The volumetric and adiabatic efficiencies both increase at all RPMs. You would see the power increase on a non-intercooled application using the same pulley. You would be less pressed to use an intercooler or smaller pulley, but the gains would still be there. This leads me full circle back to the 10% I was talking about. The coating just goes after that last bit of efficiency left on the table inside the current unit.

Sounds good, thanks for the response. I'm a fan of maximizing things to the full extent possible. Now, I have one final question:
With this new coating, are there any clearance or reliability issues when used in very cold environments? I'm thinking of condensation that freezes inside the rotor housing and turns into a layer of frost. This frost would likely be thin but would certainly be greater than the clearances. Would this be an issue for this new coating, or even the standard 210 without the coating?
