm(s) and worst case is holding that rpm over time. Like a 1 ton truck on the highway for example.
And further, what damper choice has been shown effective to reduce breakage risk? I ran a SBC StreetDampr on my last build.
And lastly, which cranks are the worst? I read somewhere that the early steel 6 weights are the worst, maybe because lower internal damping of the steel material really let's it ring? Plus the bending loads of 6 weight versus 12 weight? The steel forging sure is attractive versus nodular if the harmonics can be controlled.
Some technical data on this subject from General Motors would be great if it's available. Real world experience equally valuable.
