The HKS's Racing SQV universal assy is the original 3-chamber structure that ensures the stable operation of the blow-off valve regardless of the amount of pressure. It has a large 51mm valve that can perform with great high power and large displacement engines. Adjustable pre-load allows a broad range of applications. Typical blow-off valves require spring load settings for each vehicle specification. If the spring load setting is too low, the boost pressure may be relieved under a high boost, and the desired boost setting may not be reached. If the spring load setting is too strong, the valve may not open at a low boost. Also, the HKS RACING SQV uses a relief-less type; therefore, it delivers stable operation at all boost levels. Durability tests of over 1 million operations minimize the chances of valve stick and achieve high durability. Installation flange is included. The flange must be welded to a pipe. A piping hose is not included. The size of the flange is different from the one for the existing SSQV.
