I actually got a response back by email from Hayward after I sent them an email last week.
They responded that for the "SP15922s, the amp draw is 11 on high speed and 2.0 on low speed, voltage is also 115v."
So actually the Hayward 1hp is slightly more efficient at low speed @ 2.0 amps vice the 2.6 for the Pentiar Dynamo 3/4hp or 2.9 for the Pentair Dynamo 1hp

Decisions, decisions......
