With tens of thousands of kits sold, SmoothBoost has established itself as a leader in the supercharger community, offering advanced supercharger boost control technology for all superchargers...

Founded in 2018, our vision stemmed from years of experience in tuning, engine building, and automotive fabrication. Frustrated by the limitations of traditional vacuum bypass valves, we set out to revolutionize aftermarket supercharger performance by providing precise bypass valve control. By referencing throttle position instead of manifold pressure, this innovating breakthrough ensures smooth, factory like linear power delivery while maintaining the instant, neck-snapping acceleration that superchargers are famous for.

With features like a boost control knob, boost cut failsafe, and boost scramble included right out of the box, SmoothBoost also offers expansion capabilities previously exclusive to turbocharging. Advanced options such as Boost by Gear, RPM, and Time can be accessed using aftermarket ECUs or other PWM control systems. ​

SmoothBoost optimizes bypass positioning while cruising, enhancing overall fuel efficiency and keeping your blower cool and ready for instant power on demand.

​A significant portion of our kits is expertly crafted in-house using state-of-the-art CNC equipment. While it’s nearly impossible to manufacture every component, we partner with industry leaders in each area to provide a product that performs reliably for many years and miles. ​

This is the next evolution in supercharger technology.
