NST Nissan 370Z VQ37HR & 350Z VQ35HR (07-08) Pulley Kit


The new HR 350Z and 370Z are Nissan's newest offerings in a long line of great performance machines. These two engines, the VQ35HR and VQ37HR, share the same pulleys and we decided to see if we could improve on these great cars by providing a bit of weight reduction in the rotating assembly.

The NST Nissan 370Z VQ37HR Pulley Kit 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. And to make things even better,
the NST Nissan 370Z VQ37HR Pulley Kit is compatible with the OEM Nissan belt.

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: Red or Graphite Gray.

The guys at carboy in Houston did the professional install and ran the dynojet for us. The gains are quite noticeable as shown on the dyno chart bellow. HP & TQ delivery, throttle response, fuel economy, and overall daily driving is enhanced due to the great weight reduction and the small, very conservative, amount of underdriving.

As you look at the charts you can see that the increase in power is shown from 0 all the way to redline (7200 rpm). Max power increased by roughly 5whp and max torque increased by roughly 6wtq. It is important to point out that the gains are even better in the mid (4000 - 5000rpm) range... gains here are roughly 10whp and 12wtq. NO OTHER $200 kit or any bolt-on mod will provide such gains!!!!

All dynos were ran on the same dyno, on the same day, with NO OTHER modifications, adjustments, or changes made. These numbers are 100% legitimate and repeatable.
