The all-new addition to the Turbosmart line-up is the fresh air ALV40 (Anti-Lag Valve). They are designed to create a broader market for motorsport applications.
The anti-lag valve provides a means to maintain turbine speed, eliminate lag on gear changes & deceleration. This is achieved by allowing incoming charged fresh air from the turbo to be diverted safely into the exhaust manifold pre-turbo 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.
When the ALV valve is active, boost pressure is diverted around the engine (instead of going through it) into the exhaust manifold. Combined with fuel and ignition strategies (from the ECU), the turbo speed is maintained, and more importantly, a useable boost is ready for when the throttle is opened again.
ALV40 Features
The ALV40 features a 40mm valve diameter, a purpose-designed actuator housing with a sealed twin-chamber design and the top port being the primary control port. The spring is designed to open under vacuum conditions to allow the air to bypass the exhaust manifold. The lower chamber is utilised for twin-port control methods to control the valve irrespective of manifold pressure. The shaft seal allows for leakproof operation. Also, multiple fittings are supplied for ease of fitment and fabrication.
Developed for a variety of engine configurations; an outlet weld flange is required to be purchased separately to the correct application. The outlet system you require will depend on how you intend to plumb your ALV40 to your exhaust manifold. There are options to suit virtually all internal combustion engines either by plumbing into each cylidner runner, every 2nd cylinder runner or even into just 2 seperate turbocharger scrolls. Outlet flanges to suit multiple outlets (listed below) will need to be purchased seperately
- 1-2 Outlet: TS-0550-3100
- 1-3 Outlet: TS-0550-3099
- 1-4 Outlet: TS-0550-3098
- 1-5 Outlet: TS-0550-3104
- 1-6 Outlet: TS-0550-3114
For custom outlet plenums, use Single Outlet (TS-0550-3101) to allow for the fabrication of your own solution.
Inside the box you will find:
- Turbosmart GenV ALV

Anti-lag | Do you have the best boost Response?
Engineered to Win!
Anti-lag is already a well-proven option to improve boost response on turbocharged engines, but Turbosmart has a new way to implement it via their Anti-lag valve. Traditionally anti-lag is operated via the throttle body, whereas Turbosmarts ALS valve does things a little differently, as explained by Andre at the 2018 Performance Racing Industry trade show.
