Understanding Superchargers: Roots vs. Centrifugal

Before you jump into the world of supercharging, let's break down the two main types you'll encounter: Roots and Centrifugal superchargers. These systems work differently, and understanding the differences is key to making the right choice for your 1970 Dodge Challenger RT.

  • Roots Superchargers: These are the classic, old-school superchargers. They sit on top of the engine and are known for their instant torque and distinctive whine. Roots superchargers deliver boost throughout the entire RPM range, making for impressive off-the-line acceleration. They're often preferred for their aggressive look and feel, adding a touch of vintage cool to your muscle car. However, they can be less efficient than centrifugal superchargers at higher RPMs and tend to generate more heat.
  • Centrifugal Superchargers: Think of these as a turbocharger driven by the engine's belt. They resemble a turbocharger in appearance and are typically more efficient than Roots superchargers, especially at higher RPMs. Centrifugal superchargers provide a more linear power curve, meaning the power builds gradually as the RPMs increase. This can make the car more manageable on the street and is often preferred for track use. They generally produce less heat and can be more cost-effective. The downside is that they may have a slight lag compared to Roots superchargers, as boost builds with engine speed.

Choosing the right type depends on your goals. If you want instant torque and that iconic supercharger whine, a Roots system is a great choice. If you're looking for efficiency, a smooth power curve, and a more modern feel, a centrifugal supercharger might be a better fit for your 1970 Dodge Challenger RT. Consider your driving style, budget, and desired power output when making your decision. Both options offer a significant power increase, so the choice ultimately comes down to personal preference and how you intend to use your car.
