Blitz Blow Off Valve VD Toyota Celica 89-94
The Blow-off valve is essential to all turbocharged vehicles. The purpose of the BLITZ Blow-off Valve VD is to relieve compressor surge without reducing compressor speed. It controls boost pressure that is built up by the turbo and vents it into the atmosphere when the car is not under load (in between shifts). This prevents pressure from backing up into the compressor housing, causing the turbo impeller blade to rapidly stop or even worse, to spin backwards (compressor surge or backspin). Doing so can be potentially destructive to the turbine wheel and shaft. Repeated stress over time can cause eminent damage to the turbo charger and eventually lead to turbo failure. A blowoff valve is actuated by pressure changes only, ensuring quick valve responses and complete closures at idle. The BLITZ blow-off valve not only improves performance and response, but also increases the life of the turbocharger.
About Manufacturer: Blitz
BLITZ began in the late 1970s as a circuit racing team and eventually developed into a high performance tuning shop. In 1980 BLITZ Co., LTD. was established in Tokyo, Japan. The concept was to produce high performance products without sacrificing the capability if being daily driven, commuter cars. A key to BLITZs success was from the extensive race experience and also the use of German made KKK turbos, currently owned by the Borg Warner Corp. With the integration of KKK components, BLITZ had been able to produce high performance products for race and street purposes.
