Variable Speed pump "sizing" and how do I figure it out

[kelemvor]

My Hayward EcoStar SVRS has a sicker on it that says: 2.0HP, 1.35 SF, 2.7 THP if this helps at all - I realize this info is not on the Hayward website so I figured I'd share.

Thanks very much. Sounds like the motor its-self is a little less powerful than what I've got, perhaps the impeller is better. I have no idea what my wet end is rated at, there's no markings on the pump that I can see other than the ones on the motor (which I replaced last year). I think maybe I'll try to find it local in the event it won't run the spa I could return it. My usual pool store wants $250 more than most sites online do, though.
