BoostPRO is proud to introduce our newest generation of "Push-Type" blow off valves, the FV Series, capable of supporting up to 430HP!   This new "Floating Valve" design is an engineering breakthrough that produces quicker valve response, increased valve travel and improved resistance to premature valve lift/boost leak!  

The unique floating valve design incorporates a durable , adjustable, dual-spring system and heat-resistant silicone diaphragm.  This allows the springs and diaphragm to better control the valve during boost.  By keeping one spring over and another under the diaphragm, the spring pre-load is less dependent on idle in light boost situations, making this the best performing 40mm blow off valve you can buy.

 Another beneficial feature is our adjustable, sliding top hat, allowing you to adjust the hose fitting location to suit your vehicle without completely disassembling the valve.
