This is because a supercharger is driven by the engine's crankshaft and does not rely on exhaust gasses like a turbocharger. This means that power delivery is more predictable and can be more easily controlled with throttle inputs.
Superchargers are also generally easier to install and maintain than turbochargers. They don't require complex exhaust and intake systems and can be easily bolted onto the engine. Additionally, they do not generate as much heat as turbochargers, which means they are less likely to cause heat-related problems such as engine knocking.
A supercharger can provide reliable and consistent power gains for an Acura RSX, making it a great option for owners who want to increase their car's performance without sacrificing drivability. However, it's important to note that superchargers can be a relatively expensive modification and may require additional upgrades to your engine and supporting systems to ensure reliability doesn’t go out the window!

Upgrading the transmission is an important consideration when it comes to improving the overall performance of your Acura RSX. A transmission with a few good upgrades can help handle more power and improve shifting, leading to a more engaging and enjoyable driving experience. Upgrading your RSX’s transmission can also help with acceleration as you are able to shift through the gears in a more direct, precise shift which means faster shifting overall!
In the next section, we will discuss some of the most popular transmission upgrades for the Acura RSX, including short shifters, lightweight flywheels, and upgraded clutches. By upgrading the transmission in your DC5, you can transform your RSX into a more capable and engaging sports car that is able to handle whatever you throw at it without breaking a sweat!
Upgrading the clutch is an essential modification for any Acura RSX that is being modified for performance driving. The stock clutch is designed to handle the power output of the car's original engine and is not well-suited to handle the additional power produced after adding a few modifications. Upgraded clutches can provide better engagement, a higher torque capacity, and increased durability over the stock clutch, which is prone to slippage and premature failure when driven hard.
Aftermarket clutches for the RSX are available in a variety of materials and designs, such as organic, ceramic, and multi-plate options. Each material has its unique advantages and disadvantages, and the choice of clutch material depends on the specific requirements of the driver.
In general, ceramic clutches are better suited to high-performance applications as they can handle higher temperatures and provide improved engagement over organic clutches. Multi-plate clutches are also an excellent choice for high-performance driving, as they offer a higher torque capacity and more consistent performance.
Overall, upgrading the clutch is an essential modification for any Acura RSX that has been modified for performance driving. An aftermarket clutch can provide better performance, greater durability, and a more engaging driving experience whether you are on the street or at the track.

Installing an aftermarket flywheel is a popular upgrade for the Acura RSX, as it can provide a number of benefits for those who want to improve the overall performance and driving experience whenever they hop behind the wheel.
One of the biggest benefits of an aftermarket flywheel is a reduction in rotational mass. The flywheel is responsible for transferring power from the engine to the transmission, and the lighter the flywheel, the less energy is required to spin it. This means that the engine can rev up more quickly, resulting in faster acceleration and a more engaging experience for the driver..
Another benefit of aftermarket flywheels is that they can help improve engine braking. For example, when you release the accelerator pedal, the flywheel slows down the engine, which can cause the car to slow down as well. A lighter flywheel can make this process more efficient, allowing the driver to slow down more quickly without having to rely as much on the brakes. An increase in engine braking may be notable for those that are looking to track their cars, but may be a hindrance to Acura RSX drivers that daily drive their vehicles.
In summary, an aftermarket flywheel can provide a range of benefits for Acura RSX owners looking to enhance the performance of their vehicles. From improved acceleration and throttle response to better engine braking and a smoother ride, there are many reasons to consider upgrading to an aftermarket flywheel. When it comes time to choose a new flywheel, be sure to do research on what will work best with how you plan to drive your RSX, as a flywheel that is too lightweight may have a significant impact on drivability for your street car!

Short shifters are a popular upgrade among all sorts of car enthusiasts and can provide a number of benefits for your Acura RSX. With a shorter throw between gears, you can shift more quickly and with greater precision, allowing you to maintain better control of your Acura RSX at higher speeds. A shortened shifter can also make shifting feel smoother and more precise, giving you greater confidence and a more engaging driving experience.
Beyond the practical benefits, short shifters can also add a bit of bling to the interior of your car, with many aftermarket options available in a variety of colors and finishes. And because they are relatively inexpensive and easy to install, a short shifter is often one of the first modifications that many RSX owners do to their cars.
When combined with other transmission upgrades, such as an aftermarket clutch and lightened flywheel, a short shifter can help to transform your RSX into a truly high-performance machine, capable of delivering an unparalleled driving experience both on and off the track.
