Prevents idling problems that tend to occur with blow-off

The floating valve mechanism allows the valve to react quickly because there is no need to apply unnecessary preload to the spring.

Quick response even at low supercharging

The floating valve mechanism prevents unnecessary opening and closing of the valve.

Uses a floating valve structure

By adopting a floating valve structure in which the diaphragm and valve operate independently, it is possible to achieve a valve response that exceeds that of the conventional model and a stable blow-off effect in the entire supercharging range.

Uses a new rotation-adjustable top cover

The 360 ​​° adjustable top cover eliminates the need to disassemble the top cover by changing the orientation of the hose union, greatly improving workability compared to the previous model.

Preload adjustment with fidget spinner

The easy-to-rotate fidget spinner makes it possible to adjust the preload within a range of about 5 rotations without the need for tools.

Operation of blow-off valve FV

【When the accelerator is on】

The dual valve spring, boost pressure from the surge tank, and support spring strongly press the valve to prevent relief during high supercharging.

【When the accelerator is off】

The surge tank pressure becomes the maximum negative pressure, the diaphragm and dual spring are pulled up, and the valve is released. The valve pressed only by the support spring is pushed up by the residual pressure in the pipe, and the residual pressure is released instantly.

【When the accelerator is off (after release)】

Even if the pressure inside the surge tank remains negative and the diaphragm is pulled up, the support spring closes the valve quickly when the residual pressure is released to prepare for the next accelerator ON. This will launch the boost quickly.
