2024 hellcat whine compilation filmed by #moparbro fred_eazy25

The Hellcat supercharger whine is one of the most iconic and distinctive sounds in the performance car world. It comes from the massive 2.4L IHI supercharger (or upgraded units like the 3.0L Whipple) forcing air into the engine at high pressures. The whine is amplified by the supercharger's rotors spinning at incredibly high speeds—up to 14,600 RPM in the stock configuration.

How to Enhance the Hellcat Whine:
If you're looking to make the supercharger whine even louder, here are some effective ways to achieve it:

Aftermarket Intake Systems: A high-flow cold air intake can increase the volume of the whine by allowing more air into the supercharger.

Pulley Upgrades: A smaller supercharger pulley increases rotor speed, which amplifies the sound while also boosting power.

Throttle Body Upgrades: Installing a larger or ported throttle body improves airflow, indirectly enhancing the supercharger's auditory presence.

Removing Hood Insulation: The stock hood insulation dampens some of the noise. Removing it allows more of the whine to escape into the cabin and outside.

Catless Mid-Pipes or Straight Pipes: Reducing exhaust restriction can make both the supercharger whine and exhaust note louder.

Upgraded Supercharger: Swapping to a Whipple 3.0L or Kenne Bell unit can significantly increase the whine due to their design and airflow capacity.

Sound Resonators: Some enthusiasts have experimented with resonators tuned specifically to amplify the supercharger whine.


Ah, the Hellcat supercharger whine—a symphony of mechanical might! 🎶 It's not just a sound; it's a declaration of power. Hearing that high-pitched scream as the throttle opens and the boost builds is enough to give any car enthusiast goosebumps. Combine it with the deep rumble of the HEMI V8, and it's the perfect blend of aggression and refinement.

Here’s a fun fact: The Hellcat’s 2.4L IHI supercharger can pump up to 30,000 liters of air per minute at maximum output! To put that in perspective, that's enough air to fill a medium-sized room in less than a second.

Also, at full throttle, the supercharger generates 11.6 psi of boost, effectively doubling the atmospheric pressure and cramming in twice the amount of oxygen for that monstrous 707+ horsepower. The sound? That’s just the cherry on top, created by the supercharger rotors slicing through the air at 14,600 RPM. 🔥

It’s no wonder that whine is music to the ears of any Mopar enthusiast!
