Turbosmart GenV ALV40 (Anti-Lag Valve)

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.

    Turbosmart


    Smarter Turbo Control, by Design

    Turbosmart is an Australian manufacturer of high-performance forced induction accessories, built around a simple but powerful idea: turbo control should be smarter, more precise, and more reliable than the standard solutions the industry has traditionally offered. Founded on genuine passion for performance, the brand has grown into a globally recognised name in the forced induction aftermarket, trusted by racers, tuners, and enthusiasts across the world who demand products engineered to win and built to last.

    A Global Standard, Set in Australia

    Turbosmart's vision is straightforward: to be the first choice worldwide for forced induction upgrades across both performance and service industries. That ambition is backed by a product range that spans everything a turbocharged vehicle demands, from street-performance daily drivers to dedicated full race builds requiring the highest levels of boost control precision. With a growing international presence and brand advocates spanning tracks and workshops across the globe, Turbosmart has firmly established itself as a name that resonates far beyond its Australian origins. Their in-house engineering department also takes on complex industrial applications where the same hallmarks of their racing pedigree, precision, heat management, vibration control, and repeatability, translate directly into real-world solutions. It is this ability to operate at the cutting edge of both motorsport and industry that keeps Turbosmart at the forefront of forced induction technology worldwide.

    Designed, Tested, and Manufactured In-House

    Every Turbosmart product is designed, rigorously tested, and manufactured entirely in-house, ensuring that quality and performance are never compromised by external variables. Their engineering team applies a motorsport-first development philosophy, if it cannot survive the demands of competition, it does not reach the market. The result is a range of boost controllers, wastegates, blow-off valves, and turbo accessories that consistently raise the benchmark for boost control efficiency, durability, and precision across a wide range of turbocharged platforms.
