Well, I was able to get hooked up with a new Et Low Boost wheel this past week. I have been running the Riva B1 but I have read that boost tapers off and maxes out at 11.5 once you hit 7700. The ET wheel should hit closer to 13 near 8400 rpms which is where I would like to be spinning.
Looking at the 2 side by side you can see the difference in blade height, the amount of blades, and the shape in which they curve. Et is the gold wheel, Riva is black.
