The comprehensive NST pulley thread has numerous pages filled with countless first hand reviews from Z owners who have actually used NST pulleys in the real world...
NST (NonStopTuning) 370Z VQ37HR Pulley Kit Review w/ Dyno Charts
None of these owners have ever experienced any electrical issues, weak accessory output, pump failure, or engine failure when using our product. The reasons for why NST pulleys perform as well as they do, can be found in the same thread.
In addition, there are many threads on other forums where Nissan, Honda, Toyota, Scion, VW, BMW, etc. owners have posted their first hand, real world, reviews and experiences with NST pulleys. 99.999999% positive.
Not all pulleys are created the same, and no other pulley is an NST pulley.
