SUPER SQV

HKS Super SQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure. The Super SQV will support new generations of turbocharged vehicles.

1.High Quality Aluminum Die-Cast Body

Silver-coated aluminum die-cast body. Combines the ultimate in looks and durability in the engine compartment.

2.High Stiffness Metal Die-Cast Valve

Secondary valve main portion is made of die cast metal. Reliable operation with beautiful looking.

3.Triple Fin design produces “Super Sound”

Triple Fins set at the center of the funnel produces a dynamic and aggressive sound. An optional special Round Fin can be purchased separately for sound tuning.

1.Pull-Type Relief Valve Operation

The Pull-Type valve operation offers more precise relief of excess boost and is compatible for a wider range of boost pressure compared to typical push-type blow off valves.

2.Primary Valve (Small)

Lift off the throttle, and the primary valve instantly opens, quickly discharging initial excess boost pressure.

3.Secondary Valve (Large)

This valve combined with the Primary Valve from the sequential dual valve structure. Optimal blow-off operation from how to high boost ranges without leaking.

At low boost ranges the Primary Valve opens, and at high boost ranges the Secondary Valve also opens, resulting in linear response and optimal blow-off operation at all boost levels.

    Accelerator ON, Valves Closed

    As pressure rises in chamber C, pressure is applied to both the Primary and Secondary valves. The higher the boost pressure, the more pressure is applied to the valves, preventing leaks.

  • Accelerator OFF
    Primary Valve Opens

    Accelerator OFF, Primary Valve Opens

    Throttle lift creates a pressure difference between chambers A & B, opening the primary valve bypassing the secondary valve. this creates the initial discharge.

  • Accelerator OFF
    Secondary Valve Opens

    accelerator off, secondary valve opens

    When pressure difference in chambers A & B reach a maximum, the Primary Valve pulls the Secondary Valve open, creating a secondary discharge.

Pull-Type blow off valves will work for any turbocharged vehicle, from stock to highly tuned.

Typical push-type blow off valves require spring load settings for each vehicle specification. If the spring load setting is too low, the valve may leak under high boost and the desired boost setting may not be reach. If the spring load setting is too strong, it may not open at low boost. The Super SQV will operate under any boost pressure setting without leaking.

  • HKS changed the intercooler charge pipe for the outlet side to the casting aluminum-made pipe compared to the resin-made stock ones. This prevents expansion or damage to the pipe due to age deterioration.
  • Coordinate your engine bay stylishly with the presence of the SQV IV at the front of the engine.
  • Using the provided suction return hose meets the automobile inspection in Japan.
  • The kit allows using the combination use of the stock air bypass valve without any cancellation when installing the SQV IV.
