Stock Nissan 370Z Dynos 258whp
Our new 2009 Nissan 370Z was strapped down to our “heart breaker” Dyno Dynamics dynamometer for the first of many dyno sessions. The heart of the 370Z, a 3.7L VQ37 HR engine, drew a beautiful dyno curve and produced 258whp.
For reference, here are some comparison figures from stock Zs on our dyno:
2003 Non-Revup 350Z: 215whp
2006 Revup 350Z: 234whp
2009 VQ37VHR 370Z: 258whp
The rich AFR looks promising for gains with an Injected Performance reflash or Haltech Platinum 350Z EMS - both of which will be tested in the near future. Please see the dyno chart and video below.
