IntelliFlow 4x160 over Whisperflo?

Designing a new IG residential pool. I am digging through posts on this topic but I wanted to post my own pool specs (still in the design phase).

Is it worth paying an extra $750 to upgrade from a Whisperflo pump to the IntelliFlow 4x160?

My main factors are energy savings if I can take advantage of some of the lower settings on the Intelliflow but still keep the pool clean. I will have a separate blower for the spa. I will also have a legend pool cleaner with its own 3/4hp pump.

85' perimiter IG pool
420 sq foot of pool surface
Approx 13225 gallons
16' perimeter attached spa
51 sq foot of spa surface
2 skimmers with separate runs to pump
4 surface returns
Pentair 420SF Cartridge Filter

Thanks for you input.

Sorry but is not as easy as that, could be a savings and then again may not show a ROI for 3 years. What control system are you using?
The 4x160 offers some efficiency increase over the Whisper flow, but the Full Intelliflo may be a better option if you have the right Intellitouch control system.

4x160 and Intelliflo discussion is a hot topic now for Chem geek, go read his thread on Pump Efficiency .

What are your energy cost or Rates per Kw Hr? (usually posted on the power company website)
Solar?
Plans for expansion?
Go here and do some fast research on daily operation cost

Energy costs are 13 cents per KW. No solar. No plans for expansion.

I havent picked any automated control system at this point. The builders std pool pkg doesnt include digital automation just a analog timer for both pool pump and cleaner pump. The more expensive pump may be overkill for my small pool. Thanks
