The all-new addition to the Turbosmart line-up is the fresh air ALV40 (Anti-Lag Valve) for motorsport applications. Featuring a 40mm valve diameter and a purpose designed actuator housing. Multiple fittings are also supplied for ease of fitment and fabrication.

The fresh air valve allows for incoming charged fresh air from the turbo to be diverted safely into the exhaust manifold pre-turbine wheel with the throttle at low opening angles to allow for safer spooling of the turbocharger without the potentially damaging throttle based late combustion event style anti-lag that can induce high engine stresses and break connecting rods.

The ALV is a sealed twin chamber design with the top port being the primary control port, the spring is designed to open under vacuum conditions to allow for the air to bypass into the exhaust manifold, the lower chamber for twin port control methods, to control the valve irrespective of manifold pressure and shaft seal allows for leak proof operation.

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.
