PowerCarb4 15S-3 - 6.5mm Venturi Insert

With the PowerCarb4 15S-3 venturi inserts, the engine characteristics can be precisely adapted to track layout, grip level and driving style.

They have a significant influence on the airflow velocity of the air-fuel mixture inside the carburettor and therefore determine how directly the engine responds, how strongly it pulls from low RPM and how much power is available at high RPM.

Smaller diameters increase the airflow velocity. The engine responds more spontaneously, delivers stronger punch from low RPM and remains more controllable when accelerating out of tight corners and on low-grip surfaces. At the same time, fuel consumption is reduced.

Larger diameters allow a higher air throughput. The engine achieves more top-end power at high RPM and offers clear advantages on high-speed tracks or in high-grip conditions.

The venturi inserts are available in the following diameters:
6.5 mm - 7.0 mm - 7.5 mm - 8.5 mm - 9.0 mm
