Overview
HEMI Magnuson Boost Control System – SmoothBoost Active Bypass Valve
Take control of your supercharged HEMI’s performance with the SmoothBoost Boost Control System, engineered for vehicles equipped with the Magnuson 2650 supercharger. Replacing the factory vacuum bypass valve with an electronic actuator, this system brings cleaner boost curves, sharper throttle response, and better driveability — whether you’re on the street or on the strip.
This boost control system operates smoothly using a 0–5 V signal, eliminating boost spikes, lag, and idle issues tied to vacuum operation. Benefits include:
- Linear throttle-to-boost response
-
Boost curve fine tuning — no pulley swaps needed
-
Built-in boost scramble and kill features for racers
-
Smart, bolt-on install with full wiring harness and hardware included
Crafted for seamless integration with stock or modified HEMI engines, this kit maintains OEM-level fitment. Backed by SmoothBoost’s US-based technical support, it’s the ideal precision upgrade for any Magnuson-equipped HEMI performance vehicle.
