At the time of its debut the Infiniti G35’s refined styling and sporty performance made a loud statement. Among other items, the G35 shared its VQ35DE engine with the 350Z and was a legitimate performer on the street and track. We had the opportunity to test the NonStopTuning Underdrive Pulley Kit on one of these cars and were pretty impressed by the results. Jessica’s G35 came to us as a completely stock car and provided us with a perfect blank canvas for testing.
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. Dyno graphs and max values are listed, temps and humidity are also listed. All photos were taken during this testing session.
Using a car with NO other performance modifications gives us a blank canvas and makes it abundantly clear that the gains we see are associated with the NST Pulley Kit. Our test car did better in terms of horsepower, torque, and response, as indicated by the upward shift in both the HP and TQ curves. Better horsepower and torque delivery is clearly visible in the low, mid, and high range of the power band.
Max horsepower went from 227 to 232, with a very nice shift in the mid range, posting consistent 10+ horsepower gains in the middle of the powerband. Max torque was more impressive with an increase from 220 to 232, delivering these gains pretty consistently across the entire power band.
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 G35 and Nissan 350Z.
