Garrett Vent | Blow-Off Valves release excess boost pressure from the charge pipe when the throttle is closed, preventing damage to the turbocharger and other engine components, ensuring smooth operation and prolonging the turbo’s lifespan. Garrett Vent | Blow-Off Valves are created by the engineers that designed G-Series turbochargers and GVW Wastegates. GVB-50 is a high-flowing BOV with a 50mm valve, available in four striking color combinations: Red | Blue | Black | Silver. Select between vent to atmosphere (VTA) and recirculating (RCV) housing options. Delivering a maximum flow up to 350 CFM | .21kg/s (RCV) as a result of advanced CFD design software used to simulate, visualize, and quantify airflow before manufacturing started (GVB-50R RCV). The proprietary designed, high-temperature Nomex reinforced elastomer diaphragm ensures unmatched durability and fatigue resistance. A plated stem and bushing lower friction and improve wear resistance.
GVB Blow-Off Valves are set to 10 PSI of base pressure and offer configurable rates from 0.2 Bar | 3 PSI - 0.9 Bar | 13 PSI. Unlike the other products on the market, Garrett includes five springs enabling fine tuning of the pressure setting to optimize BOV performance, and therefore overall turbo system performance. The single vacuum port streamlines functionality. Every kit contains- all fasteners, springs, fittings, V-bands, clamps, and flanges.
