1. GReddy (11501665) Blow-Off Valve
Feature
GReddy Type FV Universal BOV - Floating DesignDescription
Greddy has updated their popular blow off valve for late 2013 with a new Type FV series universal BOV. The GReddy BOV FV is a new generation of blow off valve. The unique "Floating Valve" design incorporates a revised adjustable dual spring system, while maintaining the advantages of the previous model's push valve structure and silicone diaphragm control. The improved design makes spring preload setting less dependent on the idle, while providing better response, increased valve travel, more air-flow and added resistance to premature valve lift under all conditions. Also maintained is a slimmer CNC outlet with discharge ports to draws surrounding air to amplify the blow-off sound, however this can be replaced with optional re-circulation adapters in various sizes. The BOV FV adopts the same mounting and outlet size and position as previous GReddy RZ and RS models, so retro-fitting onto existing applications is possible. All GReddy BOVs are compatible with standard GReddy Blow-off Valve flanges (flange NOT included).2. Adjustable and Universal Blow off Valve, Floating Valve Design, 12 Month Manufacturer Warranty
Feature
FLOATING VALVE DESIGN: Paisley Industries blow off valve features a floating valve design with opposing springs which allows for improved control, response and idle. Turbo blow off valve top hat design allows for rotating of the vacuum nipple without disassembly of the unit.WILL NOT LEAK: Paisley Industries blow off valve features a dual stage pull-type relief valve. Unlike typical push type blow-off valves, will not leak under any level of boost.
TYPE FV: Size 40, 100-420hp range, BOV gasket, nuts & bolts makes this a universal and effective blow off valve solution for all turbocharged / supercharged cars.
MAX PERFORMANCE, HIGH LUSTER LOOK: Incorporates both a small primary valve for ultra quick activation and a larger secondary valve for additional discharge capacity. Constructed with high quality billet aluminum ensuring long-term durability and a high luster look.
INNOVATIVE DESIGN: Innovative design makes spring preload settings less dependent on the idle providing better response Unique triple fin design produces "Super Sound," Triple Fins are set at the center of the funnel producing an adynamic and aggressive sound.

3. Type-FV 4'' Adjustable Blow Off Valve (BOV) with 2 Bolts Aluminum Body Up To 30 PSI (Blue)
Feature
2 Bolt Mounting DesignHolds Up to 30 PSI Boost Pressure
Billet Aluminum Body
Valve is Independant from Diaphragm. Making Less Adjustments Needed to stay shut during Idle
Dual Spring System Promoted Response and Allows for High Boost Pressures
Description
The Blow-Off valve (BOV) is a pressure relief device on the intake tract to prevent the turbos compressor from going into surge. When the throttle is closed rapidly, the airflow is quickly reduced, causing flow instability and pressure fluctuations. Surge can eventually lead to thrust bearing failure due to the high loads associated with it. Blow-Off valves use a combination of manifold pressure signal and spring force to detect when the throttle is closed. When the throttle is closed rapidly, the BOV vents boost in the intake tract to atmosphere to relieve the pressure, helping to eliminate surge.Package Included:
