I think having the electric drive with no lag issues and coming on so early in the rpm band throws away traditional needs to be conservative on wheels sizes. I wonder if a different wheel can be used in this system to get the extra air needed if so desired.
I also don't really know what I'm talking about, just really reading to learn and throwing ideas out there.

Well... you have been misinformed.
Don't take it from me, look at any compressor map of a large wheel (ex.T76). The surge line occurs @ higher flow rates, making it a very poor choice for low and mid engine rpm's for a ~200 HP engine.
There are other ESC being developed with real engineering. Choice promotes excellence.
