    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.
