What is compressor surge and how does this valve prevent it?

Compressor surge happens when the turbocharger's airflow is blocked, causing pressure to build up and then rapidly reverse back into the compressor. This can damage the turbo. The blow-off valve releases this excess pressure when you lift off the throttle, preventing surge and protecting your turbos.

Does this kit require any modifications to install?

No, this GReddy FV2 Blow Off Valve Kit is designed to be a direct bolt-on installation. It includes all the necessary adapters and hardware, so you won't need to cut or weld any factory lines.

What is the advantage of the dual-spring design on the FV2 valve?

The dual-spring design allows the FV2 valve to operate effectively across a wider range of boost pressures. This means it can handle both lower boost levels and significantly increased boost pressures from modifications more reliably than a single-spring valve.

Product Details

If you're looking to get the most out of your R35 GT-R's twin-turbo setup, especially if you've made modifications to increase boost pressure, a high-performance blow-off valve (BOV) is a crucial component. This GReddy FV2 Blow Off Valve Kit is specifically designed for the 2009-2020 Nissan GT-R, featuring the VR38DETT engine. It replaces the factory unit to help protect your turbochargers from damaging compressor surge when you lift off the throttle during spirited driving or hard acceleration.

The FV2 BOV uses a unique dual-spring design that allows for a wider operating range, meaning it can handle both lower and higher boost pressures more effectively than a single-spring setup. This translates to improved turbo response and longevity. The kit includes all the necessary adapters and hardware for a direct installation, meaning you won't need to cut or weld any factory lines. GReddy is well-known for its performance parts, and this BOV kit is built with their experience in mind, using durable materials to withstand the heat and pressure under the hood.

When installing this kit, it's important to note that it is not CARB approved and cannot be shipped to California. Ensure you have the correct tools for a clean installation, and always refer to the manufacturer's instructions for specific details. This kit is a solid choice for GT-R owners who want to ensure their forced induction system is protected and performing at its best.
