    As for the Redmax 8000 as 203 mph air speed 688 CFM at the pipe looks good to me .AS for the weigh of the tube you must be joking that's not enough for nothing I use a 23lb. backpack and a 10.5 handheld at the same time.

    Some of my favorite "toys" are/were made in Japan and there is NO lack of quality/ingenuity. "German engineering" is hype and nothing more. Get over it!

    Now I see you have totally different numbers for the Redmax. The 720 cfm for the Dolmar is at the housing...the cfm at the tubes for the Makita is 526, which I presume is the same for the Dolmar...that's pretty weak by todays standards. I calculate the Dolmar to be 36% less powerful than the 8000, that's pretty significant.

    PS...if you got a real blower you wouldn't need to use a handlheld along with it, lol.

    dolmar products are really robin so they are jap made-not german. usually i prefer jap also but the shindy 4 strokes are terriable. they should never have been sold till they were prefected. a huge stain on shindy,s reputation.

    The Dolmar has 3.8hp get through your head !at is the same as a Husqvarna560BFS it has 3.81 hp 632.13 cfm 232.42 mph A blind men could see that's close to the same as the Dolmar (720 cfm) (195 mph)and has for the Makita is 526cfm in the post "I have them and to be honest it is not far behind the 8000 redmax! I can do more in a day with it than I can the redmax 8000because it is a couple of pounds lighter! It is a whole lot easier on the back!"
    One of their engineers at Makita
    "He thought that the published Makita numbers were too conservative and suggested Makita might be correcting these specs"Do I need to keep going on ?

    Bottom line I can find hundreds of post than have some thing to say bad about Stihl I can't find one bad post on a Dolmar ....

    HP does not necessarily translate into either mph or cfm. Listen...get it through your head...you're using the wrong cfm number...that is at the housing, not the end of the pipe. Makita reports the same 720 at the housing but also report it at the tube. If you want to believe that they somehow defy the laws of physics and get the same cfm at the tube as at the housing then yes, they are close in power...but the facts don't seem to support that.

    From the numbers I have seen the Dolmar does not have comparable power output to the Husky 560. The best indication of the power of the units is a calculation of their power index, which you get by multiplying the cfm by the mph and then dividing by 10,000. So you've got 526 x 195 = 10.25 for the Makita/Dolmar. For the Husky 560 you've got 632 x 232 = 14.7. 14.7/10.25 makes the 560 43% more powerful. Now compare it to the Husky 580/Redmax 8500 with 908 cfm at 206 mph, giving a power index of 18.7...that's 82% more powerful than the Dolmar/Makita. Sorry but there's just no comparison.

    I don't care what you buy or what you use but I don't want other people basing their decisions on false criteria. And again...the weight given for the Dolmar/Makita is without the tubes on dude...yeah they're only plastic but they aren't weightless.

    Fly-


    HP means not much when you look at blowers. The BR600 and Husky 570 both are righ at 4 HP, but the Husky is a LOT more blower than the 600. It is all in the design of the fan itself, and the size/shapes of the tubes. I have both, and I know first hand.

    If you want a dolmar, get one, but don't try to make it into something that it isn't just to make yourself feel good. Instead of speculating about them or reading BS on the net, go run them side by side on the same debris at the same exact time. You will see the difference, no question.


    What Darryl is trying to get across to you is exactly right. You just need to listen. Dealers and manu's will always try to make their stuff sound better. They're trying to make a sale.

    Don't say that to a Stihl dealer. I asked my dealer about Stihl making a bigger blower. He looked at me like I had two heads. Then he said that there would be no point since Stihl already has the baddest blower on the market. I didn't say another word.
