Founded in 2018, SmoothBoost has established itself as a leader in the supercharged community, offering advanced supercharger boost control technology.

Our vision stemmed from years of experience in tuning, engine building, and all types of 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 innovative 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 expansive 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 right here in Virginia, USA using our in house state-of-the-art CNC equipment. While it’s nearly impossible to manufacture every component in our product we we source the best components available in each area to provide a product that will perform reliably for many years and miles.
