Inlet flange 38 mm for ALV40 Gen-V Anti-Lag valveTurbosmart ALV40 Gen-V Anti-Lag valve inlet flange made of AluminiumAluminium Inlet adapter 38 mm to connect the Turbosmart anti-lag GEN 5 valve with a boost pipeThis inlet flange is required to connect the inlet of the Turbosmart ALV40 Anti Lag Wastegate to a boost pressure pipe.Tech facts about Anti Lag: The wastegate requires the excess charge air (when the throttle body is closed) to be directed into the manifold via the ALV40 Anti-Lag valve. There it is then ignited by ECU programmed fuel injection. Thus the exhaust gas pressure is maintained and the turbine wheel in the turbocharger is kept at speed, so there is no turbo lag during and after a gear change. This technology comes from the WRC and has been used for 40 years.A similar principle is used for the deactivated drive in coast, in this mode fuel injection continues and the ignition is programmed to "late". This means that the mixture ignites only in the exhaust manifold and the familiar "Bank Bang" occurs. This principle is however in the long run very harmful for the engine and should only be used in racing events.
