4.8s on both of your tms Jim?
4.8 on the 570, 5.3 on the blue line 525cfm according to old blower specs.
I like 12 flow but don't always use it.
I'll use a lower flow on burbur and in the winter.
But I have a 570 and a 405.
My guys love the 8 flow 14 inch west pac I may have converted it to 12 flow.
