GReddy BLOW OFF VALVE FV VEHICLE SPECIFIC KIT
GReddy BLOW OFF VALVE FV has adapted Floating Valve structure which does not pull up when the Surge Tank is 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. The attachment flange and the air outlet position is the same as GReddy BLOW OFF VALVE TYPE-RS、RZ. It is possible to replace from the previous model. KIT for each vehicle type includes parts for fitting with the normal car. By a car model, there are simplex AIR OPEN, simplex AIR RETURN type and the selectable type.

Specification
Prevent idling disorder to be caused by blowoff
For the floating valve structure, the valve moves quickly without unnecessary preload of the spring.
Quick response at low boost
Prevent the loss time of opening and shutting the valve by the floating valve structure.
Adopted the new developed floating valve structure.
This product adopts floating valve design that diaphragm and valve are moving independently, and it insures quicker valve response than previous product and stable blow-off action through all pressure area.Adopted an new slide type top hat
BLOW OFF VALVE FV operation
[Throttle ON]Dual valve spring, the conbination of the new adjustable valve spring system and the intake manihold pressure provide great control to keep the valve shut even in high boost situations.
[Throttle Off] Valve preload is removed when surge tank pressure becomes vacuum and diaphragm and dual spring is pulled. The lower spring rate allows the charge-pipe boost pressure to easily open the valve faster, blow-offs quicker. [Throttle OFF (after blow off)]Even the intake manifold pressure is vacuum and diaphragm is pulled up, once remained pressure is expelled, the new lower spring closes the valve in preparation for throttle ON to be re-opened and boost to resume.
