HYBRID TMS Dual Outlet Blow-Off Valve (Skyline GTS-T R32-34, Mazda 3 & 6 MPS, CX-7)

🔧 Product Description

The HYBRID TMS Dual Outlet Blow-Off Valve from Go Fast Bits (GFB) is a world-first dual-port venting system designed for turbocharged performance platforms including Nissan Skyline RB-series engines and Mazda MPS / CX-7 MZR DISI turbo applications.

Originally engineered to solve stalling and compressor surge issues caused by atmospheric BOVs on MAF-based systems, the Hybrid combines stable recirculation with aggressive atmospheric venting under load.

Its staged dual-outlet design ensures smooth airflow management while still delivering the signature turbo blow-off sound.

🏁 Performance Benefits

⚡ Improved Throttle Response

Reduces compressor surge and maintains stable airflow during gear changes for sharper throttle response.

🚀 Faster Boost Recovery

Helps the turbo return to peak boost faster after throttle lift, improving acceleration and drivability.

🔒 Stable Boost Control

Staged venting reduces sudden pressure loss, improving consistency under load and preventing airflow disruption.

🔬 How the Hybrid System Works (TMS Technology)

The Turbo Management System (TMS) uses a dual-stage venting strategy:

• Recirculation port opens first → stabilises airflow and prevents stalling
• Atmospheric port opens under higher boost demand → provides blow-off sound
• Progressive closure preserves intercooler pressure for faster recovery

👉 Result: smoother transitions, reduced lag, and improved turbo response
