The SmoothBoost Hellcat Controller is an essential standalone device designed to operate the factory Hellcat bypass valve in supercharger swap applications. This controller is crucial when integrating a Hellcat-based supercharger into a system where the Powertrain Control Module (PCM) cannot directly manage the bypass valve.

SmoothBoost is the original Hellcat Bypass Controller. We have refined our product over the years to have the best quality and workmanship. Proudly built the USA with no Chinese parts. We use the best electronics available to us give you longevity you can rely on. Refined to the highest craftsmanship standards and technological excellence.

Key Features:

  • Precision Craftsmanship Bar None: Constructed from high-quality billet aluminum, this controller embodies superior craftsmanship and durability. 

  • Standalone Operation: Compatible with any engine management system, whether factory drive-by-wire or aftermarket drive-by-cable ECUs. The SmoothBoost Controller provides seamless control over the bypass valve regardless of your setup.

  • Included Boost Knob Adjustable Boost Levels: Adjust boost levels to enhance driveability, accommodate varying fuel quality or lower stress on the engine and drivetrain. This controller allows you to dial down a 1000+ horsepower engine to a more manageable 500 horsepower with a simple adjustment. Note: The boost knob is optional to use and can be left off if you have no reason to lower the boost.

  • Versatile Integration: Ideal for Hellcat supercharger swaps, this device can also be custom-installed and tuned to work with factory Hellcat-based vehicles, offering flexibility and performance enhancement by having a way to control boost levels on the fly as well as boost ramps when using an outside source such as the PWM(-) output of a nitrous controller

  • Aftermarket ECU Integration: Expand your boost control capabilities with the SB-DCA module, allowing the controller to be managed directly from an aftermarket ECU. This integration offers enhanced tuning flexibility and advanced control over boost levels.

  • User-Friendly Adjustment: Provides precise control over your vehicle’s boost, allowing for fine-tuning to match specific driving conditions and performance needs.

  • Plug-and-Play Throttle Signal Connector: Includes a convenient plug-and-play throttle signal connector for straightforward installation. This feature simplifies the integration process, reducing setup time and complexity.

Compatibility:

  • Designed specifically for applications involving Hellcat-based superchargers where the factory PCM does not control the bypass valve. Suitable for both new installations and existing setups with proper tuning and installation.

Note: Professional installation and tuning are recommended to ensure optimal performance and integration. Consult with a qualified technician to achieve the best results
