Impeller questions

Does anyone know;

Whats the Adiabatic Efficiency %?
Whats the (Efficient Max) Impeller RPM and the (Absolute Max) impeller RPM?
It doesn't say on their site.

max rpm is around 55k. I know not of what the max eff. rpm is, I just spin the crap out of it, and reap the benefits. It probably isn't the most efficient way, but it works for me.

Yeah, I wonder how the efficiencies compare....What is the inlet hole size? Discharge size?? Thanks!!!
