I have one of these, running 9S (1800mAh) on 3W-25/Wemo Combo. Pretty quick on 1300W, and sounds great, but remember that is has long ducting which robs efficiency:

Also, the intake shape is not great - the mock shock cones are probably causing some turbulence and further loss of efficiency.

IMO, one needs to consider nacelle-type setup or very short ducting. Erik van Schaik has some good concepts - check out his works.
