Supercharged Vacuum-Powered Truck Instructions (ONLY)

LEGO® Vacuum-Powered Truck

Digital Build Instructions

Build a fully functional vacuum-powered truck featuring a high-RPM single-cylinder engine, multi-speed transmission, and working drivetrain. This build is designed for builders who want mechanical realism, interactive controls, and serious performance.

At the heart of the truck is a supercharged single-cylinder LEGO Vacuum Engine (LVE) capable of spinning 8,000+ RPM. When connected to a powerful vacuum source, the engine will idle on its own, allowing you to use the throttle lever to rev the engine before engaging the clutch and selecting a gear.

Once you’re ready, engage the clutch, shift into gear, and drive.
