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.
