Not sure what the blower speed specs have to do with anything other than colors on a chart. Mine works great makes lots of boost and almost no heat. Efficiency is only as good as the total output. If efficiency is lower but net output still remains higher it still makes more power as long as heat isn't a problem and or bearings can't take the rpms. So far it all works great on mine.
