We had a chance to dyno test one of the most popular NonStopTuning Pulley Kits on one of the most popular and most fun cars on the road today. The Nissan 370Z is the latest in a line of cars with a great deal of heritage and a legacy for high performance.
Enough with the text, you’re here for photos and dyno charts!
All before and after dynos were performed on the Carboy Racing Dynojet in Houston, Texas. Before and after dynos were performed on the same day, with pulley install in between, with NO other modifications of any kind. Numbers are listed as uncorrected figures, temps and humidity are also listed. All photos were taken during this testing session.
Conclusion? NST Pulleys improve power, torque, and response across the entire power band. If you look at the area under the power and torque curves you will notice positive gains in the low, mid, and high range when the NST Pulley Kit is used. No other modification in the same price range can offer similar gains across the entire power band. This fact makes the NST Pulley Kit one of the best bang per buck performance modifications for the Infiniti G37 and Nissan 370Z.
