The little info I can find online seems to indicate that SPL on pumps is sort of like Peak ratings on audio amplifiers. Its calculated at the point of turn on and seems to be the measurement of power it takes to get that coil spinning up to speed not the power at constant speed.

Either way, I seemed to think that the pump was too much for the filter, not underpowered so what ever the actual output of mine is, it seems fine.

Actually its rather annoying as when I clean the strainer with the pump running.. it tends to start pulling in air from the strainer sans basket. But changing the strainer with the pump off is messy so I just try to do it quickly and make sure there is ample water in the pool.
