We recently 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.
From the NonStopTuning website:
The NonStopTuning Nissan 370Z (G37) VQ37HR Pulley Kit (NST13710K) increases horsepower via great weight reduction and the underdriving of accessories. Superior to other available kits, NST kits also offer an Overdrive Alternator Pulley to optimize output for stereo system lovers.
The NST Pulley kit drives the alternator at OEM speeds, no slower, no faster. As a result, there is no need to worry about dimming lights, weak batteries, or weak alternator output.
Each kit is carefully crafted from 6061-T6 aircraft aluminum, tested and balanced to high tolerances. Every NST pulley is hard anodized for exceptional durability and is available in a choice of colors.
The NST Nissan 370Z VQ37HR Pulley Kit is also compatible with the Infiniti G37 and the Nissan 350Z HR.
