Still new to the nuances of the blowers. I keep seeing the Gen V references. What did it come on? Anyone know the differences from a Gen 4? I saw a u tube vid about a ported Gen V and it did have some different shapes in the air inlet where it goes over the edge into the rotors. But I didn't know if it was a design change in the Gen V compared to a Gen 4 or if the guy had made the change during the porting??? Thanks for any info on the Gen V.
