The Mercedes A35 Eventuri Turbo Tube has been developed to provide the turbo with a less restrictive flow path as compared to the stock tube. We have managed to increase the internal volume as well as eliminating the ridged flexible section at the airbox side. By using a completely solid tube all the way from the intake to the turbo, the flow path is smoother and therefore airflow can remain more laminar. To account for engine movement, our A35 intake has a “floating” tube, which can move within the airbox. The shape of the carbon tube at the turbo end has been optimised using CFD to minimise turbulence. The connection to the turbo is achieved with an innovative silicon coupler that features an internal thermal separator between the carbon tube and the metal turbo housing. The multiple breather connectors at the back of the tube are taken care of with a CNC machined block which also provides a smooth internal surface for airflow within the tube.
