response even at low boost

The floating valve mechanism prevents the valve from opening and closing unnecessarily.

Floating valve structure

By adopting a floating valve structure in which the diaphragm and valve operate independently, we have achieved valve response that exceeds that of previous models and a stable blow-off effect across the entire supercharging range.

New rotating adjustable top cover

The top cover can now be adjusted 360°, eliminating the need to disassemble the top cover to change the direction of the hose union, greatly improving workability over the previous model.

Preload adjustment with hand spinner

The easy-to-turn hand spinner allows preload adjustment over a range of approximately 5 turns without the need for tools.
