Do Centrifugal Superchargers Have Lag? (All Your Questions Answered)

Adding a supercharger to your vehicle is a great way to obtain more power from your vehicle. However, you need to understand that there are several types of superchargers and they’re all unique in one way or another. If you do not get the right one, there is a good chance that you’re going to experience issues or you may not like the performance. The centrifugal supercharger is one of the most popular. So, is it a good investment?

Do centrifugal superchargers have lag? Yes. Centrifugal superchargers are a little different. The boost is going to depend on the RPMs. For instance, you may not experience that boost until your vehicle soars past 3,000 RPMs. Therefore, there would be somewhat of a lag.

Still, centrifugal superchargers offer numerous benefits that may outweigh this con. Below, you will learn more about these superchargers, their benefits, and reasons to add them to your vehicle.

What Is A Centrifugal Supercharger?

Again there are several types of superchargers. To get the right one, you need to take your time and learn more about the different types. The centrifugal supercharger is unique. As mentioned above, this type is dependent on RPM and that is what sets it apart from the competition. Unlike the alternatives, you’re going to get the boost almost immediately.

This will not happen with a centrifugal supercharger. Instead, you’re going to receive more power once your vehicle has climbed to higher RPMs. This specific type will be more efficient when the impeller is spinning faster. Therefore, you have to be patient with the centrifugal supercharger. On average, these superchargers will begin providing a boost around 3,000 RPMs.

Do centrifugal superchargers have lag? Yes as they’re designed to lag.


Ultimately, there are several differences between centrifugal superchargers and the alternatives. It is valuable to know these differences in advance so you can determine which type of supercharger is going to be best for you. As mentioned above, the centrifugal supercharger can have more lag. One of the biggest differences is the fuel efficiency. With the alternatives, your gas mileage is going to be impacted significantly.

Centrifugal superchargers will not have a major impact on gas mileage. In return, you’ll be able to get a boost without paying for it in the future. You’ll receive more power on the top end too. Another difference is the sound. With a centrifugal model, the volume level is going to be much lower. If you like the whine of a supercharger, you’ll want to go with one of the alternatives.

Is It Really Lag?

Some will argue that this type of supercharger doesn’t actually lag. This may be true. After all, lag is commonly used to describe the amount of time it takes for the booster to kick in after you’ve hit the pedal. In this sense, you’re not actually getting lag. The centrifugal supercharger will start turning at constant RPMs from the beginning. You just won’t experience the boost until you’ve hit the correct RPMs. This is why some people argue that there is no lag.

However, it is easy to stay that there is. After all, you’re not going to experience the boost as soon as you step on the pedal.

Benefits Of Centrifugal Superchargers

Ultimately, centrifugal superchargers offer many benefits. Some of these benefits can be obtained from other superchargers but some cannot. So, what are the major benefits? You’ll find out below.

Better Power

This type of supercharger is going to provide your vehicle with additional power when the motor’s speed increases. At lower engine speeds, the boost that you receive is going to be limited. When the horsepower is higher, the boost is going to be significantly higher. Either way, all types of superchargers can provide you with a big boost and the centrifugal types aren’t any different.


Another thing to note is that centrifugal superchargers rely on centrifugal forces to compress air. This is going to make a big difference. Positive displacement types tend to have low efficiency. The centrifugal supercharger is going to be more efficient in many areas. It will offer better power consumption efficiency. It is also better in terms of heat production.

This is why the centrifugal supercharger is going to offer better gas mileage. If you want the boost without having to pay too much for it, this is the best way to go. The centrifugal supercharger will give you exactly what you’re looking for.

Heat Transfer

When it comes to the installation procedure, the centrifugal supercharger is slightly different. Instead of being mounted directly to the engine, this type will be mounted nearby. Usually, it will be placed to the side of the engine’s front. This gives it a little extra distance away from the supercharger and that can offer numerous benefits. For starters, this is going to reduce heat transfer during operation.

Twin-screw and root types will be installed in the valley of the engine and this means that they’re going to absorb the heat. With these types, the supercharger is going to be releasing hot air that will be sucked into the engine. This results in the power being reduced. Also, it increases the likelihood that you’re going to experience engine problems.

