2 or 4-cylinder flange ALV40 Gen-V Anti-Lag valveALV40 Gen-V Anti-Lag exhaust flange for 2 or 4-cylinder enginesOutlet weld-on flange for Turbosmart ALV40 GEN 5 Anti-Lag WastegateStainless steel outlet welding adapter for 2 or 4-cylinder engines, suitable for the Turbosmart ALV40 Gen-V Anti-Lag Wastegate.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. Note: Suitable for 2 or 4-cylinder enginesMaterial: stainless steel
