The ALV (TS-0552-1402) is designed to bring a typical high-end motorsport application to a wider market for the racing industry. It generated so much hype that the product was welcomed with two separate media awards from different publishers across the world, in addition to Best New Product Award for Performance-Street with the Turbosmart Universal EM-Blow Off Valve.
The anti-lag valve provides a means to maintain turbine speed and eliminate lag on gear changes & deceleration. Boost pressure from the turbo is diverted around the engine on these closed throttle situations and combined with a fuel and ignition strategy (from the ECU) ensuring the turbine speed is maintained and useable boost is on the ready, for when the throttle is opened again.
Chris Doumbos, Turbosmart Head Engineer, the pioneer behind the Award Winning Universal EM BOV, explains a little bit about the Anti-Lag Valve.
“The fresh air valve allows for incoming fresh air to be diverted safely into the exhaust manifold, pre-turbo with the throttle closed to allow for safer spooling of the turbocharger without the potentially damaging combustion event style anti-lag that can induce high engine & turbo stresses, even break connecting rods”, states Doumbos.
“The fresh air ALS valve 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.”
The all-new addition to the Turbosmart lineup, the fresh air ALV40 (Anti-Lag Valve). Featuring a 40mm valve diameter, a purpose-designed actuator housing, inverted diaphragm and supplied with multiple fittings for ease of fitment and fabrication.