With that being said, the centrifugal supercharger is really the most efficient and safest supercharger you can add to your vehicle.

About The Other Types

The centrifugal supercharger has become one of the most popular. However, you cannot ignore the other two types. They are great in their own right. Below, you will learn more about these two types and their basic functionality.


The root supercharger is the oldest of the bunch. This type of unit is going to rely on large amounts of air. It will provide you with quick bursts of energy and this is why it is so popular for racing. When compared to the alternatives, the root supercharger is the cheapest of the bunch. Root superchargers are large and they need to be mounted on top of your engine.


Next, you have the twin-screw supercharger. These units are going to draw air in through lobes. That air will be trapped inside of the rotor housing. Unfortunately, twin-screw superchargers are not for everyone. First and foremost, they have been outlawed in some states. Therefore, you’ll need to get with your state laws before moving forward. At the same time, they’re more expensive. Finally, twin-screw superchargers are noisier. They’re louder and this is why some people do not prefer them.

Maintaining Your Centrifugal Supercharged Car

Once you’ve added a supercharger to your vehicle, you’ll need to take additional steps to keep that vehicle in good condition. This is going to be more difficult than you might imagine. Below, you’ll discover things that you need to do to avoid problems.

Keep An Eye On Oil Levels

Since you’ve added a supercharger to your vehicle, you’ll need to pay close attention to the vehicle’s oil levels. All superchargers are going to put more pressure on the vehicle’s engine. If the engine doesn’t receive enough lubrication, it is going to malfunction. It will be damaged severely and you’ll be looking at an expensive repair bill. You should check the oil levels frequently to avoid such problems.

Check The Filters

For the vehicle to perform at the top of its game, you need to keep an eye on the filters. Clogged filters are going to reduce the vehicle’s performance and put more strain on the engine. This can deliver unsatisfying results while also damaging the engine. If the filters are dirty or clogged, you’ll want to replace them immediately. It is wise to replace the air filter every time you change the oil. Keep the filters clean and you’ll experience a better boost and fewer problems.

Inspect The Clutch

Centrifugal superchargers are going to place more stress on the vehicle. This will cause the vehicle to be driven harder. Therefore, you have to be worried about the clutch. It takes a lot of abuse and you’re going to be putting more on it. It is best to have the clutch inspected at least once a month to avoid serious problems.

Other Things To Do

There are several other things you’ll need to do to keep your vehicle in tiptop shape. After you’ve installed the centrifugal supercharger, you’ll want to make sure that the tires are in perfect alignment. Take your vehicle to the shop and get the tires aligned. You should always use the best gasoline. Lower quality fuel grades will result in more gunk being added to the engine. Make the upgrade and spend more on fuel to avoid such problems.

Finally, you should make enhancements to the vehicle’s cooling system. Superchargers can make the vehicle hotter. Therefore, you need to take steps to keep the temperatures to a minimum. Upgrading the cooling system can help.

Centrifugal Supercharger Installation

As you’ve already figured out, the centrifugal supercharger is one of the best. However, it is not a flawless solution. It comes with many problems that you need to avoid. One of the most notable is the installation procedure. If you do not install the unit correctly, you’re going to experience a lot of problems. Of course, the biggest flaw here is the fact that the centrifugal supercharger is the most difficult to install. The installation procedure will be more complicated and this is why you should let a professional do it.

This will increase the price to some degree but it’ll be well worth it in the long run. You do not want an incorrect installation as that will lead to big problems in the future. Be sure to spend more and hire a professional to handle it for you. This will allow you to enjoy your supercharger to the fullest and avoid the problems that could come your way in the future.


The centrifugal supercharger is one of the best on the market. It offers benefits that aren’t available with the root or twin-screw supercharger. Still, many people have questions. Do centrifugal superchargers have lag? While you could spin the answer to say no, they do. You’re not going to get the boost immediately. Nevertheless, these superchargers offer numerous benefits that make them worth it. If you’re not worried about a small amount of lag, you’ll want to consider adding one of these superchargers to your vehicle.
