How will a different balancer fix that problem?:dontknow:
To consider:
http://www.atiracing.com/products/dampers/damper_dinan.htm
and a quote from Jim McFarland; ..."what must also be considered is that the most damaging loads on a connecting rod do not occur during the pure compression of combustion. The oscillatory vibration of a crankshaft causes connecting rods to experience compression and tensile loads, alternatively, during every rotation of the crank. Esssentially, they become rubber bands that must withstand these cyclical load patterns while maintaining sufficient dimensional integrity to not fail or cause piston/head contact or bearing damage.." end quote.
According to Childs & Albert (rod manufacturers), in NINETY PERCENT of the cases they have evaluated, rods don't fail during compressive loads. Rods
can fail during detonation but it
isn't common. They most often fail when they are yanked back from TDC during the exhaust stroke. END.
Personally, I haven't seen how these rods are breaking- Small end?, big end?, beam? (no one has mentioned bolts yet) and that is why I asked these questions earlier. Are the manual tranny guys having the most failures from blowing the 2nd to 3rd shift and over revving? Does the piston top have major signs of detonation? I do know if detonation was that severe, you would see it in the bearing as well as other places (ie. ring lands).
In a massed produced engine, I'm sure they don't put a special defective rod in the #3 or #5 hole of every Viper engine. Something causes it to fail there. Harmonics inside a 10 cylinder engine with a 97 pound crank might be a good place to look. Just a guess thats all...
