{"product_id":"40mm-blow-off-valve-with-dual-spring-system","title":"40mm Blow Off Valve with Dual Spring System","description":"When a driver abruptly closes the throttle, airflow is rapidly restricted, leading to potential flow instability and pressure fluctuations. This surge condition can eventually cause thrust bearing failure due to the extreme loads involved. The BOV effectively mitigates this by utilizing a combination of manifold pressure signal and spring force to detect throttle closure.\n\nUpon detecting a rapid throttle closure, the BOV promptly vents excess boost pressure in the intake tract to the atmosphere. This action rapidly relieves pressure, thereby preventing surge and protecting the turbocharger. This particular Type-RS model boasts 8 discharge ports, designed to draw in surrounding air and emit a distinctive discharge sound. The 40mm hard-anodized valve ensures increased airflow, while the dual spring system promotes quicker response and supports high boost pressures, holding up to 30 PSI.\n\nThis product is explicitly intended for closed-course race or competition use only and is not legal for street use.
