Makes sense but they never mentioned "boost pressure" or if they even had a gauge. Sadly you get the feeling the object was simply to see what (5) blowers would do. I have that same model Husky Blower, my inclination is it is made for volume not pressure. Just holding your hand over the outlet indicates it can not build pressure. One thing that might have been interesting is to run the blowers in line, not to add volume but make pressure and see if ithey could build boost. Where/How they dealt with all the 2-stroke exhaust is not shown.
