The Z1 Turbosmart Blow Off Valve Kit includes everything needed to install blow-off valves on 3.0t (VR30) equipped Infiniti Q50 Sedans and Q60 Coupes.
Why do I need blow-off valves?
A blow-off valve's sole purpose is to protect your turbo. The valve is actuated by manifold vacuum and designed to vent excess boost pressure into the atmosphere on forced induction cars when the throttle is closed. This release of boost pressure prevents damaging reverse shock waves from reaching your turbo while creating the infamous "psshhhh" sound that turbo cars are known for. Without this release, pressurized air can damage the turbine shaft bearings and compressor wheel. In more extreme cases the compressor wheel can literally explode in the housing.
Due to the complete lack of recirculation or blow-off valves on the VR30 powertrain, boost pressure remains in the intake tract when transitioning off throttle. When increasing boost pressure and tuning this leaves the tuner with two options:
A: Slamming the throttle shut when lifting off throttle. Boost pressure is not bled off, resulting in reverse thrust on the turbo's compressor wheel. This shock-load causes accelerated turbo thrust bearing wear, which can destroy the turbo.
B: Gradually shutting the throttle when lifting off-throttle (this is the "I'll risk my car and life to save these turbos" scenario). It's like this, you have just been making a sweet power pull and the car has broken traction at about 60 mph. You're now sideways and you can't reel it back in straight so you release the throttle, but this evil car is still boosting away accelerating as you look at that oncoming telephone pole. If you're lucky you'll save it and order this kit before you have to buy replacement bodywork. If you didn't save it we have replacement body panels here, and you have to hope that no one got a video of you going full Mustang.
After installing blow-off valves, the boost pressure is then vented to the atmosphere. This saves the turbos from accelerated thrust bearing and compressor wear and lets you drive your car like it's meant to be driven.

Aftermarket blow-off valves like the Turbosmart VeePort Pro included in this kit have the ability to flow a high volume of air, ideal for higher boost applications where the boost pressure has been increased. Designed for high flow and performance, the VeePort features a 38mm piston and unique boost-balance technology that can support more boost than the VR30 platform will ever need. This version of their popular blow-off valve was manufactured exclusively for Z1!
