405 vs 570 vac test.

It's a little misleading because I could set my relief on my 570 higher but.

405 results 100 foot hose run 2 25 foot 4 to the door to a devastator filter 25 feet of 2.5 inch hose to 50 feet of 2 inch hose.

570 running 6 ft of 2.5 into silver bullet then 25 feet of 2.5 to 75 feet of 2 inch hose.

I consider max lift ratings almost inconsequential. There are two lift numbers that are much more important. Lift reading after blocking the hose for 1 second, and most important is live lift reading during use. I could make a 33 blower go to 20" lift at 100' (it would require water injection at the blower) but it would have terrible recovery and live readings.

Both my 4.8 blower and 4.7 blower snap to max and the relief opens at the truck.

The 405 hose jumps around a little more.

The real point is to see at a 100 feet what I'm getting from each truck, which if they we're around 10 or less I would feel I was losing major suction somewhere.
