Check this Differences, Between Roots Blowers and Screw Blowers!?
Are you interested in learning about the differences between Roots blowers and screw blowers? If so, you’ve come to the right place. In this article, we’ll dive into the intricacies of these two types of superchargers, and explain why one might be a better fit for your engine than the other.
First, let’s talk about what these superchargers actually do. Both Roots and screw blowers are designed to increase the amount of air that’s flowing into your engine, which in turn can lead to more power. However, they go about it in slightly different ways.
A Roots blower uses a set of rotating lobes to pull air into the engine. These lobes touch each other as they spin, which means that the Roots blower builds up a lot of heat in the process. Additionally, because of the way the lobes are shaped, Roots blowers tend to be less efficient than their screw counterparts.
Screw blowers, on the other hand, use a pair of helical rotors to compress air. These rotors don’t touch each other, which means that screw blowers don’t generate as much heat as Roots blowers. They’re also more efficient, which can result in more power.
But if screw blowers are so great, why doesn’t everyone use them? Well, there are a few reasons. First of all, screw blowers tend to be more expensive than Roots blowers. Additionally, because they spin at such high speeds, they can be more difficult to tune properly.
Another thing to consider is the fuel system you’ll be using with your supercharger. In the video, the presenter mentions that they use a mechanical injection system on their cars, which means that there’s no computer controlling the fuel flow. Instead, fuel is added or subtracted based on the position of the throttle. This type of system works well with Roots blowers, but can be more difficult to tune with screw blowers.
So which type of blower is right for you? That depends on a variety of factors, including your budget, the type of engine you have, and your goals for the car. If you’re looking for the most power possible, a screw blower might be the way to go. However, if you’re on a tighter budget and/or have a less powerful engine, a Roots blower could be a better fit.
In conclusion, both Roots and screw blowers have their advantages and disadvantages. If you’re considering adding a supercharger to your engine, it’s important to do your research and choose the type of blower that’s best for your specific situation.
