In turbos, variable geometry vanes surrounding the turbine can optimize exhaust flow and pressure to provide near instananeous boost across the entire throttle and rpm range.
How about on the compressor side?
Can variable vanes work in the compressor impeller?
Una?
Some other rocket scientist in the house?
Well, doing it on the compression end would actually create variable amounts of flow that would make it difficult to get the intake runners to the correct size.
Once you handle the turbine side by using variable geometry, you solved alot of the problem. At low exhaust speed/volunme, boost is enhanced and more linear with the boost at high exhaust speed/volume, which allows you to choose the best intake set up.
It seems like you would only need to manage it on one side of the turbo.
Now, on a supercharger, I think you would want to address it from the compressor side.
