yep, turbine blade design makes a huge difference in turbine whistle... it's not purely blade count as some 10 blades whistle like crazy where others don't. an HT3B has a 12 blade wheel, and it whistles like crazy
obviously, spinning it faster at idle with a VVT/VGT will compound the effect, but the wheel is the difference, not the number of vanes in the VVT section
