HYBRID TMS Dual Outlet (20mm inlet, 20mm outlet)

🔧 Product Description

The GFB Hybrid TMS Dual Outlet Blow-Off Valve is a legendary design from Go Fast Bits, originally released in 1998 as the world’s first dual-port (recirc + atmosphere) BOV. Now re-released, the Hybrid combines proven performance with modern flexibility, making it ideal for turbocharged street and performance builds.

Designed to solve common issues with atmosphere-only BOVs (like stalling on MAF-equipped vehicles), the Hybrid uses staged dual outlets—where the recirculation port opens first, followed by the atmosphere vent—ensuring smooth drivability while still delivering that iconic blow-off sound under load.

⚙️ Key Features

• Dual outlet design (recirc + atmosphere venting)
• 20mm inlet / 20mm outlet size
• Staged venting system for smooth operation on MAF vehicles
• Configurable for:
  • Full recirculation
  • Full atmosphere venting
  • 50/50 hybrid venting
• Proven design used across multiple generations of GFB valves
• Lightweight, durable construction with anodised finish

🏁 Performance Benefits

• Prevents stalling and backfiring on MAF-based engines
• Maintains stable idle and drivability
• Delivers responsive boost recovery
• Produces the signature blow-off sound under load
• Ideal balance between performance and daily usability

This staged venting technology became so effective that it has since been widely adopted across the blow-off valve market.

🏆 Heritage & Innovation

The Hybrid BOV was invented by GFB engineer John Adrian, frustrated by drivability issues on his turbocharged Subaru. His solution became a world-first innovation, later evolving into:

• GFB Respons TMS (adjustable venting bias)
• GFB Deceptor Pro (electronic control)

To celebrate its impact, the Hybrid received a Global Media Award at the SEMA Show 2017, selected from over 3000 entries.
