Now, you may ask, well why not bolt a 14-71 on a 454. Well, for two reasons. For starters, you'd be at a very low drive ratio. The negative result of that, can be simply inefficiency, especially at low rpm. The rotors turning too slow, can result in carryback. The other reason, is its simply taking alot of power to turn that large blower, when its not warranted. 20lbs of boost? Ok, now we might be getting close, but for the typical marine 5-8psi, it's just not needed.
Why cant my small blower work just fine?
Well, it can. To a point. What happens when you spin the blower too fast, is it creates heat. Lots of heat. Not only does heating the intake air charge, help invite detonation to the party, it kills power output. Lets say you have a small 174/177 blower just screaming back there. You may have intake manifold temps easily exceeding 200+ degrees. By simply going to a larger blower, say, 8-71, 420, 10-71, you may drop the temperature down 50, 75, or even more degrees. How much of a gain is that worth, well, think about how you're N/A car would run on a blistering 120* degree day, vs how it would run when its 60* at the track. There was an oso member, who converted his 575sci mercury engines that had the 256 superchargers, to 8-71's. With the same amount of boost in the manifold, he picked up around 5mph in his 40' outlaw. I, also personally switched from 250 blowers, to 420 blowers, and gained about the same in my 38 Fountain, again, at the same boost level.

You must be aware that using high-quality equipment helps in getting the job done right. But what about the right root blowers? How do they help? What work do they do? Here’s your complete guide to understanding root blowers, root blower manufacturer, type of roots blowers and much more.
Root blowers which are also known as positive displacement blowers are used in different industries widely. These are mainly designed to move the applications that require large volume of air/gas at low pressure levels. They are used in industries like the paper production, waste management, cement production, chemical processing and much more. While buying the right root blower it is necessary to ensure reliability, efficiency and optimal level of performance.
The root blowers are key to many industries as this is the equipment used to control air compression and make a balance. They have positive displacement systems that help in pumping fluids. To understand the types of root blower and the key factors while buying the right one, below is a mentioned detailed analysis.
Root blowers simply operate and comprise of two rotating lobes that spin in opposite direction, they are usually oil-free and use air-cooled technologies. These two rotating lobes always rotate in the opposite direction. When they are rotating, a fixed quantity of gas is trapped between the impeller and casing. This impeller then pushes the gas to the discharge end against the pressure that exists in the system. This is a repetitive cycle. A root blower manufacturer plays an important role in providing you with the right product.
To suit everyone’s needs, root blowers come in various configurations to suit different industrial applications:
Benyuan are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
As mentioned above the efficiency for root blowers is very important. If you use an efficient twin-lobe root blower, it can last long and can be cost-effective also. These blowers are majorly used in the water aeration, variety of industrial processes and much more.
A major advantage of use the twin lobe roots blower is that the rotor is made up of two lobes, which rotate independently. Every lobe can be driven by an external power source, this allows to rotate at different speeds, air can also be efficiently pumped.
The major advantage of the three-lobe roots blower is that it helps in reducing noise and pressure pulsation, through it six-time per revolution. This also has a unique design which reduces the of reverse flow pressure variation period. This results in less noise and turbulence, allowing the motor to have a longer lifespan.
This blower delivers the most performance by packaging a single stage centrifugal blower with advanced energy management systems. The high-speed turbo blower rely on the aerodynamic air-foil bearings.
The present day industrial blowers go back to the industrial revolution, they have been around since so long. Earlier they were used as an air pump for internal combustion engines. To understand better, the most simple design included a shaft, motor and impeller blades.
The most important things to consider while choosing the right root blower manufacturer is the experience and expertise of the field. While choosing the manufacturer always look at the experience, record, services and the high-quality blowers. The deep understanding is this field helps the customer to learn from the experts.
By understanding your requirement and then looking for the right root blower will help you learn about its efficiency. Investing in a high-quality root blower is important and this will help in improving productivity and becomes cost-effective also, if taken care properly, get in touch to explore how we can help you.
