High-Quality Dual Velocity Stack / Air Trumpet for Weber DCOE Carburetors

Bring both classic performance aesthetics and optimized airflow to your custom engine build. This dual velocity stack is meticulously designed for classic Weber DCOE setups (perfectly optimized for 45 DCOE profiles with its 45mm internal references). It features a smooth, progressive bellmouth flare to maximize air velocity and reduce turbulence into the intake barrels.

Whether you are mock-printing for a real-world restomod project, building a high-end custom engine display, or creating a highly detailed large-scale RC/diecast model, this mesh is clean and ready to go.

• Total Height: 90.00 mm
• Base Length: 175.58 mm
• Base Width: 85.48 mm
• Mounting Type: Integrated dual-flange base with standard DCOE bolt-hole spacing and central clearance slot.

While the model does not include pre-baked supports, it has been designed from the ground up with clean geometry for clean slicing.

• Orientation: Print base-down for maximum stability. Minimal supports may be required under the outer edges of the upper flare depending on your printer's bridging capabilities.
• Real-World Automotive Use: If printing for functional testing or temporary engine bay fitment, do not use PLA. Use high-temperature, fuel-resistant filaments such as ASA, ABS, or Nylon (PA) to withstand engine bay heat and ambient fuel vapors.
• Scale Modeling: For scale miniatures, this model scales down beautifully on resin (SLA) printers.
