| :then some engineer sitting behind a desk. I'm an engineering student at UT and have worked at a car tuning shop and in an office job at Shell with engineers and will be working at NASA next fall. Keep in mind you're still a student. You'll find out soon enough that not all engineers are desk jockeys. My engine builder is also a mechanical engineer, and he thinks solid hub pullies are bad Engineers think they know it all, and they are smart people, however there is something more to be said for the people that work on it first hand in the real world everyday (especially when is comes to tuning cars). Enough with the blanket statements. Not all engineers are that way. Although I've had more than my fair share of hands-on experience, I'll be the first to admit that I have *much* to learn. At the shop we would have engineers that are getting their cars done and they would be telling the guys this won't work and this will etc etc etc. The techs just kind of knod along and do what they do best, and this is how they make a superior product. Sure. I've seen this before firsthand as well. And just for your own engineers 0WN arguement, do you completely ignore the engineers that design the light weight pulleys in the first place? What do the all coveted Nissan engineers know that they do not? I imagine Nissan engineers have done there fair share of NVH analysis and reliability testing. It would be a waste of money for them to spec a harmonic balancer for every engine if they thought it was unnecessary. Any OEM powertrain engineer is going to design with reliability in mind, whereas aftermarket companies place performance ahead of reliability. Removing the harmonic absolutely will cause more torsional vibrations. The question is whether or not these increased vibrations will cause damage. I'd rather not take the risk, so I chose a fisher pulley instead of a solid hub pulley. I still stick to my opinion that this whole thing started with some bimmer that may or may not have blown its engine due to a lightweight pulley (on an I6 for the record) and all the internet tools that think they know everything followed by jumping on the bandwagon. You're certainly entitled to your opinion, right or wrong. Are you calling me an internet tool?
