HYBRID TMS Dual Outlet (35mm inlet, 30mm outlet – suits MY97-98 WRX/STi)

🏁 THE ORIGINAL THAT STARTED IT ALL

Before modern adjustable BOVs, before venting bias technology, and before electronic control systems — there was the Hybrid.

First released in 1998, the Hybrid was the world’s first dual-port blow-off valve, designed to solve a real problem on early turbo Subaru platforms:
👉 atmosphere BOVs causing stalling and drivability issues on MAF-based engines.

⚙️ HOW IT WORKS

The Hybrid uses a staged dual-outlet design:

• 🟢 Recirculation port opens first
• 🔵 Atmospheric port opens progressively under higher lift

This staged operation allows:

• Stable airflow metering at low throttle lift
• Aggressive blow-off sound under hard driving
• Smooth drivability on MAF-equipped engines

---

🚀 KEY BENEFITS

• 🔊 Classic blow-off sound without drivability issues
• ⚡ Faster throttle recovery compared to factory bypass valves
• 🔒 Improved boost stability under gear changes
• 🧠 Prevents stalling, backfiring, and rich-running conditions
• 🏁 Proven dual-port staged venting design

🔬 EVOLUTION OF GFB TECHNOLOGY

The Hybrid didn’t just improve performance — it created a platform for future innovation:

• Hybrid → first dual-port staged vent system
• Respons TMS → adjustable venting bias control
• Deceptor Pro → electronic in-cabin vent adjustment

👉 The Hybrid is the foundation of modern GFB venting technology.

🧠 WHY IT WORKS

Traditional atmosphere BOVs on MAF systems often cause:

• Over-fuelling
• Hesitation
• Engine stalling

The Hybrid solves this by:

• Maintaining partial recirculation during light operation
• Only venting to atmosphere when boost demand increases
• Balancing airflow measurement and pressure relief

👉 Result: sound + performance without compromise.
