NST Crank Pulley Reliability?

[ozmdd]

I'm done with this debate. As garm accurately noted many posts ago, camell isn't going to change his thinking, nor is he willing to hear anyone else. Apparently he believes he has some outrageous level of automotive engineering knowledge that far exceeds everyone else on the forum, and we're all idiots who have no experience whatsoever. Judging from his posts, I'd guess he spends most of his time doing exactly what he's doing here; sitting in front of a computer.
I personally have been taking engines apart and modifying cars for 26 years, when I bought and rebuilt my first car, a VW Fastback, so "yes", I know a thing or 2 about engines and how they function. I have a degree in Applied Physics and one in Environmental Geology, so I feel comfortable with numbers and forces. One does not need to be an automotive design engineer (which I doubt Camell is) to understand the relatively-simple forces involved in the internal combustion engine.
I think bashing (yes, your ongoing tirade against NST is "bashing") a vendor with good products and a desire to serve a relatively-small community (Yarii) and the folks who sell the products because you've learned a few cool engineering phrases online is pointless and sad. I do not believe camell is attempting to do a public service by repeatedly questioning the NST pulley. If camell is so sure about the need for a dampened pulley, then he should design and build one, then market it head-to-head against NST.
OUT.

OUT.

Why would he do that when Toyota has already done it with the OE pulley? I think camell has some points here. I have spoken to and built multiple engines and have always opted to build and balance the motor with the stock (dampened pulley). None of these motors are from Toyota but they have been 4 cylinder, high revving powerplants. Although the noise might seem miniscule, so are engine and bearing clearances and unless a motor is torn down often for inspection, there is no way to tell what the reality is. Many racers (who race with lightweight crank pulleys) will NOT recommend their usage for the street. That, in and of itself, tells a story...
