GReddy BLOW OFF VALVE FV-II has adapted the Floating Valve structure which does not open up when the Surge Tank has negative pressure. For no strong initial load, both quick response under low boost and prevention of the relief under high pressure are together. This is a new generation blow-off valve.

Features

• Gunmetal/Blue, adjustable detent rotary knob, floating valve, revised funnel outlet

• Floating Valve design with opposing springs, allows for improved control, response, and idle.

• The new top hat design allows for rotating the vacuum nipple without disassembly of the unit.

• 80-480hp range
  
  The GReddy FV II adopts the same mounting and outlet size and position as previous GReddy RS and RZ models, so retro-fitting to existing applications is possible.
