C'mon guys - any fool knows that the Tornado must be placed on the SUCTION side of the leaf blower to obtain full effect of the vortice-inducing blades. Placing it at the outlet reduces it's effectiveness by 57.3298572957295837%, according to my calculations.

Now if you put a tiny, little, itty, bitty tornado - more like mini-me tornado - on the tiny, little, itty, bitty two stroke carburetor that powers the leaf blower, then you can pick up a few more ponies due to the extra leaf blower boost produced by that little 2-stroke ring-a-ding-dinger leaf blower motor making more HP.
