There will almost certainly be more latency/lag with a larger wheel, but this also depends on the motor being used. These motors get to full speed very quickly even under load and I suspect there is more to the issues Shiv was seeing with the TQ300 then just lag.

I think a big key to mitigating this is variable seed control of the motor, rather then the full throttle all or nothing system that the Phantom system uses.

-Intelligent speed controllers that can sense and adapt to load conditions and do things like soft starts

-Closed loop control to reach a target boost value rather then max boost possible

-Starting partial boost at partial throttle (say 80%) and raising as throttle increases.

The main reason I started this thread is because people were wanting to experiment with more advanced control and power features like this. I'm hoping that in terms of the motor/compressor hardware we can come up with a really solid easy to build design that people can then use to experiment with.
