I mean, the turbo isn't that big. The housing and everything are basically the same size at the FP Green. XR Red and Red are different sizes. That of the XR being smaller with a more efficient wheel and ball bearing not journal bearing. So I actually think this would be more ideal for altitude than the Red.

My FP Green is hitting 24psi by 4200rpm, and I'm guessing this XR would make more boost at the same rpm range.
