NonStopTuning recently had the opportunity to develop and dyno test a lightweight crank pulley for the Hyundai Veloster.  Our friend Alex’s peppy 1.6 liter NAV came to us as an unmolested car.  No performance mods of any kind meant that this NAV would be a perfect blank canvas for before and after comparisons.

No performance modifications other than the NST CR-Lite Crank Pulley, same dyno, same day.

The NST Lite series is a designation used for pulleys that are light-weight versions of their OEMcounterparts. All NST pulleys are built using High quality 6061-T6 aircraft aluminum and are easily 65% to 70% lighter than steel or cast iron OEM pulleys. Every NST pulley is hard anodized for exceptional durability and is a great item for use at the track or on the street.

OEM Veloster Crank Pulley – 48 oz
NST CR-Lite Crank Pulley – 14 oz

The NST CR-Lite Pulley is compatible with naturally aspirated, turbocharged, or supercharged applications, and is compatible with the OEM belt. No belt change is required when this crank pulley is used.

Both horsepower and torque numbers were consistently higher with the NST CR-Lite Crank Pulley.  Testing was performed in third and fourth gear, and max power and max torque were up by approximately 5 points in both cases.

Horsepower UP At All RPM

Torque UP At All RPM

Better Throttle Response, Quicker Acceleration

Looking at the graph plotted for Speed vs Time, we see that 110mph was reached faster with the NST CR-Lite Pulley.  The Veloster’s acceleration seems to have improved by about 1 second in this test.

Conclusion?  NST Pulleys improve power, torque, and response across the entire power band. Looking at the area under the power and torque curves you will notice positive gains in the low, mid, and high range when the NST Crank Pulley 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 one of the best bang per buck performance modifications for the Hyundai Veloster.
