HKS SSQV2 Dump Valve

Blow-Off & Bypass Valves have one goal, prevent compressor surge. Compressor surge occurs when the throttle plate of a turbocharged engine closes and the pressurized air is forced back into the turbocharger?s compressor housing causing the turbo to slow down. Compressor surge not only decreases the spool of a turbo but can also damage its centre cartridge. HKS Blow-Off and Bypass Valves prevent compressor surge by venting the excess pressure when a throttle plate closes, thus improving spool-up & longevity.
