LS Whipple Boost Control System – SmoothBoost Active Bypass
Gain total control over your Whipple‑2.9‑charged GM LS engine with the SmoothBoost LS Whipple Boost Control System, replacing the factory vacuum bypass valve with a precision electronic setup. This solution brings smoother throttle response, improved drivability, and easier tuning—even on high-boost builds.
The system uses a reliable 0–5 V signal for valve control instead of relying on manifold vacuum. Benefits include:
- Linear throttle-to-boost performance for better on-road feel
-
Elimination of vacuum-related boost spikes, overshoot, and lag
-
Ability to reduce boost up to 80% without pulley swaps
-
Boost scramble & kill option for race-day setups
Designed to seamlessly integrate with Whipple 2.9 systems on LS cars and trucks, this kit installs easily and works with stock or upgraded setups. Includes SmoothBoost controller, wiring harness, and mounting hardware. Backed by expert US-based support, this is the smart upgrade your LS ride needs.
