Minimal on our test car (2009 370Z) honestly the power gains on an NA application are not there. We are working with Kinetix on a revised runner length and design to see if anything more can be gained. We hope to know more once we're able to test on an HR 350Z.

Since you have this on the car and took it to Z-Dayz, I assume you tuned the car with this on there. Where are the dyno sheets?
We tuned it in house with Osiris, but as I stated earlier the NA power gains were minimal, not a lot of use in posting dyno charts that don't really show any thing of value at this point. Keep in mind that the unit on our 370Z is a prototype that we bought from Kinetix for testing purposes before making a large investment in a stock order.
HR people get over it. The stock design is pretty efficient. I think Nissan engineers learned a lesson from the DE design.
Agreed. Most of the DE gains were simply from uneven cylinder filling. Once that was alleviated the remaining gains from spectacular designs were minimal at best.
