When adding boost to the N54 engine, it's important to consider effects throughout the rest of the system. Additional boost can overwhelm the stock BMW diverter valve system and lead to boost leakage, or boost spikes, and lost horsepower. With the factory components in place it's hard to maintain consistently high boost levels. Instead of the weak plastic components of the stock system, Active Autowerke uses a CNC-machined and mandrel-bent aluminum tube with a Venturi blow-off valve in place of the original diverter valves. The blow-off valve dumps overboost into the atmosphere for that distinctive turbo 'whoosh' sound. The single AA BOV is over-sized for the N54 application - taking the place of the two small diverter valves, and verified to handle over 600hp. With the BOV acting properly your turbos and other components are protected from compressor surge caused by excess pressure build-up.

We like the Active BOV better than other forms of diverter and BOV kits because it's tried and true - AA was the original turbo BMW tuners and their experience is second to none. That's why they took the time to engineer their kit to fit perfectly, using the OE-type connector to the throttle body, and high-strength silicone to the lower intercooler tube. Each connection is a tight, leak-free seal. The kit comes complete with the discharge tube, vacuum plugs for the stock hoses, and instructions. The tube is powdercoated in black and with a wrinkle finish for an OE appearance.

This item fits the following BMWs with N54 engine:
2008-2010 E82 BMW 135i 1M
2007-2010 E90 BMW 335i 335xi 335i xDrive

In addition to the weak stock chargepipe, the factory N54 diverter valves can also be a source for boost leaks. The diverter valve takes overboost and re-directs it back through the intake and turbos instead of allowing it to pass into the intake manifold. It's the same as a blow off valve (BOV) but instead of releasing into the engine bay, it stays contained to the engine. The stock diverter valves (DV) are plastic and connect with more plastic into the chargepipe and turbo inlet pipes. The plastic can become brittle and crack even on stock engines and leak boost, which leads to a loss in power and performance.

Turbosmart has developed two kits to replace and upgrade the stock diverter valves - a direct replacement kit and a combination DV/BOV "Dual Port" kit (shown). This Dual Port Kit is a DV and a BOV together in one unit. An internal valve directs some of the charged air into the turbo inlets and the rest is dumped into the engine bay like a traditional BOV. The amount of boost released into the air is determined by an internal spring in the Dual Port unit (additional springs are also available). This allows you to custom tailor how much boost and BOV "whoosh" you hear. In addition to the DV/BOV combo, stronger silicone hose is included to connect them to the turbo inlet pipes (Vargas silicone inlets are recommended). The Turbosmart Kompact Dual Port will give you all of the strength and reliability you need to take your turbo build to the next level.
