the crank shaft its harmonic balance?

Those links are detailing the replacement a traditional rubber dampener or viscous. What needs to be proven is if our stock crank pulley dampens anything having to do with dangerous frequencies. I find little merit in the rubber gasket quelling any vibration at all, it's too small. The only difference I see is one is iron, the others are billet (some may be cast) aluminum.

There is already a thread on this whole topic, this should just be merged with that one. Waste of forum space IMO, there are no revelations here. Even the links are the same.

Are you kidding?? The first article specifically talks about how solid crank pulleys are bad. The second article covers every single detail in harmonics and even shows how you test for it. TORSIOGRAPH
Maybe you need to actually read them, or find better data than that proving it wrong...

Maybe you should have read the original thread, and if we have a harmonic balancer, damper, dampened pulley, whatever name you want to give it, wouldn't you see one on the car? Look at the crank pulley, remove the damn thing and look at it, there is nothing about it that dampens harmonics. It keeps the motor from dropping revs too fast, just like the stock flywheel in an attempt to keep drivability in tact.

Data is in the numbers. Name or show one, just a single VQ37VHR motor that had catastrophic failure that was absolutely, without a fraction of a doubt caused by an aftermarket crank pulley that was installed correctly. Do you really think I would come into a debate and not do my homework on why you argue against light weight pulleys? Only a fool debates without research. Show me concrete evidence. BTW, I've read both links before you posted them a while ago. There is no talk of an undampened crank pulley with the exception of low RPM V8's.

I reckon your the one that needs to do some more reading before you blast my posts. This isn't the 90's anymore, engine's evolve.
