Overview of the Stihl BR 800 X MAGNUM®
- Power: The BR 800 X MAGNUM® gas-powered blower, manufactured by Stihl, is rated for a max air volume of 912 cubic feet per minute (CFM) and a max air speed of 239 MPH.
- Handling: Like most backpack blowers, this model is technically heavier than a handheld. That being said, it can feel lighter and more comfortable because of the way it is carried, even when used over extended periods of time. Its throttle is located on the tube, which allows you to keep your left hand free. At 23 lbs, the Stihl BR 800 X MAGNUM® is within the average weight range of gas-powered backpack blowers.
- Engine: This blower is fitted with a 79.9cc 4-Mix engine. Stihl's 4-Mix engine is a 4-stroke engine that runs with a mixture of oil and gas (50:1 ratio). You can find more details about this technology further down the page.
- Speed Settings: There are times when you only need a little more power, while other times you will want a bit more precision when clearing leaves and debris. For this purpose, the BR 800 X MAGNUM® offers variable speed settings, adding you, the user, more control, and a cruise control mode, which will allow you to maintain it comfortably for as long as you wish.
- Noise: Its noise level of 78 dB falls within the expected range for gas-powered backpack blowers.
- Fuel Tank: With a capacity of 67.6 fl. oz., this Stihl blower is average compared to other gas backpack blowers.

- Upon exiting the nozzle, the air can reach speeds of up to 239 MPH, which is rather impressive for a gas-powered backpack blower. If you wish to benefit from air expelled at the fastest possible speed, the Husqvarna 150BT and its 270 MPH could be an option to consider.
- If air volume is an important feature, the BR 800 X MAGNUM® by Stihl will not disappoint. Its airflow maxes out at 912 CFM (cubic feet per minute), which is more powerful than most gas-powered backpack blowers. If air volume is important to you, the Husqvarna 590BTS, with 1245 CFM, could be in your good books.

4-Mix Engine Technology
Stihl's 4-Mix engine combines the advantages of 2-cycle and 4-cycle engines. This award-winning 4-stroke engine runs on a mix of gasoline and oil (1:50). For this to happen, the gasoline-oil mix enters the cylinder head through a bypass channel in order to offer full lubrication, which avoids the need for parts like an oil pump, sump or tank (which are compulsory for traditional 4-stroke engines). Therefore, there is no oil servicing to do (easy maintenance), the leaf blower is lighter (due to fewer parts) and its overall noise is lower. Additionally, all 4-MIX engines are fitted with a system that considerably reduces the effort needed to pull the starter rope.
The bottom line
- In the expected price range
- Cruise control
- 4-Mix Engine
- High CFM (912 CFM)
- High MPH (239 MPH)
- Decent weight (23 lbs)
- Decent tank (67.6 fl. oz.)

Bought mine in November. It’s March now it’s in the shop tore apart, waiting on parts maybe just get the runaround from customer support and tech. It never ran right right from the start. One run around after the other warranty is nonexistent would never buy another Stihl
Not a great carburetor for cold Canadian winter usage. Maybe fine on milder climates. Moved a lot of snow when running at peak rpm but weather will affect the carburetor performance and rpm’s may drop while in use due to fuel mixture not quite right for -30°C or colder air temperatures. Have to retune the carburetor for different ambient temperatures which is irksome to maintain peak performance. Only used it in the winter following factory storage instructions for the summer. Carburetor likely works well in milder climates like I’m Germany and the USA but falters in performance in Canadian Winters when weather changes can be 20°C or more from one day to the next in the winter. Otherwise a nice machine the 800X.
The BR 800 is a mighty machine. It is well-designed with high-quality craftsmanship. It comes on quickly and is very easy to use it.
I love STIHL BR 800 X MAGNUM High Quality I have used STIHL products for years
The weight of the blower is well distributed and being 2-3 pounds lighter than other similar backpacks means my wife or I can use it easily for an hour on several acres we maintain. It can blow 2″ gravel like its sand and deep leaves go 20 feet. We will never need to rake again. I didnt know about the 4 stroke until now, its very light and grunts, meaning you can set 20% throttle and tap the trigger when you need the boost. that makes it more quiet and not having the high pitch 2stroke whine. its VERY well thought out. it is thirstier than our 15hp mower per hour, but that means its even lighter, burning off the fuel. Im very very happy with ours. didnt have trouble starting it. It does use 89+ octane with mix, and it has a winter slide under the air filter that we will need to use if there is snow to blow. Again, @240mph, and 912cfm we will never touch a shovel again. it can lift an 8″ round, 2″ thick rock and move it away at full throttle. Stihl quality is worth the price. dont stop part of the way there. and it has residual value too if you sell your property.
Got one in February 2019,only used it for about 4 month as I do not need it in the Summer,had always problem starting,needed at least 6 to 8 pulls and when it was cold up to 20 pulls,had it in the shop 3 times when they put on a new carburetor,still under warranty,helped some what,still problems starting,and now the recoil broke.Don’t think I by another Stihl ,maybe try some other brands.I do not recommend this one.However,it does have great power.
