They are using a WY platform Walbro. At 80 cc they are maxing out the pump capacity of the carburetor, so there’s not room for much loss of pumping performance.
I can’t imagine that blowers will get much more powerful than this simply because the human body can handle only so much. But I did see that Husqvarna is launching a bigger one, or maybe already has, at 56 newtons vs 48 for the 9010.
