all values at 12 volts unless otherwise specified:

Code:
1 CIM  at 45 amps         =  295.6 watts @ 3586 rpm

2 CIM  at 38 amps (total) =  295.6 watts @ 4645 rpm

2 CIM  at 45 amps (total) =  347.6 watts @ 4503 rpm

2 CIM  at 45 amps (total) =  283.2 watts @ 3586 rpm  at 9.97 volts

all calcs are approximate. # of digits does not imply real-world accuracy
