Due to its particular shape reduces air turbulence during the intake phase, improving airflow and reduces the response time of the engine, in particular, there has violent opening of the gas.
Its shape and length have been designed by our design department to be connected to the motor at different speeds, increasing the strength of aspiration and improving the filling at low engine speeds.
The stacks have been developed for specific uses: a BLUE series for the throttle body of the Tmax 500, a BLACK series for the throttle body of the Tmax 530 and a GOLD series which is designed to be mounted on our enlarged 36, 38 and 40mm throttle bodies.
The test bench showed, compared with a gain series conducted from 2 to 3 hp.
Of course, like any changes made to the engine needs a tune-up injection to take advantage of the change.
The trumpets are made of aluminum and machined on CNC machines.
