NST (NonStopTuning) 370Z VQ37HR Pulley Kit Review w/ Dyno Charts

I also have to say that I bet the 370Z is more efficient and won't share these same gains as the 350Z. Would be a lot more interested if someone

Would be a lot more interested if someone would try these pulleys on a 370Z.

The more HP and TQ an engine makes, the more lightweight underdrive pulleys can free up.

Just for reference, the dyno chart from our latest R&D project, the BMW 335i...

That is the worst looking dyno graph I have ever seen in the 13 years I have been involved in getting my cars dynoed. Is that erratic power and torque as well as curve typical behavior for of a BMW engine???

Not entirely sure. This was the first 335i we have put on a dyno, and it was not running the OEM BMW map. But one thing is clear, the NST pulley made a noticeable difference across the RPM band.

We'll be testing with a bone stock 335i in the next couple weeks and will compare the behavior.

I got mine from O'Reilly Auto Parts. They didn't have any in stock, but ordered one.

BTW... I received the pulleys and hope to install it next week.
