Reference Information

Turbocharger Componet, Anti-Lag Valve, 40mm, Each

An all-new addition to the Turbosmart lineup is the fresh air Gen-V (Anti-Lag Valve (ALV40) for motorsport applications. They feature a 40mm valve diameter, a purpose-designed actuator housing—and multiple fittings for ease of fitment and fabrication. The anti-lag 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, this allows for safer spooling of the turbocharger—without the potentially damaging throttle-based late combustion 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; while the lower chamber is for twin port control methods—to control the valve irrespective of manifold pressure. The shaft seal allows for leak-proof operation.
