Thank you for your post/research, echo. Always good to compare.

I will have to second everyone's opinion on the Redmax 7500/8500. I own both of these blowers along with the Stihl BR600. They're all great blowers. The Redmax 8500 blows the hardest, the Stihl BR600 is the lightest and the best on fuel but hands down, my favourite blower is the Redmax 7500 which I just got in May. It blows harder than the BR600 but not as much as the 8500. However, it's lighter, uses less gas, and scours the pavement and turf much better than the 8500. I don't use the 8500 that much anymore unless I have large debris to move.

Just curious on about how long is the breaking period ( tanks of gas)for the redmax blowers? I bought a new 7500 redmax a few days ago and really so no difference in power than my br600's. it's brand new so hoping the power increases in the next few weeks??

When I bought mu Husky 570 I felt about the same way, though I could see a difference. I didn't care though because I was happy with the power of the 600 up to that time and had just wanted a 2 stroke due to their simplicity. After I got to use the 570 on more and more stuff I quickly realized it was a lot more blower than my 600. Usually 5-10 tanks full to really get broken in. Still, you should see a difference between the 7500 and the 600 even if the 7500 is new. What are you blowing to compare them on? Once you get into large piles of leaves or other heavy debris it's no contest, the 7500 will leave the 600 in the dust (Pun intended).

Used it just cleaning leaves off driveways right now as only had it 2 days. Today was a rain day and put a little weight in one of the green landscape barrels in the shop and was blowing it across the floor. Used both blowers side by side and really no difference. The redmax sounds more powerful and grunts more but didn't see much of a difference. Maybe I will have to get in a big pile of leaves to see the difference.

Unless you happened to get a bad one, you'll see soon enough. After about 5-6 tanks of fuel I really started seeing the difference. I ran both side by side on heavy fall leaves for two seasons and have had lots of opportunities to see them try to move the same material pile. When the leaves get deep enough and heavy enough in the pile and the 600 will no longer move them effectively, the 570 (7500) keeps right on moving it. They are both great blowers, but the 7500 is clearly a lot more on real world debris.

Another good test I've put them both to at the same time is blowing heavy sand and gravel from ditches that the snow plows always throw in during winter. They both do great, but again, I can clean crap out with the 570 that the 600 started struggling to do.

The 600 is much better on fuel, but since the 570/7500 holds a lot more fuel in the tank, they will both go just about exactly the same amount of time at WOT. I've tested that over and over again.

If you were to cut that flare at the bottom of the inside radius, you'd basically have the tube end that is on the 7500/570. Trust me when I tell you, the 7500/570 fan isn't overworking the engine in the slightest. It operates at a minimum of 750 rpm's below its maximum rated power speed (max rated power speed= 8000 rpm's vs maximum operating speed of 7250 rpm's). The 8500/580 on the other hand, actually operates at its maximum rated power speed of 7200 rpm's.
I'll say that if EVERYTHING was the same (engine size/HP/impeller design?) except for the tube tips...then I could wrap my mind around this concept.

So what would happen if the 7500 tube tip was put on the 8500? Too much backpressure...&/or a possible 250mph air speed???
