Trying new airboxes and intake on my z06 with the Harrop Hurricane

Awesome results! I’m still keeping my hopes up for stateside testing - big cam, higher CR, and e85.
I'm trying to organize something like that right now. A big cam is alright, but a cam specifically designed for this runner length would be better... I actually have one sitting in my trunk, just not sure if I should pull the trigger in having it installed.
I finally got the final dyno results with the complete Hurricane/FluiX setup at good weather. The power increased by about 10-15 hp above 4500 RPM. The first image shows this dyno run. On the second image I plotted all important data on one plot for easier comparison between the old intake/intake manifold setup vs. the Harrop/FluiX one.
The dip is most likely when the pressure waves in the intake runners reach the inlet of the runners, instead of reaching the intake valve. That point should be the worst timing in between the 4th and the 3rd reversion. The 2nd reversion would kick in at 7500 RPM. The smaller dips along the way could be the reversions in the headers. The lower you go on the reversion number, the higher their effect will be, but same goes for when you hit the spot in between the reversions.
