Looking at these maps side by side, it is evident that there is little difference between them. The differences seen are well within the testing tolerances set by our laboratories. When the maps are combined, the similarities become even more pronounced.
So this is given the same wheel design. I'm not a hater, I just don't believe in the rediculous gains from a machined wheel over a cast one. What I am saying, is it is going to be much harder to spin a bigger wheel, that flows more. Bigger means more lag, not just boost onset, but lag.
